For Safe Operations 1. Prevention of electric shocks
! DANGER Never open the front case or terminal covers while the power is ON or the unit is running, as this may lead to electric shocks.
Never run the unit with the front case or terminal cover removed. The high voltage terminal and charged sections will be exposed and may lead to electric shocks. Never open the front case or terminal cover at times other than wiring work or periodic inspections even if the power is OFF. The insides of the Motion controller and servo amplifier are charged and may lead to electric shocks. When performing wiring work or inspections, turn the power OFF, wait at least ten minutes, and then check the voltage with a tester, etc.. Failing to do so may lead to electric shocks. Be sure to ground the Motion controller, servo amplifier and servomotor. (Ground resistance : 100 or less) Do not ground commonly with other devices. The wiring work and inspections must be done by a qualified technician. Wire the units after installing the Motion controller, servo amplifier and servomotor. Failing to do so may lead to electric shocks or damage. Never operate the switches with wet hands, as this may lead to electric shocks. Do not damage, apply excessive stress, place heavy things on or sandwich the cables, as this may lead to electric shocks. Do not touch the Motion controller, servo amplifier or servomotor terminal blocks while the power is ON, as this may lead to electric shocks. Do not touch the built-in power supply, built-in grounding or signal wires of the Motion controller and servo amplifier, as this may lead to electric shocks.
2. For fire prevention
! CAUTION Install the Motion controller, servo amplifier, servomotor and regenerative resistor on inflammable material. Direct installation on flammable material or near flammable material may lead to fire.
If a fault occurs in the Motion controller or servo amplifier, shut the power OFF at the servo amplifiers power source. If a large current continues to flow, fire may occur. When using a regenerative resistor, shut the power OFF with an error signal. The regenerative resistor may abnormally overheat due to a fault in the regenerative transistor, etc., and may lead to fire. Always take heat measures such as flame proofing for the inside of the control panel where the servo amplifier or regenerative resistor is installed and for the wires used. Failing to do so may lead to fire.
A - 3
3. For injury prevention
! CAUTION Do not apply a voltage other than that specified in the instruction manual on any terminal. Doing so may lead to destruction or damage. Do not mistake the terminal connections, as this may lead to destruction or damage. Do not mistake the polarity ( + / - ), as this may lead to destruction or damage. Do not touch the servo amplifier's heat radiating fins, regenerative resistor and servomotor, etc., while the power is ON and for a short time after the power is turned OFF. In this timing, these parts become very hot and may lead to burns.
Always turn the power OFF before touching the servomotor shaft or coupled machines, as these parts may lead to injuries.
Do not go near the machine during test operations or during operations such as teaching. Doing so may lead to injuries.
4. Various precautions
Strictly observe the following precautions.
Mistaken handling of the unit may lead to faults, injuries or electric shocks.
(1) System structure
! CAUTION Always install a leakage breaker on the Motion controller and servo amplifier power source. If installation of an electromagnetic contactor for power shut off during an error, etc., is specified in the instruction manual for the servo amplifier, etc., always install the electromagnetic contactor. Install the emergency stop circuit externally so that the operation can be stopped immediately and the power shut off. Use the Motion controller, servo amplifier, servomotor and regenerative resistor with the combi- nations listed in the instruction manual. Other combinations may lead to fire or faults. If safety standards (ex., robot safety rules, etc.,) apply to the system using the Motion controller, servo amplifier and servomotor, make sure that the safety standards are satisfied. Construct a safety circuit externally of the Motion controller or servo amplifier if the abnormal operation of the Motion controller or servo amplifier differ from the safety directive operation in the system. In systems where coasting of the servomotor will be a problem during the forced stop, emergency stop, servo OFF or power supply OFF, use dynamic brakes. Make sure that the system considers the coasting amount even when using dynamic brakes. In systems where perpendicular shaft dropping may be a problem during the forced stop, emergency stop, servo OFF or power supply OFF, use both dynamic brakes and electromagnetic brakes. The dynamic brakes must be used only on errors that cause the forced stop, emergency stop, or servo OFF. These brakes must not be used for normal braking.
A - 4
! CAUTION The brakes (electromagnetic brakes) assembled into the servomotor are for holding applications, and must not be used for normal braking.
The system must have a mechanical allowance so that the machine itself can stop even if the stroke limits switch is passed through at the max. speed. Use wires and cables that have a wire diameter, heat resistance and bending resistance compatible with the system. Use wires and cables within the length of the range described in the instruction manual. The ratings and characteristics of the parts (other than Motion controller, servo amplifier and servomotor) used in a system must be compatible with the Motion controller, servo amplifier and servomotor. Install a cover on the shaft so that the rotary parts of the servomotor are not touched during operation. There may be some cases where holding by the electromagnetic brakes is not possible due to the life or mechanical structure (when the ball screw and servomotor are connected with a timing belt, etc.). Install a stopping device to ensure safety on the machine side.
(2) Parameter settings and programming
! CAUTION Set the parameter values to those that are compatible with the Motion controller, servo amplifier, servomotor and regenerative resistor model and the system application. The protective functions may not function if the settings are incorrect.
The regenerative resistor model and capacity parameters must be set to values that conform to the operation mode, servo amplifier and servo power supply module. The protective functions may not function if the settings are incorrect. Set the mechanical brake output and dynamic brake output validity parameters to values that are compatible with the system application. The protective functions may not function if the settings are incorrect. Set the stroke limit input validity parameter to a value that is compatible with the system application. The protective functions may not function if the setting is incorrect. Set the servomotor encoder type (increment, absolute position type, etc.) parameter to a value that is compatible with the system application. The protective functions may not function if the setting is incorrect. Set the servomotor capacity and type (standard, low-inertia, flat, etc.) parameter to values that are compatible with the system application. The protective functions may not function if the settings are incorrect. Set the servo amplifier capacity and type parameters to values that are compatible with the system application. The protective functions may not function if the settings are incorrect. Use the program commands for the program with the conditions specified in the instruction manual.
A - 5
! CAUTION Set the sequence function program capacity setting, device capacity, latch validity range, I/O assignment setting, and validity of continuous operation during error detection to values that are compatible with the system application. The protective functions may not function if the settings are incorrect.
Some devices used in the program have fixed applications, so use these with the conditions specified in the instruction manual. The input devices and data registers assigned to the link will hold the data previous to when communication is terminated by an error, etc. Thus, an error correspondence interlock program specified in the instruction manual must be used. Use the interlock program specified in the special function module's instruction manual for the program corresponding to the special function module.
(3) Transportation and installation
! CAUTION Transport the product with the correct method according to the mass. Use the servomotor suspension bolts only for the transportation of the servomotor. Do not transport the servomotor with machine installed on it.
Do not stack products past the limit. When transporting the Motion controller or servo amplifier, never hold the connected wires or cables.
When transporting the servomotor, never hold the cables, shaft or detector. When transporting the Motion controller or servo amplifier, never hold the front case as it may fall off.
When transporting, installing or removing the Motion controller or servo amplifier, never hold the edges.
Install the unit according to the instruction manual in a place where the mass can be withstood. Do not get on or place heavy objects on the product. Always observe the installation direction. Keep the designated clearance between the Motion controller or servo amplifier and control panel inner surface or the Motion controller and servo amplifier, Motion controller or servo amplifier and other devices.
Do not install or operate Motion controller, servo amplifiers or servomotors that are damaged or that have missing parts.
Do not block the intake/outtake ports of the servomotor with cooling fan. Do not allow conductive matter such as screw or cutting chips or combustible matter such as oil enter the Motion controller, servo amplifier or servomotor.
The Motion controller, servo amplifier and servomotor are precision machines, so do not drop or apply strong impacts on them.
A - 6
! CAUTION Securely fix the Motion controller and servo amplifier to the machine according to the instruction manual. If the fixing is insufficient, these may come off during operation.
Always install the servomotor with reduction gears in the designated direction. Failing to do so may lead to oil leaks. Store and use the unit in the following environmental conditions.

(8) Maintenance, inspection and part replacement
! CAUTION Perform the daily and periodic inspections according to the instruction manual. Perform maintenance and inspection after backing up the program and parameters for the Motion controller and servo amplifier. Do not place fingers or hands in the clearance when opening or closing any opening. Periodically replace consumable parts such as batteries according to the instruction manual. Do not touch the lead sections such as ICs or the connector contacts. Do not place the Motion controller or servo amplifier on metal that may cause a power leakage or wood, plastic or vinyl that may cause static electricity buildup. Do not perform a megger test (insulation resistance measurement) during inspection. When replacing the Motion controller or servo amplifier, always set the new module settings correctly. When the Motion controller or absolute value motor has been replaced, carry out a home position return operation using one of the following methods, otherwise position displacement could occur. 1) After writing the servo data to the Motion controller using programming software, switch on the
power again, then perform a home position return operation. 2) Using the backup function of the programming software, load the data backed up before
replacement. After maintenance and inspections are completed, confirm that the position detection of the absolute position detector function is correct. Do not short circuit, charge, overheat, incinerate or disassemble the batteries. The electrolytic capacitor will generate gas during a fault, so do not place your face near the Motion controller or servo amplifier. The electrolytic capacitor and fan will deteriorate. Periodically replace these to prevent secondary damage from faults. Replacements can be made by our sales representative.

3.2.1 Axis monitor devices
The monitoring data area is used by the Motion CPU to store data such as the feed current value during positioning control, the real current value and the number of droop pulses in the deviation counter. It can be used to check the positioning control state using the Motion SFC program. The user cannot write data to the monitoring data area (except the travel value change register). Refer to APPENDIX 5 "Processing Time of the Motion CPU" for the delay time between a positioning device (input, internal relay and special relay) turning on/off and storage of data in the monitor data area. (1) Feed current value storage register (D0+20n, D1+20n)
...... Monitor device (a) This register stores the target address output to the servo amplifier on the
basis of the positioning address/travel value specified with the servo program. 1) A part for the amount of the travel value from "0" after starting is stored in
the fixed-pitch feed control. 2) The current value from address at the time of starting is stored in the
speed/position switching control. However, the address at the time of starting varies depending on the ON/OFF state of the feed current value update command (M3212+20n) at the start. M3212+20n: OFF ..... Resets the feed current value to "0" at the start. M3212+20n: ON ..... Not reset the feed current value at the start. 3) "0" is stored during speed control.
(b) The stroke range check is performed on this feed current value data.
(2) Real current value storage register (D2+20n, D3+20n)
...... Monitor device (a) This register stores the real current value which took the droop pulses of the
servo amplifier into consideration to the feed current value.
(b) The "feed current value" is equal to the "real current value" in the stopped state.
(3) Deviation counter value storage register (D4+20n, D5+20n)
...... Monitor device This register stores the droop pulses read from the servo amplifier.
(4) Minor error code storage register (D6+20n) ............. Monitor device
(a) This register stores the corresponding error code (Refer to APPENDIX 1.2) at the minor error occurrence. If another minor error occurs after error code storing, the previous error code is overwritten by the new error code.
(b) Minor error codes can be cleared by an error reset command (M3207+20n).
3 - 47
3 POSITIONING DEDICATED SIGNALS
(5) Major error code storage register (D7+20n) ............. Monitor device
(a) This register stores the corresponding error code (Refer to APPENDIX 1.3) at the major error occurrence. If another major error occurs after error code storing, the previous error code is overwritten by the new error code.
(b) Major error codes can be cleared by an error reset command (M3207+20n).
(6) Servo error code storage register (D8+20n) ......... Monitor device
(a) This register stores the corresponding error code (Refer to APPENDIX 1.4) at the servo error occurrence. If another servo error occurs after error code storing, the previous error code is overwritten by the new error code.
(b) Servo error codes can be cleared by an error reset command (M3208+20n).
(7) Home position return re-travel value storage register (D9+20n)
...... Monitor device If the position stopped in the position specified with the travel value setting (Refer to Section 6.23.1) after the proximity dog ON by a peripheral device is not zero point, it made to travel to zero point by re-travel in the Motion CPU. The travel value (signed) of making it travel to zero point by re-travel at this time is stored. (Data does not change with the last value in the data setting type.) The following value is stored according to the number of feedback pulses of the motor connected.
Number of feedback pulses Storage data Less than 131072[PLS] Feedback pulses 131072[PLS] or more, 262144[PLS] or less 1/10 of feedback pulses More than 262144[PLS] 1/10000 of feedback pulses
(8) Travel value after proximity dog ON storage register
(D10+20n, D11+20n) Monitor device (a) This register stores the travel value (unsigned) from the proximity dog ON to
home position return completion after the home position return start.
(b) The travel value (signed) of the position control is stored at the time of speed/position switching control.

(12) Data set pointer for constant-speed control (D15+20n)
...... Monitor device This pointer is used in the constant-speed control when specifying positioning data indirectly and substituting positioning data during operation. It stores a "point" that indicates which of the values stored in indirect devices has been input to the Motion CPU when positioning is being repeated by using a repetition instructions (FOR-TIMES, FOR-ON or FOR-OFF). Use this pointer in conjunction with the updated data set pointer (controlled by the user in the Motion SFC program) - which indicates the extent to which the positioning data has been updated using the Motion SFC program - to confirm which positioning data is to be updated. Data set pointer for constant-speed control and updated data set pointer are described here using the example servo program below.

3 POSITIONING DEDICATED SIGNALS
[Internal processing]
(a) The positioning data ((1) to (14)) of points 0 to 6 is input to the Motion CPU by the starting. The last point "6" of the input data to be input is stored in the data set pointer for constant-speed control at this time. The "6" stored in the data set pointer for constant-speed control indicates that updating of the positioning data stored in points 0 to 6 is possible.
(b) The positioning data ((A) to (D)) of points 0 to 1 is updated using the Motion
SFC program. The last point "1" of the positioning data to be rewritten is stored in the updated data set pointer (which must be controlled by the user in the Motion SFC program). Updating of positioning data of points 2 to 6 (data (5) to (14)) remains possible.
(c) On completion of the positioning for point 0, the value in the data set pointer
for constant-speed control is automatically incremented by one to "7". The positioning data ((1) to (2)) of point 0 is discarded and the positioning data ((15) to (16)) for point 7 is input to the Motion CPU at this time.
(d) Hereafter, whenever positioning of each point is completed, the positioning
data shifts one place. The positioning data that can be updated is the data after that indicated by the updated data set pointer: this is the data which has not yet been input to the Motion CPU. Even if the values of the indirect devices D8 and D10 are updated by the Motion SFC program after the positioning completion of the point 3, the positioning data of point 2 that is input to the Motion CPU will not be updated and the second positioning will be executed using the unupdated data. The data set pointer for constant-speed control has not yet been input to the Motion CPU, and indicates the positioning data which a user can update using the Motion SFC program.
POINT
Number of points that can be defined by a repeat instruction Create the servo program at least eight points. If there are less than eight points and they include pass points of few travel value,
the positioning at each point may be completed, and the data input to the Motion CPU, before the data has been updated using the Motion SFC program. Create a sufficient number of points to ensure that data will not be input before the Motion CPU has updated the values in the indirect devices.

(1) Number of pulses/travel value per rotation
Number of pulses(AP)/travel value(AL) per rotation is an item which determines how many rotations (number of pulses per rotation) of the servomotor in order to make it a machine as the travel value ordered by the program. The position control toward the servomotor is controlled with the number of feedback pulses of the encoder connected to the servomotor in the servo amplifier. The control content of the Motion CPU is shown below.

For example, suppose that the servomotor was connected to the ball screw. Because the travel value ( S) of machine per motor rotation is [mm] / [inch] unit, the travel value (positioning address) set in the program is commanded in [mm] / [inch] unit. However, the servomotor is positioning controlled by the servo amplifier in pulse unit.

4 PARAMETERS FOR POSITIONING CONTROL
Therefore, AP/AL is set so that the following expression of relations may be materialized in order to convert the travel value of [mm] / [inch] unit set in the program into a pulse.
Number of pulses per motor rotation = AP Travel value of machine per motor rotation = AL
= AP AL

(There is a range which can be set in the numerical value set as AP/AL, so it is necessary to make the setting range of AP/AL the value calculated from the above expression (reduced) of relations.) Example of the real setting is shown below.
(a) For ball screw
When the ball screw pitch is 20[mm], the servomotor is HF-KP (262144[PLS/rev]) and direct connection (No reduction gear) is set.

Motor
Fig. 4.2 For ball screw
First, find how many millimeters the load (machine) will travel (AL) when the servomotor runs for one rotation (AP). AP (Number of pulses per motor rotation) = 262144[PLS] AL (Travel value of machine per rotation)
= Ball screw pitch Reduction ratio = 20[mm]
Substitute this for the above expression (1).
= AP AL
262144[PLS] 20[mm]
Although it becomes above, when a control unit is set to [mm] unit, the minimum unit of the command value in a program is 0.1[m] and converted from 20[mm] (20.0000[mm]) to 20000.0[m].
= AP AL
262144[PLS] 20000.0[ m]

4 PARAMETERS FOR POSITIONING CONTROL
The travel value per motor rotation in this example is 0.000076[mm]. For example, when ordering the travel value of 19[mm], it becomes 249036.8[PLS] and the fraction of 0.8[PLS]. At this time, the Motion CPU orders the travel value of 249036[PLS] to the servomotor and the fraction is memorized in the Motion CPU. Positioning is performed by seasoning the travel value with this fraction at the next positioning.
4.2.2 Backlash compensation amount
(1) Backlash compensation amount can be set within the following range. (Refer to Section "7.2 Backlash Compensation Function" for details.)
Backlash compensation amount Number of pulses per rotation (AP)

(2) The servo error may occur depending on the type of the servo amplifier
(servomotor) or operation cycle even if the backlash compensation amount which fulfill the above condition. Set the backlash compensation amount within the following range in order for servo error may not occur.

The stroke limit range is checked at the following start or during operation. Operation start Check Remarks
Position follow-up control Constant-speed control Speed switching control Positioning control Fixed-pitch feed control
Check
It is checked whether the feed current value is within the stroke limit range or not at the positioning start. If it outside the range, an error occurs (error code: 106) and positioning is not executed.
If the interpolation path exceeds the stroke limit range during circular interpolation start, an error occurs (error codes: 207, 208) and deceleration stop is executed.
If the current value exceeds the stroke limit range, deceleration stop is executed.
Speed control ( ) Speed control ( )
Not check The current value becomes "0", and operation continues
until the external limit signal (FLS, RLS, STOP) is received.
Speed/position switching control (including restart)
It is checked after the switch to position control.
JOG operation
When the current value is executed a deceleration stop from current command speed, if the current value exceeds the stroke limit range, a deceleration stop is made before a stroke limit. (Error code: 207) Travel to the direction that returns the axis into the stroke range is possible.
Manual pulse generator operation
Check
If the current value exceeds the stroke limit range, it stops at stroke limit. (Error code: 207) In this case, a deceleration stop is not made. Travel to the direction that returns the axis into the stroke range is possible.
POINTS
(1) Besides setting the upper/lower stroke limit value in the fixed parameters, the stroke limit range can also be set by using the external limit signals (FLS, RLS).
(2) When the external limit signal turns off, a deceleration stop is executed.
"Deceleration time" and "Rapid stop deceleration time" can be used in the parameter block for deceleration stop time.

4.2.4 Command in-position range
The command in-position is the difference between the positioning address (command position) and feed current value. Once the value for the command in-position has been set, the command in-position signal (M2403+20n) turns on when the difference between the command position and the feed current value enters the set range [(command position - feed current value) (command in-position range)]. The command in-position range check is executed continuously during position control.

4.3.1 Relationships between the speed limit value, acceleration time, deceleration time and
rapid stop deceleration time
The speed limit value is the maximum speed at the positioning/home position return. The acceleration time is the time taken to reach the set speed limit value from the start of positioning. The deceleration time and rapid stop deceleration time are the time taken to effect a stop from the set speed limit value. Accordingly, the actual acceleration time, deceleration time, and rapid stop deceleration time are faster, because the positioning speed is faster than the speed limit value.

Errors are set in the error item information area (D9190). Setting of the S-curve ratio enables acceleration/deceleration processing to be executed gently.

4.3.3 Allowable error range for circular interpolation
The locus of the arc calculated from the start point address and central point address may not coincide with the set end point address for the central-specified control. The allowable error range for circular interpolation sets the allowable range for the error between the locus of the arc determined by calculation and the end point address. If the error is within the allowable range, circular interpolation to the set end point address is executed while also executing error compensation by means of spiral interpolation. If it exceeds the setting range, an error occurs at the start and positioning does not start. Such an error are set the applicable axis or minor error code area.

5.4 Setting Method for Positioning Data
This section describes how to set the positioning data used in the servo program. There are two ways to set positioning data, as follows: (1) Setting by specifying numerical values Refer to Section 5.4.1
(2) Indirect setting by word devices . Refer to Section 5.4.2
"Setting by specifying numerical values" and "indirect setting by word devices" can be used together in one servo program.
5.4.1 Setting method by specifying numerical values
In the setting method by specifying numerical values, each positioning data is set by a numerical value, and it becomes fixed data. Data can be set and corrected using a peripheral device only.

6. POSITIONING CONTROL
This section describes the positioning control methods. 6.1 Basics of Positioning Control
This section describes the common items for positioning control, which is described in detail after Section 6.2.
6.1.1 Positioning speed
The positioning speed is set using the servo program. Refer to Chapter 5 for details of the servo programs. The real positioning speed is set in the positioning speed and speed limit value using the servo program is shown below: If the positioning speed setting is less than speed limit value, the positioning is
executed with the setting positioning speed. If the positioning speed setting is less than speed limit value, the positioning is
executed with the positioning speed.
(1) If the speed limit value is 120000[mm/min] and the positioning speed setting is
100000[mm/min], the positioning speed is as follows.

6 POSITIONING CONTROL
6.1.2 Positioning speed at the interpolation control
The positioning speed of the Motion CPU sets the travel speed of the control system. (1) 1 axis linear control
Travel speed is the positioning speed of the specified axis at the 1 axis positioning control.
(2) Linear interpolation control
Positioning is controlled with the speed which had the control system specified at the interpolation control. The positioning speed can be set using one of the following three methods at the 2 to 4 axes linear interpolation control: Combined-speed specification Long-axis speed specification Reference-axis speed specification Control method of the Motion CPU control for every specified method is shown below. (a) Combined-speed specification
The Motion CPU calculates the positioning speed of each axis (V1 to V2) using the travel value (D1 to D4) of each axis based on the positioning speed (V) of the setting control system. Positioning speed of the control system is called the combined-speed. Set the combined-speed and the travel value of each axis in the servo program.

6 POSITIONING CONTROL
(b) Long-axis speed specification
It is controlled based on the positioning speed (Long-axis speed: V) of the largest travel value axis among address set as each axis. The Motion CPU calculates the positioning speed of other axes (V1 to V3) using the each axis travel value (D1 to D4). Set the long-axis speed and the travel value of each axis using the servo program.
4 axes linear interpolation control is shown below.
[Program example] Axis 1 travel value: D1 = 10000[PLS] Axis 2 travel value: D2 = 15000[PLS] Axis 3 travel value: D3 = 5000[PLS] Axis 4 travel value: D4 = 20000[PLS] Long-axis speed: V = 7000[PLS/s] In this example, since the reference axis
is axis 4 of the largest travel value, it is controlled with the positioning speed specified with axis 4.
The Motion CPU calculates the positioning speed of other axes using the following calculation formulas:

The following conversions are performed if the control units of each axis differ. 1) Combination of axes set in [mm] and [inch]
a) If the interpolation control units are [mm] Travel value: Convert the travel value of axis set in [inch] into [mm]
using the formula: inch setting value 25.4. Speed : The largest travel value axis is controlled with the long-
axis speed and the other axes are controlled with the speed based on the long-axis speed, as the result of conversion.
b) If the interpolation control units are [inch] Travel value: Convert the travel value of axis set in [mm] into [inch]
using the formula: mm setting value 25.4. Speed : The largest travel value axis is controlled with the long-
axis speed and the other axes are controlled with the speed based on the long-axis speed, as the result of conversion.
2) Discrepancy between interpolation control units and control units Travel value: The travel value of each axis is converted into [PLS] unit
with the electronic gear of self axis.
Example

6 POSITIONING CONTROL
Speed : The largest travel value axis is controlled with the long-
axis speed and the other axes are controlled with the speed based on the long-axis speed, as the result of conversion. The positioning speed is converted into [PLS/s] unit as the long-axis speed with the electronic gear that the interpolation control units correspond to control units.

6 POSITIONING CONTROL
POINTS
(1) Speed limit value and positioning speed The setting speed limit value applies to the long-axis speed. Be careful that the combined-speed may exceed the speed limit value at the
long-axis speed specification. The following settings at the 2 axes linear interpolation, the combined-speed
exceeds the speed limit value.
Axis 1 travel value : 100 [PLS] Axis 2 travel value : 200 [PLS] Long-axis speed : 50 [PLS/s] Speed limit value : 55 [PLS/s]
In this example, since the reference-axis is axis 2 of the largest travel value, it is controlled with the speed limit value specified with axis 2.
The positioning speed and combined-speed for each axis are as follows:
Axis 1 positioning speed : 100/ 200 50 = 25 [PLS/s] Axis 2 positioning speed : 50 [PLS/s] Combined-speed : 25 + 50 = 55.9[PLS/s]2 2

If the control units of axes to be interpolation- controlled are the same, control starts in the preset control unit.
If the control units of axes to be interpolation- controlled are different, control starts in the unit of highest priority as indicated below.
Priority: PLS > degree > inch > mm
If axis is set to 1000[PLS] and 10.000[inch], 10.000[inch] setting is considered to be 10000[PLS].

(2) The combinations of each axis control units for interpolation control are shown in
the table below. Mm inch degree PLS
mm 1) 2) 3) 3) inch 2) 1) 3) 3)
degree 3) 3) 1) 3) PLS 3) 3) 3) 1)
Remarks
1): Same units 2): Combination of [mm] and [inch] 3): Unit mismatch
(a) Same units ( 1) ) The position command is calculated with the setting address (travel value), positioning speed or electronic gear, the positioning is executed.
POINT
If control units for one axis are "degrees" at the circular interpolation control, use "degrees" also for the other axis.
(b) Combination of [mm] and [inch] ( 2) )
If interpolation control units are [mm], positioning is controlled by calculating position commands from the address, travel value, positioning speed and electronic gear, which have been converted to [mm] using the formula: inch setting value 25.4 = mm setting value.
If interpolation control units are [inch], positioning is controlled by calculating position commands from the address, travel value, positioning speed and electronic gear, which have been converted to [inch] using the formula: mm setting value 25.4 = inch setting value.
(c) Discrepancy units ( 3) ) The travel value and positioning speed are calculated for each axis.
a) The electronic gear converts the travel value for the axis to [PLS]. b) For axis where the units match, the electronic gear converts the
positioning speed to units of [PLS/s]. Positioning is conducted using position commands calculated from travel values converted to [PLS] and speeds and electronic gear converted to [PLS/s].
If the interpolation control units match for two or more axes at the 3-axes or more linear interpolation, the positioning speed is calculated with the electronic gear for the axis with the lowest No.

6.1.5 Control in the control unit "degree"
If the control units are "degree", the following items differ from other control units. (1) Current value address
The current addresses in the control unit "degree" are ring addresses from 0 to 360.
359.99999 359.99999
000
(2) Stroke limit valid/invalid setting The upper/lower limit value of the stroke limit in the control unit "degree" is within the range of 0 to 359.99999 (a) Stroke limit is valid
Set the "lower limit value to upper limit value of the stroke limit" in a clockwise direction to validate the stroke limit value.
315.00000
90.00000
0
Clockwise Area A
Area B
1) If travel range in area A is set, the limit values are as follows:
a) Lower stroke limit value: 315.00000 b) Upper stroke limit value: 90.00000
2) If travel range in area B is set, the limit values are as follows: a) Lower stroke limit lower limit value: 90.00000 b) Upper stroke limit upper limit value: 315.00000
(b) Stroke limit is invalid
Set the "upper stroke limit value" equal to "lower stroke limit value" to invalidate the stroke limit value. It can be controlled regardless the stroke limit settings.
POINTS
(1) Circular interpolation including the axis which set the stroke limit as invalid cannot be executed.
(2) When the upper/lower limit value of the axis which set the stroke limit as valid
are changed, perform the home position return after that. (3) When the stroke limit is set as valid in the incremental data system, perform
the home position return after power supply on.
6 - 10
6 POSITIONING CONTROL
(3) Positioning control
Positioning control method in the control unit "degree" is shown below. (a) Absolute data method (ABS instructions)
Positioning in a near direction to the specified address is performed based on the current value.
(1) Positioning is executed in a clockwise direction to travel from the current value
of 315.00000to 0. (2) Positioning is executed in a counter clockwise direction to travel from the
current value of 0 to 315.00000.
315.00000 315.00000
0 0
0 315.00000315.00000 0
POINTS (1) The positioning direction of absolute data method is set a clockwise/counter
clockwise direction by the setting method of stroke limit range, positioning in the shortest direction may not be possible.
Travel from the current value 0 to 315.00000must be clockwise positioning
if the lower stroke limit value is set to 0and the upper limit value is set to 345.00000.
315.00000
0345.00000
Clockwise positioning
(2) Set the positioning address within the range of 0 to 360.
Use the incremental data method for positioning of one revolution or more.
(b) Incremental data method (INC instructions) Positioning by the specified travel value to the specified direction. The travel direction is set by the sign of the travel value, as follows: 1) Positive travel value ................Clockwise rotation 2) Negative travel value...............Counter clockwise rotation
POINT
Positioning of 360 or more can be executed in the incremental data method.

[Cautions]
(1) The helical interpolation instruction can be used at the both of real/virtual mode.
(2) When the number of pitches is 0 and travel value of linear axis is not "0" is set, operation example is shown below.
Arc center
Linear axis operates so that it may become a position according to this angle.
Circular interpolation path
End point (X1, Y1, Z1)
Start point (X0, Y0, Z0)
Linear axis operation
Condition Operation
Number of pitches is 0 Control on the circular plane. Number of pitches is not 0 Rotation spirally of the number of pitches to linear axis direction.
6 - 57
6 POSITIONING CONTROL
(3) When the travel value of linear axis is "0" is set, it can be controlled.
Condition Operation
Number of pitches is 0 Same control as normal circular interpolation control. (Allowable error range for circular interpolation can be set.)
Number of pitches is not 0 Linear interpolation to linear axis does not executed, circle for the number of pitches is drawn on the circle plane. (Allowable error range for circular interpolation can be set.)
(4) Units for linear axis have not restrictions.
(5) Circular interpolation axis has the following restrictions.
When the unit of one axis is [degree] axis (with stroke range), set another axis also as [degree] axis (without stroke range).
The axis of [degree] unit as without stroke range cannot be set. The axis as without stroke range cannot be set in the virtual mode.
(6) Specified the speed which executes speed change by CHGV instruction during
helical interpolation operation with the combined-speed of circular interpolation axis 2. If speed change is requested by specifying negative speed by CHGV instruction during helical interpolation operation, deceleration starts from the time and it is possible to return to reverse direction at the deceleration completion.
(7) If start point = end point, number of pitches = 1 and travel value of linear axis = 0,
at the only central point-specified circular interpolation, full circle can be drawn. when the address of "start point = end point" is set at the radius-specified helical interpolation or auxiliary point-specified helical interpolation, a minor error (error code [108]) occurs at the start and cannot be start.
(8) When the control unit is [degree] and the stroke limit is invalid, if the helical
interpolation control is executed using absolute data method, positioning in near direction to specified address based on the current value.
(9) Allowable error range for circular interpolation can be set.

ABH , ABH , ABH , ABH Absolute radius-specified helical interpolation control
[Control details] The linear interpolation to other linear axis is executed performing 2 axes circular interpolation from current stop position (X0, Y0, Z0) to specified circular end address (X1, Y1) or linear axis end point address (Z1), and the absolute helical interpolation is executed so that it may become a spiral course. It goes around on the specified circle for the specified number of pitches, the circular interpolation which had remainder specified is executed, and positioning to end address is executed. The radius-specified circle specifies circular interpolation method connected start point and end point at the seeing on the plane for which performs circular interpolation.

REMARK
(Note): "The external CHANGE signal input from external source" is inputted to CHANGE of the Q172LX from external source. When "normally open contact input" is set in the system settings, CHANGE input occurs at the CHANGE signal on, and when "normally closed contact input" is set, CHANGE input occurs at the CHANGE signal off. (Refer to the "Q173HCPU/Q172HCPU Motion controller User's Manual".)
(3) Feed current value processing
The feed current value is as follows by turning feed current value update request command (M3212+20n) on/off at the speed/position switching control start. (a) M3212+20n OFF...... The feed current value is cleared to "0" at the start.
The feed current value is updated from the start (speed control).
The feed current value after stop is as follows:
Feed current value after stop
Travel value during speed
control
Travel value for position
control = +
(b) M3212+20n ON.... The feed current value is not cleared at the start. The feed current value is updated from the start
(speed control). If the feed current value exceeds the stroke limit, a
deceleration stop is executed. The feed current value after stop is as follows:

(3) "Travel value for position control" is less than "deceleration distance"
(a) If the travel value for position control is less than the deceleration distance at controlling speed, deceleration processing starts immediately when CHANGE is input.
(b) The difference between travel value for the deceleration stop and position control is the overrun. At this time, the error detection signal (M2407+20n) turns on and error code [209] is stored in the data register.
(c) The positioning complete signal (M2401+20n) does not turn on.

[Control details]
Start and end of the speed-switching control
Speed-switching control is started and ended using the following instructions: (1) VSTART
Starts the speed-switching control.
(2) VEND Ends the speed-switching control.
Travel value setting to end address/end point
The travel value to end address/end point with the speed-switching control, positioning control method and positioning speed to the end point are set using the following instructions : (1) ABS-1/INC-1
Set 1 axis linear positioning control. The control contents are same as Section 6.2 "1 Axis Linear Positioning Control".
(2) ABS-2/INC-2
Set 2 axes linear interpolation control. The control contents are same as Section 6.3 "2 Axes Linear Interpolation Control".
(3) ABS-3/INC-3
Set 3 axes linear interpolation control. The control contents are same as Section 6.4 "3 Axes Linear Interpolation Control".
Speed-switching point setting
The address (travel value) of the speed-switching point and the positioning speed are set using the following instructions: (1) VABS
Set the speed-switching point using the absolute data method.
(2) VINC Set the speed-switching point using the incremental data method.
POINT The axis which set the speed-switching point (travel value) and positioning speed by 2 or 3 axes linear interpolation control is first set in the "travel value to end address/end point".

6 POSITIONING CONTROL
[Cautions]
(1) The number of control axes cannot be changed during control.
(2) The speed-switching point can be specified the absolute data method (VABS ) and incremental data method (VINC ) by mixed use.
(3) The speed-switching point cannot be specified an address which change in travel
direction. If the travel direction change, the error code [215] is stored in the minor error storage register for each axis and the deceleration stop is performed.
(4) It checks whether to be the end address within the stroke limit range at the start.
If it is positioning to outside the stroke limit range, the error code [106] is stored in the minor error storage register for each axis and operation does not start.
(5) If the travel value between speed-switching points is so short and it shifts to the
next speed-switching point during speed-switching control, the speed-switching does not perform.
(6) If the M-code from the previous point is retained in the point with which M-code is
not specified. [Program]

6.17 Constant-Speed Control
(1) Positioning to the pass point beforehand set by one starting is executed with the specified positioning method and positioning speed.
(2) The positioning method and positioning speed can be changed for each pass
point.
(3) The following parameters is set in the servo program. Pass point Positioning method from any pass point to the next pass point. Positioning speed from any pass point to the next pass point.
(4) Repetition control between any pass points can be performed by using repetition
instructions.
(5) M-codes and torque limit values can be changed at each speed-switching point.
(6) 1 to 4 axes can be controlled. [Procedure to write servo programs]
The method to write the servo programs for constant-speed control is shown below.

(1) The number of control axes cannot be changed during control.
(2) The pass point can be specified the absolute data method (ABS ) and incremental method (INC ) by mixed use.
(3) The pass point can also be specified an address which change in travel direction.
The acceleration processing at a pass point is executed for 1 axis constant-speed. However, the acceleration/deceleration processing at a pass point is not executed for 2 to 4 axes constant-speed, so be careful of the servo error occurrence, etc.
(4) Speed change is possible after the start.
Note the following points at the speed change. (a) The central point-specified circular interpolation is included the constant-
speed control. When the arc path calculated from the start address and central-point address is differ (within the allowable error range for circular interpolation) from the setting end address, if the speed is changed, error compensation (Refer to Section 4.3.3) may not function normally. When the central point-specified circular interpolation as positioning method is used at the constant-speed control, set the start address, central point address and end address becomes arc correctly.

6 POSITIONING CONTROL
(b) The speed switching and change speed by CHGV instruction are executed
toward the same program in the servo program. The lower of the speed change by CHGV instructions and the command speed in the servo program is selected. The speed change by CHGV instructions are executed if the speed is lower than the speed set in the servo program; otherwise the CHGV instructions are not executed. 1) Change speed by CHGV instruction > command speed in the servo
program The command speed in the servo program is selected.

(5) An overrun occurs if the distance remaining to the final positioning point when the final positioning point is detected is less than the deceleration distance at the positioning speed after the start (command speed). The error code [211] (overrun error) is stored in the minor error storage register for each axis.
(6) If positioning to outside the stroke limit range is executed after the start, the error
code [106] is stored in the minor error storage register for each axis and a deceleration stop is executed.
(7) The minimum travel value between constant-speed control pass points is shown
below: Command speed per second (control unit/s) Main cycle [s] < Travel distance [PLS]
6 - 123
6 POSITIONING CONTROL
Example) Main cycle: 20[ms], Command speed: 600[mm/min]
If the command speed (600[mm/min]) is divided by 60, the command speed per second is 10[mm/s], and if the main cycle (20[ms]) is divided by 1000, the main cycle is 0.02[s]. Therefore, the travel distance is as follow.
10[mm/s] 0.02[s] = 0.2[mm] Set the travel distance to more than 0.2[mm].
Positioning speed drops if the distance between pass points is short the minimum travel value.

6 POSITIONING CONTROL
[Cautions]
(1) The helical interpolation specification at pass point for constant-speed control can be used in the both of real and virtual mode.
(2) Specify any 3 axes among 4 controlled axes in the helical interpolation control at
the pass point for 4 axes constant-speed control (CPSTART4).
(3) Command speed at the helical interpolation specified point is controlled with the speed of circumference. Control is the same as before at the point except for the helical interpolation specification. (Both of the linear interpolation-specified point and circular interpolation-specified point are the combined-speed for number of interpolation axes.)
(4) Skip function toward the helical interpolation-specified each point for constant-
speed control is possible. If the absolute-specified helical interpolation is specified to point since the skip signal specified point, set the absolute linear interpolation between them. If it does not set, it may occur an error and stop.
(5) FIN signal wait function toward the helical interpolation specified each pass point
for constant-speed control is possible. M-code outputting signal is outputted to all circular interpolation axes and linear axes. Fin signal can be operated with the both of circular interpolation axes and linear axes.
(6) If negative speed change toward the helical interpolation-specified each pass
point for constant-speed control is executed, it can be returned before 1 point during positioning control.
(7) Speed-switching point-specified flag is effective toward the helical interpolation-
specified each pass point for constant-speed control.

6 POSITIONING CONTROL
6.17.6 Pass point skip function
This function stops positioning to executing point and executes positioning to next point, by setting a skip signal toward each pass point for constant-speed control.
[Data setting] (1) Skip signal devices
The following devices can be specified as skip signal devices. X, Y, M, B, F
[Cautions] (1) When an absolute circular interpolation or absolute helical interpolation is
specified to since point since the skip signal specified point, set the absolute linear interpolation between them. If it does not set, it may occur an error and stop.
(2) If a skip signal is inputted at the end point, a deceleration stop occurs at that point and the program is ended.

6 POSITIONING CONTROL
6.17.7 FIN signal wait function
By selecting the FIN signal wait function and setting a M-code at each executing point, a process end of each executing point is synchronized with the FIN signal, the FIN signal turns ON to OFF and then the next positioning is executed. Turn the FIN signal on/off using the Motion SFC program or PLC program.
[Data setting]
(1) When the FIN signal wait function is selected, the fixed acceleration/deceleration time method is used. Set the acceleration/deceleration time within the range of 1 to 5000 [ms] by "FIN acceleration/deceleration" (selecting item) in the servo program. Indirect setting is also possible by D, W and # devices (1 word).
[Cautions]
(1) If the acceleration/deceleration time is specified outside the setting range, the servo program setting error [13] will occur at the start and it is controlled with the acceleration/deceleration time of 1000[ms].
(2) M-code outputting signal is output to all interpolation axes at the interpolation
control. In this case, turn on the signal for one of the interpolation axes.
(3) When M-code is set at the end point, positioning ends after the FIN signal has turn OFF to ON to OFF.

6 POSITIONING CONTROL
[Cautions]
(1) Number of control axes is 1 axis.
(2) Only the absolute data method (ABS ) is used for positioning control to the pass points.
(3) The speed can be changed during the start.
The changed speed is effective until the stop command is input.
(4) Set the positioning address in the servo program using indirect setting with the word devices D, W and #.
(5) Use only even-numbered devices for indirect setting of positioning address in the
servo program. If odd-numbered devices are used, an error [141] occurs at the start and control does not start.
(6) Positioning speeds can be set in the servo program using indirect setting with the
word devices D, W and #. However, this data is effective only at the position follow-up control start (servo program start) and the speed does not change if the indirect setting are changed during the start.

(3) It can be controlled in the real mode only for axis which "control unit is [degree]
and stroke limit is invalid ("upper stroke limit value" equal to "lower stroke limit value")". If it is started for axis which "control unit is except [degree] or stroke limit is not invalid", a minor error [130] occurs and it does not start. And, if it is started for the virtual servomotor axis in the virtual mode, a servo program setting error [905] occurs and it does not start. (It can be started for real mode axis.)

6 POSITIONING CONTROL
(4) Address setting range is 0 to 35999999 (0 to 359.99999[degree]) in the indirect
setting of positioning address. If it is set outside the setting range, a servo program setting error [n03] occurs and it does not start. Positioning address is input at the program start.
(5) It is controlled in the fixed position stop acceleration/deceleration time set in the servo program at the time of positioning start, speed change request (CHGV) and fixed position stop command ON. The fixed acceleration/deceleration time method is used as an acceleration/deceleration processing in this case.
(6) The setting range of fixed position stop acceleration/deceleration time is 1 to 65536[ms].
(7) In the case of indirect setting, the fixed position stop acceleration/deceleration
time is input in the following timing. Positioning start Speed change request (CHGV) Fixed position stop command ON
(8) When the positioning to specified address completes, the positioning complete
signal (M2401+20n) turns on. It does not turn on at the time of stop by the stop command (M3200+20n)/rapid stop command (M3201+20n). The positioning complete signal (M2401+20n) turns off by turning the complete signal OFF command (M3204+20n) off to on or positioning start.
(9) Speed change can be executed any number of times by the speed change request (CHGV) instruction during operation.

(11) When the fixed position stop command turns on, the command in-position check
starts. When the absolute value of difference between the setting address and feed current value below the "command in-position range" set in the fixed parameter, the command in-position signal (M2403+20n) turns on. The command in-position signal (M2403+20n) turns on by a positioning start.

6.23 Home Position Return
(1) Use the home position return at the power supply ON and other times where confirmation of axis is at the machine home position is required.
(2) The following six methods for home position return are shown below.
Proximity dog type Count type Data set type Dog cradle type Stopper type Limit switch combined type
(3) The home position return data must be set for each axis to execute the home
position return.
(4) Select the optimal home position return method for the system configuration and applications with reference to the following.
Home position return methods Contents Applications
Proximity dog type 1 Home position is zero point of servomotor. When the proximity dog is ON, it cannot be
started.
It is used in the system which can surely pass a zero point from the home position return start to proximity dog ON OFF.
Proximity dog type
Proximity dog type 2 Home position is zero point of servomotor. When the proximity dog is ON, it can be
started.
This method is valid when the stroke range is short and "proximity dog type 1" cannot be used.
Count type 1
Home position is zero point of servomotor. It is used in the system which can surely pass a zero point from the home position return start to point of travel distance set as "travel value after proximity dog ON".
Count type 2 Zero point is not used in the home position
return. This method is used when the proximity dog is
near the stroke end and the stroke range is narrow.
Count type (Note)
Count type 3 Home position is zero point of servomotor. This method is valid when the stroke range is short and "count type 1" cannot be used.
Data set type 1
Home position is command position of Motion CPU.
External input signals such as dog signal are not set in the absolute position system.
This method is valid for the data set independent of a deviation counter value. Data set type
Data set type 2 Home position is real position of servomotor.
External input signals such as dog signal are not set in the absolute position system.
Dog cradle type Home position is zero point of servomotor
immediately after the proximity dog signal ON.
It is easy to set the position of proximity dog, because the proximity dog is set near the position made to the home position.
Stopper type 1 Home position is position which stopped
the machine by the stopper. Proximity dog is used. Stopper type
Stopper type 2 Home position is position which stopped
the machine by the stopper. Proximity dog is not used.
This method is valid to improve home position accuracy in order to make the home position for the position which stopped the machine by the stopper.
Limit switch combined type Home position is zero point of servomotor. Proximity dog is not used. External limit switch is surely used.
It is used in the system that the proximity dog signal cannot be used and only external limit switch can be used.
(Note): If the proximity dog signal of servo amplifier is used, the count type home position return cannot be execute.

POINT A home position return must be made after the servomotor has been rotated more than one revolution to pass the axis through the Z-phase (motor reference position signal). For a proximity dog type or count type home position return, the distance between the point where the home position return program is started and the deceleration stop point before re-travel must be such that the servomotor is rotated more than one revolution to pass the axis through the Z-phase. When a data set type home position return is made in an ABS (absolute position) system, the servomotor must also have been rotated more than one revolution by JOG operation or the like to pass the axis through the Z-phase. (Note) : When "1 : No servomotor Z-phase pass after power ON" is selected in the
"function selection C-4" of servo parameter (expansion setting parameter), even if it does not pass zero point, the home position return can be executed and restrictions are lost.

(5) Operation setting for incompletion of home position return
(a) Operation in selecting "0: Execute servo program" 1) Servo program can be executed even if the home position return request
signal (M2409+20n) is ON.
(b) Operation in selecting "1: Not execute servo program" 1) Servo program cannot be executed if the home position return request
signal (M2409+20n) is ON. However, the servo program can be executed even if the home position return request signal (M2409+20n) is ON in the case of only servo program of home position return instruction (ZERO).
2) At the time of servo program start, when "1: Not execute servo program" is selected in the operation setting for incompletion of home position return and the axis which the home position return request signal (M2409+20n) is ON exists also with one axis, a minor error [121] occurs and the servo program does not start.
3) JOG operation and manual pulse generator operation can be executed regardless of the home position return request signal (M2409+20n) ON/OFF.
4) Same operation is executed regardless of absolute position system or not. When "1: Not execute servo program" is selected in the case of not absolute position system, the home position return request signal (M2409+20n) turns ON at power supply ON or reset of Motion CPU and power supply ON of servo amplifier. Therefore, it must be executed home position return before a servo program start.
5) Same operation is executed in also TEST mode. 6) This setting is valid in the real mode only. Servo program can be
executed for a virtual axis connected to the output axis which the home position return request signal (M2409+20n) is ON.
(6) Indirect setting of home position return data
A part of home position return data can be executed the indirect setting by the word devices (D, W, #) of Motion CPU. (a) Data devices for indirect setting
There are data registers (D), link registers (W) and Motion registers (#) as data devices for indirect setting. (Word devices except data registers, link registers and Motion registers cannot be used.) Usable devices are shown below. (Set the number of words for 2 words as even number.)

(b) Input of home position return
In the indirect setting by the word devices, the specified word device data are read at servo program execution by Motion CPU. Set data to devices for indirect setting and then execute the start request of servo program at home position return.
POINT
(1) Indirect setting of axis cannot be executed using word devices in the servo program.
(2) Take an interlock with start accept flag (M2001 to M2032) not to change until the device data specified for indirect setting. If the device data is changed before starting accept, it may not execute the home position return at the normal value.

6.23.2 Home position return by the proximity dog type 1
(1) Proximity dog type 1 Zero point position after proximity dog ON to OFF is home position in this method. When it does not pass (zero pass signal: M2406+20n OFF) the zero point from home position return start to deceleration stop by proximity dog ON to OFF, an error will occur and home position return is not executed. However, when "1 : Not need to pass motor Z phase after the power supply is switched on" is selected in the "function selection C-4" of servo parameter (expansion setting parameter), if it does not pass zero point from home position return start to deceleration stop by proximity dog ON to OFF, the home position return can be executed.
(2) Home position return by the proximity dog type 1
Operation of home position return by proximity dog type 1 for passing (zero pass signal: M2406+20n ON) the zero point from home position return start to deceleration stop by proximity dog ON to OFF is shown below.

6 POSITIONING CONTROL
(4) Cautions
(a) Keep the proximity dog ON during deceleration from the home position return speed to the creep speed. If the proximity dog turns OFF before deceleration to the creep speed, a deceleration stop is made and the next zero point is set as the home position.
ON
Proximity dog
Setting creep speed
The zero point is passed during deceleration stop by the proximity dog OFF.
Home position return speed
OFF Zero point
Zero point of this range does not become the home position. The next zero point becomes the home position.
(b) The position executed deceleration stop by the proximity dog OFF is near
zero point, a home position discrepancy equivalent to one revolution of the servomotor may occur. Adjust the position of proximity dog OFF, such that the home position return re-travel value becomes half the travel value for one revolution of the servomotor.
OFF ON Proximity dog
If the position executed deceleration stop by the proximity dog OFF is near zero point, the creep speed and deceleration settings may result in a home position discrepancy equivalent to one revolution of the servomotor.
Zero point
POINT When the home position return retry function is not set in the following cases, execute the home position return, after return the axis once to position before the proximity dog ON by the JOG operation, etc. Home position return cannot be executed without returning to position before the proximity dog ON. (1) Home position return with a position after the proximity dog ON to OFF. (2) When the power supply turned OFF to ON after home position return end.
6 - 200
6 POSITIONING CONTROL
(c) When it does not pass (zero pass signal: M2406+20n ON) the zero point
from home position return start to deceleration stop by proximity dog ON to OFF, a minor error "ZCT not set" (error code: 120) will occur, a deceleration stop is made and home position return does not end normally. When a distance between home position return start position and home position is near and a zero point is not passed, select the proximity dog type 2.

6.23.3 Home position return by the proximity dog type 2
(1) Proximity dog type 2 Zero point position after proximity dog ON to OFF is home position in this method. When it passed (zero pass signal: M2406+20n ON) the zero point from home position return start to deceleration stop by proximity dog ON to OFF, operation for "proximity dog type 2" is the same as "proximity dog type 1". (Refer to Section 6.23.2) When it does not pass (zero pass signal: M2406+20n OFF) the zero point from home position return start to deceleration stop by proximity dog ON to OFF, it moves to home position return direction after the servomotor is rotated one revolution to reverse direction and it passed the zero point, and the first zero point position is set as home position after proximity dog ON to OFF.
(2) Home position return by the proximity dog type 2
Operation of home position return by proximity dog type 2 for not passing the zero point from home position return start to deceleration stop by proximity dog ON to OFF is shown below.

1) It travels to preset direction of home position return with the home position return speed. 2) A deceleration is made to the creep speed by the proximity dog ON, after that, it travels
with the creep speed. (If the proximity dog turns OFF during a deceleration, a deceleration stop is made and the operation for 4) starts.)
3) A deceleration stop is made by the proximity dog OFF. 4) After a deceleration stop, it travels for one revolution of servomotor to reverse direction of home position return with the home position return speed. 5) It travels to direction of home position return with the home position return speed, the home position return ends with first zero point
after the proximity dog ON to OFF. (At this time, a deceleration to the creep speed is not
made with the proximity dog OFF to ON . And
if the zero point is not passed because of droop pulses for processing of 4) and 5), a minor error "ZCT not set" (error code: 120) will occur, a deceleration stop is made and the home position return does not end

(4) Cautions
(a) A system which the servomotor can rotate one time or more is required.
(b) When a servomotor stops with specified condition enables and rotates to reverse direction one time after proximity dog ON, make a system for which does not turn OFF the external upper/lower stroke limit.
(c) Keep the proximity dog ON during deceleration from the home position
return speed to the creep speed. If the proximity dog turns OFF before deceleration to the creep speed, a deceleration stop is made and the next zero point is set as the home position.
(d) If home position return is executed in the proximity dog ON, it starts with the
creep speed.
(e) When home position return retry function is not set, if home position return is executed again after home position return completion, a minor error "home position return completion signal is turning ON at the proximity dog type home position return start" (error code: 115) will occur, the home position return is not executed.
(f) When "1 : Not need to pass motor Z phase after the power supply is
switched on" is selected in the "function selection C-4" of servo parameter (expansion setting parameter), even if it does not pass zero point at the servo amplifier power ON, the zero pass signal (M2406+20n) turns ON. This operation is the same as proximity dog type 1.

(1) Count type 1 After the proximity dog ON, the zero point after the specified distance (travel value after proximity dog ON) is home position in this method. (If the proximity dog signal of servo amplifier is used, the count type 1 home position return cannot be executed.) When the zero point is not passed (zero pass signal: M2406+20n OFF) until it travels the distance set in the "travel value after proximity dog ON" from home position return start, an error will occur and home position return is not executed. However, when "1 : Not need to pass motor Z phase after the power supply is switched on" is selected in the "function selection C-4" of servo parameter (expansion setting parameter), if the zero point is not passed until it travels the distance set in the "travel value after proximity dog ON" from home position return start, the home position return can be executed. The travel value after proximity dog ON is set in the home position return data (Refer to Section 6.23.1).

(4) Cautions
(a) Home position return and continuously start of home position return are also possible in the proximity dog ON in the count type 1. When the home position return or continuously start of home position return are executed in the proximity dog ON, the home position return is executed after return the axis once to position of the proximity dog OFF.
(b) When the zero point is not passed (zero pass signal: M2406+20n ON) until it
travels the distance set in the "travel value after proximity dog ON" from home position return start, a minor error "ZCT not set" (error code: 120) will occur, a deceleration stop is made and home position return does not end normally. When a distance between home position return start position and home position is near and a zero point is not passed, select the count type 3.
(c) When the "travel value after proximity dog ON" is less than the deceleration
distance from "home position return speed" to "creep speed", a minor error "an overrun occurred because the setting travel value is less than the deceleration distance at the proximity dog signal input during home position return of count type" (error code: 209) will occur and deceleration stop is made.

It is not related for zero point pass or not pass. (If the proximity dog signal of servo amplifier is used, the count type 2 home position return cannot be executed.) A count type 2 is effective method when a zero point signal cannot be taken. (However, dispersions will occur to the stop position at the home position return compared with the count type 1.)

When the home position return and continuously start of home position return are executed in the proximity dog ON, the home position return is executed after return the axis once to position of the proximity dog OFF.
(b) When the "travel value after proximity dog ON" is less than the deceleration
distance from "home position return speed" to "creep speed", a minor error "an overrun occurred because the setting travel value is less than the deceleration distance at the proximity dog signal input during home position return of count type." (error code: 209) will occur and deceleration stop is made.

(1) Count type 3 After the proximity dog ON, the zero point after the specified distance (travel value after proximity dog ON) is home position in this method. (If the proximity dog signal of servo amplifier is used, the count type 3 home position return cannot be executed.) When the zero point is passed (zero pass signal: M2406+20n ON) during travel of specified distance set in the travel value after proximity dog ON from the home position return start, home position return operation is the same as count type 1. (Refer to Section 6.23.4) When a zero point is not passed (zero pass signal: M2406+20n OFF) during travel of specified distance set in the travel value after proximity dog ON from the home position return start, it rotates one time to reverse direction and passes the zero point, re-travels to home position return direction, and then the first zero point after the specified distance (travel value after proximity dog ON) after proximity dog ON is set as home position. The travel value after proximity dog ON is set in the home position return data (Refer to Section 6.23.1).

(At this time, a deceleration to the creep speed is not made with the proximity dog OFF to ON. And if the zero point is not passed because of droop pulses for processing of 4) and 5), a minor error "ZCT not set" (error code: 120) will occur, a deceleration stop is made and home position return does not end normally. In this case, adjust a position of proximity dog ON.)

(3) Home position return execution
Home position return by the count type 3 is executed using the servo program in Section 6.23.16.
(4) Cautions (a) A system which the servomotor can rotate one time or more is required.
(b) After the proximity dog ON, when a servomotor rotates one time to reverse
direction after stop with travel value set in the "travel value after proximity dog ON", make a system which does not turn OFF the external upper/lower stroke limit.
(c) Home position return and continuously start of home position return are also possible in the proximity dog ON in the count type 3. When the home position return and continuously start of home position return are executed in the proximity dog ON, the home position return is executed after return the axis once to position of the proximity dog OFF.
(d) When the "travel value after proximity dog ON" is less than the deceleration distance from "home position return speed" to "creep speed", a minor error "an overrun occurred because the setting travel value is less than the deceleration distance at the proximity dog signal input during home position return of count type." (error code: 209) will occur and deceleration stop is made.
(e) When "1 : Not need to pass motor Z phase after the power supply is switched on" is selected in the "function selection C-4" of servo parameter (expansion setting parameter), even if it does not pass zero point at the servo amplifier power ON, the zero pass signal (M2406+20n) turns ON.

(3) Home position return execution
Home position return by the data set type 1 is executed using the servo program in Section 6.23.16.
(4) Cautions
(a) A zero point must be passed (zero pass signal: M2406+20n ON) between turning ON the power supply and executing home position return. If home position return is executed without passing a zero point once, "no zero point passed error" occurs. If "no zero point passed error" occurred, perform the home position return again, after reset the error and turn the servomotor at least one revolution by the JOG operation. The zero point passing can be confirmed with the zero pass signal (M2406+20n). However, when "1 : Not need to pass motor Z phase after the power supply is switched on" is selected in the "function selection C-4" of servo parameter (expansion setting parameter), even if it does not pass zero point at the servo amplifier power ON, the home position return is possible because the zero pass signal (M2406+20n) turns ON.
(b) Home position return is started by the data set type 1 when the absolute
position system does not support, it becomes same function as the current value change command.
(c) The home position return data required for the data set type 1 are the home

If home position return is executed without passing a zero point once, "no zero point passed error" occurs. If "no zero point passed error" occurred, perform the home position return again, after reset the error and turn the servomotor at least one revolution by the JOG operation. The zero point passing can be confirmed with the zero pass signal (M2406+20n). However, when "1 : Not need to pass motor Z phase after the power supply is switched on" is selected in the "function selection C-4" of servo parameter (expansion setting parameter), even if it does not pass zero point at the servo amplifier power ON, the home position return is possible because the zero pass signal (M2406+20n) turns ON.

(a) For the axis which executes the home position return by the limit switch combined type, if the external input signal has not set in the system settings, a minor error "the positioning control which use the external input signal was executed for the axis which has not set the external input signal in the system settings" (error code: 142) will occur and home position return is not executed.
(b) When the limit switch reverse to home position return direction is turned ON to OFF, deceleration stop is made, home position return is not completed and a major error "external limit switch detection error" (error code : 1101, 1102) will occur.
(c) Home position return retry function cannot be used in the limit switch combined type.
(d) If the home position return is executed with the limit switch OFF, it is started to reverse direction of home position return with creep speed.
(e) When it does not pass (zero pass signal: M2406+20n ON) the zero point from home position return start to deceleration stop by limit switch OFF, a minor error "ZCT not set" (error code: 120) will occur, a deceleration stop is made and home position return does not end normally. However, when "1 : Not need to pass motor Z phase after the power supply is switched on" is selected in the "function selection C-4" of servo parameter (expansion setting parameter), if the zero point is not passed until from home position return start to deceleration stop by limit switch OFF, the home position return can be executed.

6.23.13 Home position return retry function
When a work has been exceeded home position during positioning control, etc., even if it executes the home position return, depending on the position of work, a work may not travel to home position direction. In this case, a work is normally travelled before the proximity dog by the JOG operation, etc, and the home position return is started again. However, by using the home position return retry function, even if a work is where, the home position return can be executed. Refer to Section 6.23.1(7) for home position return method by using the home position return retry function.
[Data Setting]
When the "home position return retry function" is used, set the following "home position return data" using a peripheral devices. Set the "dwell time at the home position return retry" as required. Set the parameters for every axis.

6.23.15 Condition selection of home position set
A home position return must be made after the servomotor has been rotated more than one revolution to pass the axis through the Z-phase (motor reference position signal) and the zero pass signal (M2406+20n) has been turned ON. When "1 : Not need to pass motor Z phase after the power supply is switched on" is selected in the "function selection C-4, (PC17) Condition selection of home position set" of servo parameter (expansion setting parameter), if it does not pass zero point with the motor rotation after turning the servo amplifier power ON, the zero pass signal (M2406+20n) can be turned ON.
[Data Setting]
Set the following "servo parameter" using a peripheral devices to select the "function selection C-4". Set the servo parameters for every axis.
Table 6.6 Servo parameter (expansion setting parameter)
Items Setting details Setting value Initial value
Function selection C-4 (PC17) Condition selection of home position set
Set the condition selection of home position set in the absolute position system.

0
[Cautions]
(1) When "1 : Not need to pass motor Z phase after the power supply is switched on" is set as the above servo parameter, a restrictions such as "make the home position return after the servomotor is rotated more than one revolution to pass the axis through the Z-phase (motor reference position signal) " is lost.
(2) When "1 : Not need to pass motor Z phase after the power supply is switched on"
is selected in the "function selection C-4" of servo parameter (expansion setting parameter), if it does not pass zero point at the servo amplifier power ON, the zero pass signal (M2406+20n) turns ON.
(3) When the above parameter is changed, turn the servo amplifier power OFF to ON
after resetting or turning power OFF to ON of Multiple CPU system.
CAUTION Do not set the "1 : Not need to pass motor Z phase after the power supply is switched on" for axis which executes the home position return again after it continues traveling the same direction infinitely.

7 AUXILIARY AND APPLIED FUNCTIONS
7. AUXILIARY AND APPLIED FUNCTIONS
This section describes the auxiliary and applied functions for positioning control in the Multiple CPU system.
7.1 M-code Output Function
M-code is a code No. between 0 and 32767 which can be set for every positioning control. During positioning control, these M-codes are read using the Motion SFC program to check the servo program during operation and to command auxiliary operations, such as clamping, drill rotation and tool replacement. (1) Setting of M-codes
M-code can be set using a peripheral device at the creation and correction of the servo program.
(2) Storage of M-code and read timing
(a) M-codes are stored in the M-code storage register of the axis specified with the positioning start completion and specified points (at the speed switching control or constant-speed control). During interpolation control, the M-codes are stored in all axes which perform interpolation control.
(b) When the M-code is read at the positioning start completion, use the positioning start complete signal (M2400+20n) as the reading command.

(3) Resetting of M-codes M-codes can be reset by setting of the M-code output devices to zero. Use this method during positioning control to perform operations unrelated to the servo program, such as when it has been difficult to output the M-code during the previous positioning control. However, M-code is set55 during the speed switching control or constant-speed control, the M-code output of the servo program takes priority.

When the current positioning is stopped by input from external source and the next positioning control is performed, it enables starting of the next positioning control even if the input from external source is on (continuation). There are following tow functions in the function called "Skip". Skip during CP command (Refer to Section "6.17.6 Pass point skip function".)
Skip in which disregards stop command
Usually, although an error [ ] occurs with the servo program start during the STOP signal on, if M3209+20n turns on and the servo program starts, the next servo program starts even if during the STOP signal on.
(1) The procedure for the skip function by the external STOP signal and Motion SFC
program is shown below.
Positioning start using the servo program
Start
Turn on the external STOP signal at the positioning stop
Turn on the external stop input disable at start command (M3209+20n)
Start the positioning using the next servo program after deceleration stop
End
Positioning does not start if the STOP signal, stop command (M3200+20n) or rapid stop command (M3201+20n) turns on.
Turn M3209+20n on to use the skip function. (The external STOP signal becomes invalid at the next positioning start.)
If M3209+20n turns off, the external STOP signal becomes valid, and if the STOP signal is input, the positioning does not start.
Confirm the operation stop with the start accept flag (M2001 to M2032) turns off.

APPENDIX 1 Error Codes Stored Using The Motion CPU
The servo program setting errors and positioning errors are detected in the Motion CPU side.
(1) Servo program setting errors
These are positioning data errors set in the servo program, and it checks at the start of the each servo program. They are errors that occur when the positioning data is specified indirectly. The operations at the error occurrence are shown below. The servo program setting error flag (M9079) turns on. The erroneous servo program is stored in the error program No. storage register
(D9189). The error code is stored in the error item information register (D9190).
(2) Positioning error
(a) Positioning errors occurs at the positioning start or during positioning control. There are minor errors, major errors and servo errors. 1) Minor errors These errors occur in the Motion SFC program or servo
program, and the error codes 1 to 999 are used. Check the error code, and remove the error cause by correcting the Motion SFC program or servo program.
2) Major errors These errors occur in the external input signals or control commands from the Motion SFC program, and the error codes 1000 to 1999 are used. Check the error code, and remove the error cause of the external input signal state or Motion SFC program.
3) Servo errors .. These errors detected in the servo amplifier, and the error codes 2000 to 2999 are used. Check the error code, and remove the error cause of the servo amplifier side.

APPENDIX 1.4 Servo errors
(1) Servo amplifier errors (2000 to 2899) These errors are detected by the servo amplifier, and the error codes are [2000] to [2899]. The servo error detection signal (M2408+20n) turns on at the servo amplifier error occurrence. Eliminate the error cause, reset the servo amplifier error by turning on the servo error reset command (M3208+20n) and perform re-start. (The servo error detection signal does not turn on because the codes [2100] to [2599] are for warnings.) (Note-1): As for the regenerative alarm (error code [2030]) or overload 1 or 2
(error codes [2050], [2051]), the state at the operation is held also for after the protection circuit operation in the servo amplifier. The memory contents are cleared with the external power supply off, but are not cleared by the reset signal.
(Note-2): If resetting by turning off the external power supply is repeated at the occurrence of error code [2030], [2050] or [2051], it may cause devices to be destroyed by overheating. Re-start operation after eliminating the cause of the error certainly.
Details of servo errors are shown in Table 1.12.
CAUTION If a controller, servo amplifier self-diagnosis error occurs, check the points stated in this manual and clear the error.

(2) Inputting device data
Indirect setting device data is inputted by the Motion CPU at the servo program start. Do not change the applicable device before setting to device and start completion. The procedures by start method for setting data to devices and cautions are shown below.
Start method Setting method Notes
Start by the servo program Set data in indirect setting devices.
Start the servo program.
Do not change the indirect setting device before the "positioning start complete signal" of the starting axis turns on.
Set the loop (FOR - NEXT) point data for CPSTART instruction indirectly
Set initial command data in the indirect setting device.
Start using the servo program (or turn the cancel command device on).
Read the value of "data set pointer for constant-speed control" of the start axis, and update the data input by Motion CPU.
Refer to the positioning signal data register "Monitoring data area" for details.

(Note-1): FEED instruction varies greatly depending on the condition (whether other axes are operating or being stopped). (Note-2): This processing time varies depending on the simultaneous start command. Use this time merely for reference. (Note-3): If the servo amplifiers of 9 axes or more are connected to one SSCNET system, it does not support an operation
cycle of 0.4[ms]. 0.8[ms] is used as the real operation cycle, even if 0.4[ms] is set in the system setting.
