1. Outline

This manual describes the DDB (Direct Data Bus) function used to realize data input/output with a CNC while running a program developed with the user PLC ladder language. DDB includes the synchronous type (DDBS) and the asynchronous type (DDBA), but only the asynchronous type will be explained in this manual. DDB is a function that allows the PLC to directly read and write the various data in the CNC. By setting the information required for reading and writing into the buffer and calling out the DDB function, the PLC can set (write) the designated data into the CNC. Generally, the data is read and written in one piece units, but data related to the control axis can be processed for the designated number of axes. Features of this function include that the read data can be referred to in the step immediately following the execution of the DDBA command. This also applies to the written data. (Note that for the parameters, they may not be valid immediately after writing.) This manual is organized in the following manner after the first chapter. Please refer to the required section for use.

Set control data with MOV command, etc.

(Note 1)ACT

(Note 1) The file registers (Rn) and data registers (Dn) in the range usable by the user can be used in the control data buffer of the asynchronous type DDB . The file registers (R) usable by the user are from R4000 to R4499 (not backup) and from R6400 to R7199 (backup).

2.2 Basic format of control data

Rn (Dn) Control signal

Rn+1 (Dn+1) Section No. Rn+2 (Dn+2) Sub-section No.

Rn+4 (Dn+4) Data size

Rn+5 (Dn+5) Axis/part system designation for read/write

Rn+6 (Dn+6) Read/write data (for 1st axis)

Rn+8 (Dn+8) (for 2nd axis)

Rn+10 (Dn+10) (for 3rd axis)

Rn+12 (Dn+12)

(for 4th axis)

: : : Rn+32 (Dn+32)

(for 14th axis)

(Note 1) The part system designation is used when there is a multi-part system specification. (Note 2) Always secure 4 bytes as the buffer for one read/write data item. (Note 3) Always secure the buffer size equivalent to 14 axes (28 words data). (Note 4) For example, if only the 3rd axis is designated, the data for the 3rd axis will be the

read/write data.

2.2.3 Sub-section No. (Rn+2, Rn+3 or Dn+2, Dn+3) (LOW HIGH)

The sub-section No. of the data to be read/written is designated with a binary. Refer to the "4. Sub-section No. List" for details.

2.2.4 Data size (Rn+4 or Dn+4)

The size of the data to be read/written is designated with a binary. 1: 1 byte 2: 2 bytes 4: 4 bytes

(Note) The date size has not been checked, so give an attention to data size when setting.

Part system designation (Note 1)

1st axis 2nd axis 3rd axis 4th axis 5th axis 6th axis

~

(Note 1) The part system designation is used when there is a multi-part system specification. (Note 2) When reading and writing the axis data, if there is no axis designation or if the

designation exceeds the maximum control axes, the alarm "No. of axes illegal" will occur. 2.2.6 Read/write data (Rn+6, Rn+7 or Dn+6, Dn+7) (LOW) (HIGH)

When read is designated, the data designated by the PLC will be output by the CNC. When write is designated, the data to be written will be set by the PLC.

1-byte data 2-byte data 4-byte data

Rn+6 L Rn+6 L Rn+6 L

(Dn+6) H (Dn+6) H (Dn+6) H L

Rn+7 Rn+7 Rn+7 L

(Dn+7) Code expansion (Dn+7) Code expansion (Dn+7) H H

The valid area of the data will differ according to the data size. (Shaded area) When read is designated, a code will be added to the 1-byte and 2-byte data to create a 4-byte data size. Thus, even when reading 1-byte or 2-byte data, 4 bytes are required for the buffer size.

1-10 Maximum spindle speed (Gear 1st step to gear 4th step)

[Data definition] This is a parameter for the maximum spindle speed of each gear step. (This corresponds to the setup parameter, spindle parameter smax1 to 4.) The CNC creates the spindle gear shift command 1 and 2 with this value and the commanded S command. During tapping, the maximum speed will be the spindle tap speed.

[Data unit, range]

The data unit is r/min, and the setting range is 0 to 99999.

[Precaution] After being set (written), this data is valid from the next spindle speed (S) command. However, the clamping operation with the maximum speed will be validated immediately.

1-11 Spindle limit speed (Gear 1st step to gear 4th step)

[Data definition] This parameter is used to calculate the spindle speed (S-analog) data for each gear step. (This corresponds to the setup parameter, spindle parameter slimt 1 to 4.) The CNC determines the corresponding spindle limit speed with the spindle gear selection input (Y ) output from the PLC, and calculates the spindle speed (S-analog) data.

Spindle speed data = x slimt n 100

SOVRSd1d2d3d4

slimt n : Spindle limit speed of corresponding gear step determined with spindle gear selection input. (n: 1~4) Sd1d2d3d4 : Spindle speed (S) command SOVR : Spindle override

1-100 Position switches [1] to [16]

[Data definition]

A software dog switch is established at a designated point of the axis on the machine, and the output signal from this switch is output to the PLC interface when the axis passes over this switch. A maximum of sixteen switches can be set per part system. This switch can be used after the zero point is established. (This corresponds to the setup parameter, position switches axis, dog1 and dog 2.)

The position switch uses the axis, dog1 and dog2 data as one set.

Axis : Name of axis for which switch is established. dog1 : Distance 1 from basic machine coordinate system zero point dog2 : Distance 2 from basic machine coordinate system zero point

The difference of dog1 and dog2 becomes the position switch width.

For relative position compensation set the name of the axis to be actually compensated. In the multi-part system, set "part system No. + axis name". (This corresponds to the setup parameter, machine compensation parameter drcax.)

[Data unit, range]

Set the axis address of X, Y, Z, U, V, W, A, B, or C etc.

[Precaution] This setting is validated immediately after setting (writing). (Note that this is only when the axis movement is stopped.)

3-12 Division point number at reference position

[Data definition] Set the compensation data No. corresponding to the reference point position. The reference point is actually the base so there is no compensation No. Set the number that is decremented by 1. (This corresponds to the setup parameter, machine compensation parameter rdvno.)

[Data unit, range]

The setting range is 4101 to 5124.

[Precaution] This setting is validated immediately after setting (writing). (Note that this is only when the axis movement is stopped.)

27-10 Smoothing status, servo status

[Data definition]

The various servo related information is expressed in bit units. 27-10-0) Ready ON

If the drive unit can be entered the ready ON state, including the ready ON request signal from the CNC, the main circuit will be turned ON. While the main circuit is ON, the ready ON signal will turn ON as the answer signal to the CNC. The conditions for turning OFF are as follows: 1) When the ready ON request signal from the CNC turns OFF. 2) When the CNC enters the emergency stop state. 3) When a servo alarm occurs.

27-10-1) Servo ON

When the above ready ON signal is ON and the servo ON request signal is received from the CNC, if the conditions provide that the servo can be turned ON, the servo ON signal will turn ON (a position loop will be structured). The servo ON signal will remain ON as the answer signal to the CNC while the position loop is structured. The condition for turning OFF is as follows:

1) When in addition to the conditions for the ready ON signal to turn OFF, the servo ON request signal from the CNC turns OFF.

27-10-2) In emergency stop

This is the signal answered by the drive unit when it receives notice that the CNC is in the emergency stop state. E7 will be displayed on the 7-segment display for drive unit diagnosis.

27-10-3) In alarm

This notifies that the drive unit is in the servo OFF state. 27-10-4) Absolute position established

This turns ON when the absolute position has been established. 27-10-5) Z phase passed

This means that the datum point (Z phase) has been passed by the axis movement after the power was turned ON. The servo parameter "SPEC" value in the setup parameters determines which datum point (Z phase) is valid among the points output by detector. The CNC will determine the reference point return position, etc., based on this signal. Once turned ON, this signal remains ON until it is turned OFF.

27-10-6) In-position

This indicates that the difference of the command and the feedback from the detector, or in other words, the position deflection (position loop droop) is within the range designated by the servo parameter "SV024" (in-position width) in the setup parameters. How the CNC operates upon receiving this signal depends on the basic specification parameter "inpos" (in-position check valid) in the setup parameters.

27-10-7) Torque limit This notifies that the motor drive current has been limited. The current limit parameter will follow the ILMT (limit values for both + and directions) in the servo parameters of the setup parameters.

27-10-8) Smoothing 0

The acceleration/deceleration time constant to make the machine movement smooth is applied to the issued step-state command. The circuit onto which the acceleration/deceleration time constant is applied is called the smoothing circuit. Smoothing 0 means that there is no droop amount in that smoothing circuit. (Note 1) This may turn ON when the machine is moving at an extremely low speed. (Note 2) This state is equivalent to when the plus motion (+) signal (MVPn) and the minus motion

(-) signal (MVMn) sent from the CNC to the PLC are both OFF. 27-10-9) Smoothing (+)

This indicates that there is a (+) droop amount (movement in the + direction) in the smoothing circuit described in section 27-10-8). (Note 1) This may turn OFF when the machine is moving at an extremely low speed. (Note 2) This state is equivalent to the plus motion (+) signal (MVPn) sent from the CNC to the

PLC. 27-10-A) Smoothing (-)

This indicates that there is a (-) droop amount (movement in the direction) in the smoothing circuit described in section 27-10-8). (Note 1) This may turn OFF when the machine is moving at an extremely low speed. (Note 2) This state is equivalent to the minus motion (-) signal (MVPn) sent from the CNC to the

PLC. 27-10-C) Hardware OT+ (hardware overtravel)

This indicates that the stroke end (+) signal was input for an axis moving in the (+) direction. Once the conditions are met, the signal will turn ON and the axis will move in the (-) direction. And when the stroke end (+) signal is no longer input, this signal will turn OFF.

27-10-D) Hardware OT (hardware overtravel)

This indicates that the stroke end (-) signal was input for an axis moving in the (-) direction. Once the conditions are met, the signal will turn ON and the axis will move in the (+) direction. And when the stroke end (-) signal is no longer input, this signal will turn OFF.

27-10-E) Near-point dog ON

This turns ON when the reference point return near-point detection signal (dog) for the axis is detected while executing the dog-type reference point return. This turns OFF when the reference point is reached.
