Do not use this product in any applications other than those specified above, especially those which are substantially in- fluential on the public interest or which are expected to have significant influence on human lives or properties.

1. Items related to prevention of electric shocks

2. Items related to prevention of fire

For Safe Use

WARNING

Do not open or remove the front cover while the power is ON or during operation. The high voltage terminals and charged sections are exposed, and this could result in electric shocks.

Do not remove the front cover even when the power is OFF, except for the wiring works or periodic inspec- tions. The inside of the controller and drive unit are charged, and this could result in electric shocks.

Always wait at least 15 minutes after turning the power OFF. Then, check the voltage with a tester, etc., be- fore wiring works, inspections or connecting with peripheral devices. Failure to observe this could result in electric shocks.

Earth ground the controller, drive unit and motor according to the local laws. (In Japan, ground the 200V Series input products with Class C or higher protective grounding and the 400V Series input with Class D or higher protective grounding.)

All wiring works, maintenance and inspections must be carried out by a qualified technician. Failure to ob- serve this could result in electric shocks. Contact your nearby Service Center for replacing parts and ser- vicing.

Wire the controller, drive unit and motor after installation. Failure to observe this could result in electric shocks.

Do not operate the switches with wet hands. Failure to observe this could result in electric shocks.

Do not damage, apply excessive stress, place heavy things on or sandwich the cables. Failure to observe this could result in electric shocks.

Insulate the power lead using a fixed terminal block. Failure to observe this could result in electric shocks.

Completely turn off the externally supplied power used in the system before wiring. Not doing so could re- sult in electric shock or damage to the product.

When turning on the power supply or operating the module after wiring, be sure that the module's terminal covers are correctly attached. Not attaching the terminal cover could result in electric shock.

CAUTION

Install the controller, drive unit, motor and regenerative resistor on non-combustible material. Installation directly on or near combustible materials could result in fires.

If any malfunction in the unit is observed, shut off the power at the units power supply side. Continuous flow of large current could result in fires.

Install an appropriate no fuse breaker (NFB) and contactor (MC) on the power input section of the drive unit and configure the sequence that shuts the power off upon drive units emergency stop or alarm.

When a breaker is shared for multiple power supply units, the breaker may not function upon short-circuit failure in a small capacity unit. Do not share a breaker for multiple units as this is dangerous.

Incorrect wiring and connections could cause the devices to damage or burn.

3. Items related to prevention of bodily injury or property damage

4. Other items Always follow the precautions below as well. Incorrect handling could result in faults, injuries or electric shocks, etc.

(1) Product and manual

(2) Transportation and installation

DANGER

When transporting or installing a built-in IPM spindle or linear servomotor, be careful so that your hand or property is not trapped in the motors or other metal objects. Also keep the devices with low magnetic tol- erance away from the product.

CAUTION

Do not apply voltages to the connectors or terminals other than voltages indicated in the connection and setup manual for the controller or specifications manual for the drive unit. Failure to observe this could cause bursting, damage, etc.

Incorrect connections could cause the devices to rupture or damage, etc. Always connect the cables to the indicated connectors or terminals.

Incorrect polarity (+ -) could cause the devices to rupture or damage, etc.

Persons wearing medical devices, such as pacemakers, must stay away from this unit. The electromagnetic waves could adversely affect the medical devices.

Fins on the rear of the unit, regenerative resistor and motor, etc., may be hot during operation and for a while after the power has been turned OFF. Do not touch or place the parts and cables, etc. close to these sections. Failure to observe this could result in burns.

Do not enter the machines movable range during automatic operation. Keep your hands, feet or face away from the spindle during rotation.

CAUTION

For items described as "Restrictions" or "Usable State" in this manual, the instruction manual issued by the machine tool builder (MTB) takes precedence over this manual.

Items not described in this manual must be interpreted as "not possible"

This manual is written on the assumption that all the applicable functions are included. Some of them, how- ever, may not be available for your NC system. Refer to the specifications issued by the machine tool build- er before use.

Refer to the manuals issued by the machine manufacturer for each machine tool explanation.

Some screens and functions may differ depending on the NC system (or its version), and some functions may not be possible. Please confirm the specifications before use.

Do not connect NC system to the Internet-connected network.

To maintain the safety of the NC system against unauthorized access from external devices via the network, take appropriate measures.

CAUTION

Correctly transport the products according to the mass.

Use motors suspension bolts to transport the motor itself. Do not use it to transport the motor after instal- lation onto the machine.

Do not stack the products exceeding the indicated limit.

Do not hold the cables, shaft or encoder when transporting the motor.

Do not transport the controller or drive unit by suspending or holding the connected wires or cables.

Do not hold the front cover when transporting the unit, or the front cover could come off, causing the unit to drop.

Install on a non-combustible place where the unit's or motor's mass can be withstood according to the in- struction manual.

The motor does not have a complete water-proof (oil-proof) structure. Do not allow oil or water to contact or enter the motor. Prevent the cutting chips from being accumulated on the motor as they easily soak up oil.

When installing the motor facing upwards, take measures on the machine side so that gear oil, etc., will not enter the motor shaft.

Do not remove the encoder from the motor. (The encoder installation screw is treated with sealing.)

Do not allow foreign matters, especially, conductive foreign matters such as screws or metal chips, or com- bustible foreign matters such as oil, to enter the controller, drive unit or motor. Failure to observe this could result in rupture or damage.

Do not get on the product or place heavy objects on it.

Provide prescribed distance between the controller/drive unit and inner surface of the control panel/other devices.

Do not install or operate the controller, drive unit or motor that is damaged or has missing parts.

Take care not to cut hands, etc. with the heat radiating fins or metal edges.

Do not block the intake/outtake ports of the motor with the cooling fan.

Install the controllers display section and operation board section on the spot where cutting oil will not reach.

The controller, drive unit and motor are precision devices, so do not drop or apply thumping vibration and strong impacts on them.

Store and use the units according to the environment conditions indicated in each specifications manual.

When disinfectants or insecticides must be used to treat wood packaging materials, always use methods other than fumigation (for example, apply heat treatment at the minimum wood core temperature of 56 C for a minimum duration of 30 minutes (ISPM No. 15 (2009))).

If products such as units are directly fumigated or packed with fumigated wooden materials, halogen sub- stances (including fluorine, chlorine, bromine and iodine) contained in fumes may contribute to the erosion of the capacitors. When exporting the products, make sure to comply with the laws and regulations of each country.

Do not use the products in conjunction with any components that contain halogenated flame retardants (bromine, etc). Failure to observe this may cause the erosion of the capacitors.

Securely fix the motor to the machine. The motor could come off during operation if insecurely fixed.

Always install the motor with reduction gear in the designated direction. Failure to observe this could result in oil leaks.

Always install a cover, etc., over the shaft so that the rotary section of the motor cannot be touched during motor rotation.

When installing a coupling to the servomotor shaft end, do not apply impacts by hammering, etc. The en- coder could be damaged.

Use a flexible coupling when connecting with a ball screw, etc., and keep the shaft core deviation smaller than the tolerable radial load of the shaft.

Do not use a rigid coupling as an excessive bending load may be applied on the shaft and could cause the shaft to break.

Do not apply a load exceeding the tolerable level onto the motor shaft. The shaft or bearing could be dam- aged.

Before using this product after a long period of storage, please contact the Service Center.

CAUTION

(3) Items related to wiring

Following the UN recommendations, battery units and batteries should be transported based on the inter- national regulations such as those determined by International Civil Aviation Organization (ICAO), Interna- tional Air Transport Association (IATA), International Maritime Organization (IMO) and U.S. Department of Transportation (DOT).

Due to ventilation problems, do not install the base units vertically or horizontally when C80 is mounted on a board, etc.

Install the basic base unit on a flat surface. Unevenness or warping of the surface can apply undue force to printed circuit boards and lead to operation failures.

Avoid fitting basic unit in proximity to vibration sources such as large electromagnetic contractors and no- fuse circuit breakers; fit the unit on a separate panel or at a distance.

To limit the effects of reflected noise and heat, leave 100mm or more clearance to instruments fitted in front of CNC CPU (on the rear of the door). Similarly, leave 50mm or more clearance between instruments and the left and right sides of the basic base unit.

CAUTION

Correctly wire this product. Failure to observe this could result in motor runaway, etc.

Incorrect connections could cause devices to damage. Connect the cables to designated connectors.

Do not install a phase advancing capacitor, surge absorber or radio noise filter on the output side of the drive unit.

Correctly connect the output side (terminal U, V, W). The motor will not run properly if incorrectly connect- ed.

Always install an AC reactor per each power supply unit.

Always install an appropriate breaker per each power supply unit. A breaker cannot be shared for multiple power supply units.

Do not directly connect a commercial power supply to the motor. Failure to observe this could result in faults.

When using an inductive load such as relays, always connect a diode in parallel to the load as a noise countermeasure.

When using a capacitive load such as a lamp, always connect a protective resistor serially to the load to suppress rush currents.

Do not mistake the direction of the surge absorption diode to be installed on the DC relay for the control output signal. If mistaken, the signal will not be output due to fault in the drive unit, and consequently the protective circuit, such as emergency stop, could be disabled.

Do not connect or disconnect the connection cables between each unit while the power is ON.

Do not connect or disconnect the PCBs while the power is ON.

Do not pull the cables when connecting/disconnecting them.

Securely tighten the cable connector fixing screw or fixing mechanism. The motor could come off during operation if insecurely fixed.

Always treat the shield cables indicated in the Connection Manual with grounding measures such as cable clamps.

Separate the signal wire from the drive line or power line when wiring.

Carry out wiring so that there is no possibility of short circuit between wires, nor of dangerous state.

Use wires and cables whose wire diameter, heat resistance level and bending capacity are compatible with the system.

Ground the device according to the requirements of the country where the device is to be used.

Wire the heat radiating fins and wires so that they do not contact.

When using the RS-232C device as a peripheral device, caution must be paid for connector connection/dis- connection. Always use a double-OFF type AC power supply switch on the device side, and connect/dis- connect the connector with the AC power supply on the device side OFF.

Using a stabilized power supply without overcurrent protection may cause the unit's failure due to miswir- ing of 24V.

12V, 5V, and 3.3V output from connectors are to supply the power for dedicated peripheral devices. Do not use for other equipment to supply the power since we do not guarantee the NC operation by voltage down or noise sneaking.

When using an inductive load such as a relay, always connect a diode in parallel to the load to prevent a counter-electromotive force.

When the rush current exceeds the maximum output current, always connect a protective resistor serially to the load to suppress rush currents.

The wires from the surge absorber should be connected without extensions.

Be sure to ground the earth terminal FG and LG with Class D or higher grounding (Ground resistance: 100 or less). Otherwise it may cause electric shock or operation failure.

When wiring in the unit, be sure that it is done correctly by checking the product's rated voltage and the terminal layout. Connecting a power supply that is different from the rating or incorrectly wiring the product could result in fire or damage.

External connections shall be crimped or pressure welded with the specified tools, or correctly soldered. Imperfect connections could result in short circuit, fire, or operation failure.

Tighten the terminal screws within the specified torque range. If the terminal screws are loose, it could re- sult in short circuit, fire, or operation failure. Tightening the terminal screws too far may cause damages to the screws and/or the module, resulting in drop, short circuit, or operation failure.

Be sure there are no foreign matters such as sawdust or wiring debris inside the module. Such debris could cause fire, damage, or operation failure.

The module has an ingress prevention label on its top to prevent foreign matter, such as wiring debris, from entering the module during wiring. Do not remove this label during wiring. Before starting system opera- tion, be sure to remove this label because of heat dissipation.

When connecting to a personal computer and a unit with the USB interface, an electric shock or a unit fail- ure may occur. It depends on the type of computer to be connected, or the use environment. Operate these correctly according to the manual of a unit and a personal computer. Observe the following cautions when a personal computer in an AC power supply is used. (1) For a personal computer that uses a 3-pin power plug or power plug with a ground lead type, make sure

to use a plug socket including a ground input electrode or ground the earth lead, respectively. And, ensure to ground a personal computer and a unit with Class D or higher grounding (Ground resis- tance: 100 or less).

(2) For a personal computer that uses a 2-pin power plug without ground lead, make sure to connect the unit to the personal computer according to the following procedures. And, it is recommended to supply the same power supply line to a personal computer and the unit. (a) Pull out the power plug of the personal computer from the AC outlet. (b) Confirm that the power plug of the personal computer has been pulled out from the AC outlet, and

connect USB cables, the extension cable or the bus connection cable of a GOT. (c) Insert the power plug of the personal computer into the AC outlet.

(4) Set up

(5) Operation and adjustments

WARNING

Do not cancel the emergency stop before confirming the basic operation.

Always set the stored stroke limit. Failure to set this could result in collision with the machine end.

CAUTION

If the battery low warning is issued, save the machining programs, tool data and parameters in an input/ output device, and then replace the battery. When the battery alarm is issued, the machining programs, tool data and parameters may be destroyed. Reload the data after replacing the battery.

Do not adjust the spindle when possible risks associated with adjustment procedures are not thoroughly taken into consideration.

Be careful when touching spindle's rotating section, or your hand may be caught in or cut.

It is dangerous to restore the backup data of other machine when the absolute position is established be- cause the zero point will be established with the absolute position of the linear axis rewritten, thus the zero point position is off the right position. Initialize the zero point again.

Restoration by SRAM data is available only if the rotary axis motor has not rotated in a same direction 30,000 times or more since the acquisition of the data. Otherwise, the zero point of the rotary axis will change by turning the power OFF and ON after writing the SRAM data, which will cause danger. Make sure the zero point is not off the right position. The use of this method should be limited to when necessary, such as when replacing an NC unit, and requires enough safety confirmation before executing.

CAUTION

If the operation start position is set from a block in the program and the program is started, the program before the set block is not executed. Please confirm that G and F modal and coordinate values are appro- priate. If there are coordinate system shift commands or M, S, T and B commands before the block set as the start position, carry out the required commands using the MDI, etc. If the program is run from the set block without carrying out these operations, there is a danger of interference with the machine or of ma- chine operation at an unexpected speed, which may result in breakage of tools or machine tool or may cause damage to the operators.

Under the constant surface speed control (during G96 modal), if the axis targeted for the constant surface speed control moves toward the spindle center, the spindle rotation speed will increase and may exceed the allowable speed of the workpiece or chuck, etc. In this case, the workpiece, etc. may jump out during machining, which may result in breakage of tools or machine tool or may cause damage to the operators.

Check and adjust programs and each parameter before starting operation. Failure to observe this could re- sult in unpredictable operations depending on the machine.

Do not make drastic adjustments or changes as the operation could become unstable.

In the explanation on bits, set all bits not used, including blank bits, to "0".

(6) Usage

CAUTION

Use C80 in an environment that meets the general specifications contained in "C80 Series Connection and Setup Manual". Using C80 in an environment outside the range of the general specifications could result in electric shock, fire, operation failure, and damage to or deterioration of the product.

When mounting the module, be sure to insert the module fixing hook on the module's bottom into the mod- ule fixing hole on the base unit. Incorrect mounting could cause an operation failure or a damage/drop of the unit.

Hold down the module loading lever at the module bottom and securely insert the fixing hook into the fixing hole in the base unit. Install the module with the module fixing hole as a supporting point. Incorrect mount- ing could cause an operation failure or a damage/drop of the unit.

Be sure to fix all the modules with screws to prevent them from dropping. The fixing screws (M3 x 12) are to be prepared by user.

Tighten the screw in the specified torque range. Under tightening may cause a drop, short circuit or oper- ation failure. Over tightening may cause a drop, short circuit or operation failure due to damage to the screw or module.

Be sure to install the extension cable to connectors of the basic base unit correctly. After installation, check them for looseness. Poor connections could cause an input or output failure.

Completely turn off the externally supplied power used in the system before installation or removing the module. Not doing so could result in electric shock or damage to the product.

Do not install/remove the module on to/from base unit or terminal block more than 50 times, after the first use of the product. Mounting/dismounting over 50 times may cause an operation failure.

Do not directly touch the module's conductive parts or electronic parts. Touching these parts could cause an operation failure or give damage to the module.

Do not touch the heat radiating fins of CNC CPU module 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. Remove the mod- ules with close attention.

When removing the unit, always remove the fixing screws and then take the fixing hook out from the fixing hole. Incorrect removal will damage the module fixing hook.

When the module fixing screws are used, remove the screws first and module from the base unit. Failure to do so may damage the module.

The module surface temperature may be high immediately after power-off. When the module is removed, pay attention to the burn injury.

Install an external emergency stop circuit so that the operation can be stopped and the power turns OFF immediately when unforeseen situation occurs. A contactor, etc., is required in addition to the shutoff func- tion mounted in the controller.

Turn OFF the power immediately if any smoke, abnormal noise or odor is generated from the controller, drive unit or motor.

Only a qualified technician may disassemble or repair this product.

Do not alter.

The metal part becomes the high temperature.

Use a noise filter, etc. to reduce the effect of electromagnetic disturbances in the case where electromag- netic disturbances could adversely affect the electronic devices used near the drive unit.

Use the drive unit, motor and each regenerative resistor with the designated combination. Failure to ob- serve this could result in fires or faults.

The combination of the motor and drive unit that can be used is determined. Be sure to check the models of motor and drive unit before test operation.

The brakes (electromagnetic brakes) mounted in the servomotor are used for the purpose of holding, and must not be used for normal braking. Also, do not run the motor with the motor brake applied. Motor brake is used for the purpose of holding.

For the system running via a timing belt, install a brake on the machine side so that safety can be ensured.

Be sure to confirm SERVO OFF (or READY OFF) when applying the electromagnetic brake. Also, be sure to confirm SERVO ON prior to releasing the brake.

When using the DC OFF type electromagnetic brake, be sure to install a surge absorber on the brake termi- nal.

Do not connect or disconnect the cannon plug while the electromagnetic brakes power is ON. The cannon plug pins could be damaged by sparks.

After changing programs/parameters, or after maintenance/inspection, always carry out a test operation be- fore starting actual operation.

Use the power that are complied with the power specification conditions (input voltage, input frequency, tolerable time for instantaneous power interruption) indicated in each specifications manual.

When making encoder cables, do not mistake connection. Failure to observe this could result in malfunc- tion, runaway or fire.

CAUTION

Use a motor with electromagnetic brakes or establish an external brake mechanism for the purpose of holding; this serves as counter- measures for possible hazardous situation caused by power failure or product fault.

Use a double circuit structure for the electro- magnetic brake's operation circuit so that the brakes will activate even when the external emergency stop signal is issued.

The machine could suddenly restart when the power is restored after an instantaneous power failure, so stay away from the machine. (Design the machine so that the operator safety can be ensured even if the machine restarts.)

To secure the absolute position, do not shut off the servo drive units control power supply when its battery voltage drops (warning 9F) in the servo drive unit side.

If the battery voltage drop warning alarm occurs in the controller side, make sure to back up the machining programs, tool data and parameters, etc. with the input/output device before replacing the battery. Depend- ing on the level of voltage drop, memory loss could have happened. In that case, reload all the data backed up before the alarm occurrence.

(8) Maintenance, inspection and part replacement

CAUTION

Periodically back up the programs, tool data and parameters to avoid potential data loss. Also, back up those data before maintenance and inspections.

The electrolytic capacitors capacity will drop due to deterioration. To prevent secondary damage due to capacitor's faults, Mitsubishi recommends the electrolytic capacitor to be replaced approx. every five years even when used in a normal environment. Contact the Service Center for replacements.

Never perform a megger test (measure the insulation resistance) of the drive unit. Failure to observe this could lead to faults.

Do not replace parts or devices while the power is ON.

Do not short-circuit, charge, overheat, incinerate or disassemble the battery.

Be careful not to break the heat radiating fins during maintenance or replacement.

Perform the daily and periodic inspections according to the maintenance manual.

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 controller or servo amplifier on metal that may cause a power leakage or wood, plastic or vinyl that may cause static electricity buildup.

When replacing the controller or servo amplifier, always set the new unit settings correctly.

After maintenance and inspections are completed, confirm that the position detection of the absolute posi- tion detector function is correct.

The electrolytic capacitor will generate gas during a fault, so do not place your face near the controller or servo amplifier.

If an error occurs in the self diagnosis of the controller or servo amplifier, confirm the check details accord- ing to the instruction manual, and restore the operation.

If an error occurs, remove the cause, secure the safety and then resume operation after alarm release.

The unit may suddenly restart after a power failure is restored, so do not go near the machine. (Design the machine so that the operator safety can be ensured even if the machine restarts.)

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.

(9) Disposal

(10) General precautions

CAUTION

Take the batteries, etc. off from the controller, drive unit and motor, and dispose of them as general indus- trial wastes.

3.2 Durable Parts

A guide to the part replacement cycle is shown below. Note that these will differ according to the working conditions or en-

vironmental conditions, so replace the parts if any abnormality is found. Contact Mitsubishi branch or your dealer for repairs

or part replacements.

[MDS-EM/EMH Series]

(1) Power smoothing capacitor:

The characteristics of the power smoothing capacitor will deteriorate due to the effect of ripple currents, etc. The ca- pacitor life is greatly affected by the ambient temperature and working conditions. However, when used continuously in a normal air-conditioned environment, (ambient temperature is an average of 40C or less) the service life will be ten years.

(2) Relays:

Contact faults will occur due to contact wear caused by the switching current. The service life will be reached after 100,000 cumulative switches (switching life) although this will differ according to the power capacity.

(3) Servo motor bearings:

The motor bearings should be replaced after 20,000 to 30,000 hours of rated load operation at the rated speed. This will be affected by the operation state, but the bearings must be replaced when any abnormal noise or vibration is found in the inspections.

(4) Servo motor oil seal, V-ring:

These parts should be replaced after 5,000 hours of operation at the rated speed. This will be affected by the operation state, but these parts must be replaced if oil leaks, etc., are found in the inspections.

stored in the controller. However, carry out a backup of the whole system before replacement as a precautionary measure.

The power for keeping the encoders position data of an absolute position system is supplied from the battery connected

to the drive unit. Keep the power ON once for 30 minutes or more if possible, and make sure to complete the replacement

within 60 minutes after charging the encoders capacitor.

CAUTION 1. Correctly transport the product according to its weight. Failure to observe this could result in injury.

2. Do not stack the product above the indicated limit.

3. Installation directly on or near combustible materials could result in fires.

4. Install the unit in a place which can withstand its weight.

5. Do not get on or place heavy objects on the unit. Failure to observe this could result in injury.

6. Always use the unit within the designated environment condition range.

7. Do not allow conductive foreign matter such as screws or metal chips, or combustible foreign matter such as oil

enter the servo drive or servo motor.

8. Do not block the intake or exhaust ports of the servo drive of servo motor. Failure to observe this could result in

faults.

9. The servo drive and servo motor are precision devices. Do not drop them or apply strong impacts.

10. Do not install or operate a servo drive or servo motor which is damaged or missing parts.

11. When the unit has been stored for a long time, contact the Service Center.

When this screen is first selected, the respective 16-byte amounts of input/output data are displayed from device "X0000"

on the left display area, and from device "Y0000" on the right side.

This screen constantly monitors and displays the PLC signal statuses. Consequently, when signals are changed in the PLC,

the display is changed according to the changes.

Note that because time differences occur between the PLC signal change and the signal display, there may be a delay in

the display. The machine may also not be able to correspond to extremely brief signal changes.

(1) When setting the device No., an error will occur if a number exceeding the specifications or an illegal address is set.

(2) The input/output signals of X, Y, R, and ZR are the same for all projects.

4.9.2 Safety Observation Screen (Signal Monitor)

The signal monitor screen displays the safety PLC signal status. The safety PLC signal displays both of the duplex PLC

signals to identify the incongruous state. With the initial display, the input/output signal status from the device "X0000" is

displayed on the left side and the input/output signals from the device "Y0000" is displayed on the right side.

Note that because time differences occur between the PLC signal change and the signal display, there may be a delay in

the display. The machine may also not be able to correspond to extremely brief signal changes.

88IB-1501454-D

5Troubleshooting If trouble occurs during operation, the accurate cause must be found so that adequate measures can be taken. Perform the

following checks for this.

5.1 Troubleshooting

Confirm "when", "when doing what", "what kind of trouble" and "how frequently" the trouble occurred. Also check how many

years the machine has been operated, and how many hours a day it is used.

(1) General confirmation items

MTB and type of machine

(2) When?

What time did the trouble occur?

How long had passed after the power was turned ON?

(3) What kind of trouble?

What was displayed on the Alarm Diagnosis screen of the display unit? Display the Alarm Diagnosis screen, and check the alarm details.

What was displayed for the machine sequence alarm?

(4) What were you doing when this occurred?

What was the NC operation mode? During automatic operation: Program No., sequence No. and program details when the trouble occurred. During manual operation: manual operation

What was the operation procedure?

What were the previous and next steps?

What screen is displayed on the display unit of MTB?

What is the state of the peripheral devices?

Did the trouble occur during input/output operations?

What was the machine side state?

Did the trouble occur while replacing the tools?

Did hunting occur in the control axis?

(5) How frequently does the trouble occur? If the trouble occurs infrequently or if it occurs during the operation of another machine, the cause may be an error in the power voltage or the noise, etc. Check whether the power voltage is normal (does it drop momentarily when other machines are operating?), and whether noise measures have been taken.

How frequently does the trouble occur in a day? (Times/day)

Were the peripheral devices operating?

Check whether the same trouble is repeated during the same operation. (Repeatability)

Check whether the same trouble occurs when the conditions are changed.

Does the trouble occur during a specific mode?

What is the frequency in the same workpiece?

What is the ambient temperature? (Was there a sudden change in the temperature?)

Is there any contact defect or insulation defect in the cables? (Is there any oil or cutting oil splattered onto the cables?)

C80 Series Maintenance Manual

5 Troubleshooting

89 IB-1501454-D

5.1.1 Possible Causes of Trouble

The most common cause is a cable contact defect and wire breakage defect.

Is the connection correct?

Are the cables bent or stepped on?

Are the joints of the cables and connectors deteriorated?

Was a continuity test done on the cables?

Is any of the terminal block or connector screws loosen?

Is there any oil or cutting oil splattered onto the cables?

Was a cable disconnected while the power was ON?

Is any cable overheated?

Often trouble occurs due to fluctuation in the power voltage or noise from the communication cable.

Is the power voltage always correct?

Is the power frequency always correct?

Does the voltage fluctuate depending on the time?

Does the voltage drop momentarily when a peripheral device starts operation?

Was there an instantaneous power failure before the trouble?

Have measures against noise been taken for each unit?

Are the communication and power system cables separated and laid?

Is the communication cable shield sufficient?

The trouble may also occur due to sudden temperature changes or vibration and impact, although this is rare.

Are the ambient temperature and humidity adequate?

Is the fan in the panel where the unit is stored rotating?

Is the panel fixed on a flat and stable floor with little vibration?

7.2 Loss and Restoration of Absolute Position Data

Any of the followings may result in the loss of absolute position data.

Changing a parameter related to absolute position

Writing a parameter which was acquired when the zero point was in a different position

SRAM clear of NC

Failure in NC absolute position data

Low battery or uninstallation of the battery of servo drive

Disconnection of detector cable of servo drive

The absolute position data can be restored by backup/restoration function or SRAM data.

(1) Execute "Restore" by backup/restoration function. For details, refer to "8 Appx.2: Data Backup and Restoration".

(2) Turn the NC OFF and ON.

(1) Restoration with the GOTs backup/restoration function restores the linear axis, but not the rotary axis. An initialization of the absolute position of the rotary axis must be performed. The same restoration as the backup/restoration function can be performed by writing the parameter (ALL.PRM).

Restoration by SRAM data

CAUTION Restoration by SRAM data is available only if the rotary axis motor has not rotated in a same direction 30,000 times or more since the acquisition of the data. Otherwise, the zero point of the rotary axis will change by turning the power OFF and ON after writing the SRAM data, which will cause danger. Make sure the zero point is not off the right position. The use of this method should be limited to when necessary, such as when replacing an NC unit, and requires enough safety confirmation before executing.

8Appx.2: Data Backup and Restoration Using the backup/restoration function of the GOT, the data of the NC memory can be backed up in the external device.

Also, the data can be restored from the external device to the NC memory.

This section explains the procedures to backup/restore the data using the front-side USB drive of the GOT.

The target data for the backup/restoration are as follows:

(*1) When the parameter "#1481 Enable S-safety" (Enable smart safety observation) is set to "1", and when restoring the

safety parameters and the safety ladders, release the safety password with the parameter "#51013 SF_PSWD". If the

safety password is not released, these files will not be restored (the restoration will be skipped). When the safety pass-

word of the CNC does not match that of the target file for the restoration, an error will occur during the restoration even

though the safety password has been released.

(*2) This file is valid when the specification of program memory capacity is 1000kB[2560m] or 2000kB[5120m].

(1) Make sure to complete the editing of the machining program or the data setting operation before performing the backup/ restoration.

(2) When the parameter "#1391 User level protect" (Enable Data protection by user's level) is set to "1", release the pro- tection before operating the backup/restoration.

110IB-1501454-D

9Appx.3: Outputting the Error Code This function is to output the information of alarm which is occurring in the CNC CPU. The information is output in the form

of 4-digit hexadecimal error code.

The uniform 4-digit codes express all the alarms.

The error codes are output to the PLC I/F. Thus they can be acquired through a sequence program.

The error codes are displayed on the dot matrix on the front panel of the CNC CPU module.

If you perform CNC CPU module diagnosis using "GX Works3", an engineering tool for PLC, these error codes can be dis-

played along with the details for those error codes.

9.1 PLC Interface

[Function]

This signal outputs the alarm occurring in NCCPU with a code in four hexadecimal digits.

[Operation]

Each part system has the R register that stores one set of error code.

The register in which no errors are stored is set to "0".

The error code which is common for part systems is stored in the 1st part system.

9.2 Classification of the Error Code

The error codes are classified as shown in the table below:

The major error stops the operations of all the CPUs including the CPU No.1.

The moderate error requires the setting which does not stop the operation. When setting the system parameters for the

CPU No.1, go to [Multiple CPU Setting] - [Operation Mode Setting] and make sure to set the stop setting for CNC CPU as

"Major: All Station Stop, Moderate: All Station Continue". If the setting is different, a "multi-CPU error" will occur.

9.4 Dot Matrix Display on the Front of the Module

The below shows the appearance of the CNC CPU module.

The dot matrix displays the state of battery alarm as priority as shown below.

When no alarm is occurring, the dot matrix displays the normal state (RUN).

When no battery alarm is occurring but some sort of alarm occurs, the display of the dot matrix changes from the normal

to the alarm display.

In the state of alarm display, the alarm is displayed in the form of error code as specified in "9.4.1 The Specifications of

String Displayed at the Time of Alarm Display".

The string is displayed shifting from right to left in the dot matrix.

Even if the alarm changes while displaying, the content will not be updated until the string is displayed to the end.

9.4.1 The Specifications of String Displayed at the Time of Alarm Display

(1) The string starts with "ALM".

(2) It displays the error codes from the 1st part system in order. The part system number is displayed at the beginning to- gether with $ symbol.

(3) When multiple alarms occur in one part system, the error codes will be displayed in order of priority. Up to 5 error codes are displayed in one part system.

(4) The alarms which are common for all the part systems are displayed in the 1st part system. The alarms which are com- mon for all the part systems will be displayed with a higher priority.

Display example

When the alarms 1C37 and 1266 are occurring in the 1st part system, and 3062 in the 2nd part system, the indication

is as follows:
