xix

CAUTION

NOTICE

 Wait for at least six minutes after turning OFF the power supply (with a SERVOPACK for a 100-

VAC power supply input, wait for at least nine minutes) and then make sure that the CHARGE indicator is not lit before starting wiring or inspection work. Do not touch the power supply terminals while the CHARGE lamp is lit after turning OFF the power supply because high voltage may still remain in the SERVOPACK.

There is a risk of electric shock.

 Observe the precautions and instructions for wiring and trial operation precisely as described in

this document.

Failures caused by incorrect wiring or incorrect voltage application in the brake circuit may cause the SERVOPACK to fail, damage the equipment, or cause an accident resulting in death or injury.

 Check the wiring to be sure it has been performed correctly.

Connectors and pin layouts are sometimes different for different models. Always confirm the pin layouts in technical documents for your model before operation.

There is a risk of failure or malfunction.

 Connect wires to power supply terminals and motor connection terminals securely with the

specified methods and tightening torque.

Insufficient tightening may cause wires and terminal blocks to generate heat due to faulty contact, possibly resulting in fire.

 Use shielded twisted-pair cables or screened unshielded multi-twisted-pair cables for I/O Sig-

nal Cables and Encoder Cables.

 Observe the following precautions when wiring the SERVOPACK’s main circuit terminals.

• Turn ON the power supply to the SERVOPACK only after all wiring, including the main circuit terminals, has been completed.

• If a connector is used for the main circuit terminals, remove the main circuit connector from the SERVOPACK before you wire it.

• Insert only one wire per insertion hole in the main circuit terminals.

• When you insert a wire, make sure that the conductor wire (e.g., whiskers) does not come into con-

tact with adjacent wires.

 Install molded-case circuit breakers and other safety measures to provide protection against

short circuits in external wiring.

There is a risk of fire or failure.

 Whenever possible, use the Cables specified by Yaskawa.

If you use any other cables, confirm the rated current and application environment of your model and use the wiring materials specified by Yaskawa or equivalent materials.

 Securely tighten cable connector screws and lock mechanisms.

Insufficient tightening may result in cable connectors falling off during operation.

 Do not bundle power lines (e.g., the Main Circuit Cable) and low-current lines (e.g., the I/O Sig-

nal Cables or Encoder Cables) together or run them through the same duct. If you do not place power lines and low-current lines in separate ducts, separate them by at least 30 cm.

If the cables are too close to each other, malfunctions may occur due to noise affecting the low-current lines.

 Install a battery at either the host controller or on the Encoder Cable.

If you install batteries both at the host controller and on the Encoder Cable at the same time, you will create a loop circuit between the batteries, resulting in a risk of damage or burning.

 When connecting a battery, connect the polarity correctly.

There is a risk of battery rupture or encoder failure.

 Operation Precautions

WARNING

CAUTION

 Before starting operation with a machine connected, change the settings of the switches and

parameters to match the machine.

Unexpected machine operation, failure, or personal injury may occur if operation is started before appropriate settings are made.

 Do not radically change the settings of the parameters.

There is a risk of unstable operation, machine damage, or injury.

 Install limit switches or stoppers at the ends of the moving parts of the machine to prevent

unexpected accidents.

There is a risk of machine damage or injury.

 For trial operation, securely mount the Servomotor and disconnect it from the machine.

There is a risk of injury.

 Forcing the motor to stop for overtravel is disabled when the Jog (Fn002), Origin Search

(Fn003), or Easy FFT (Fn206) utility function is executed. Take necessary precautions.

There is a risk of machine damage or injury.

 When an alarm occurs, the Servomotor will coast to a stop or stop with the dynamic brake

according to the SERVOPACK hardware option specifications and settings. The coasting distance will change with the moment of inertia of the load and the resistance of the external dynamic brake resistor. Check the coasting distance during trial operation and implement suitable safety measures on the machine.

 Do not enter the machine’s range of motion during operation.

There is a risk of injury.

 Do not touch the moving parts of the Servomotor or machine during operation.

There is a risk of injury.

 Design the system to ensure safety even when problems, such as broken signal lines, occur.

For example, the P-OT and N-OT signals are set in the default settings to operate on the safe side if a signal line breaks. Do not change the polarity of this type of signal.

 When overtravel occurs, the power supply to the motor is turned OFF and the brake is released.

If you use the Servomotor to drive a vertical load, set the Servomotor to enter a zero-clamped state after the Servomotor stops. Also, install safety devices (such as an external brake or counterweight) to prevent the moving parts of the machine from falling.

 Always turn OFF the servo before you turn OFF the power supply. If you turn OFF the main cir-

cuit power supply or control power supply during operation before you turn OFF the servo, the Servomotor will stop as follows:

• If you turn OFF the main circuit power supply during operation without turning OFF the servo, the Servomotor will stop abruptly with the dynamic brake.

• If you turn OFF the control power supply without turning OFF the servo, the stopping method that is used by the Servomotor depends on the model of the SERVOPACK. For details, refer to the manual for the SERVOPACK.

• If you use a SERVOPACK that supports the dynamic brake hardware option specifications, the Servomotor stopping methods will be different from the stopping methods used without dynamic brake hardware option specifications or for other hardware option specifications.

 Do not use the dynamic brake for any application other than an emergency stop.

There is a risk of failure due to rapid deterioration of elements in the SERVOPACK and the risk of unexpected operation, machine damage, burning, or injury.

NOTICE

DANGER

WARNING

CAUTION

NOTICE

 When you adjust the gain during system commissioning, use a measuring instrument to monitor

the torque waveform and speed waveform and confirm that there is no vibration.

If a high gain causes vibration, the Servomotor will be damaged quickly.

 Do not frequently turn the power supply ON and OFF. After you have started actual operation,

allow at least one hour between turning the power supply ON and OFF (as a guideline). Do not use the product in applications that require the power supply to be turned ON and OFF frequently.

The elements in the SERVOPACK will deteriorate quickly.

 An alarm or warning may occur if communications are performed with the host controller while

the SigmaWin+ or Digital Operator is operating.

If an alarm or warning occurs, it may interrupt the current process and stop the system.

 After you complete trial operation of the machine and facilities, use the SigmaWin+ to back up

the settings of the SERVOPACK parameters. You can use them to reset the parameters after SERVOPACK replacement.

If you do not copy backed up parameter settings, normal operation may not be possible after a faulty SERVOPACK is replaced, possibly resulting in machine or equipment damage.

 Maintenance and Inspection Precautions

 Do not change any wiring while power is being supplied.

There is a risk of electric shock or injury.

 Wiring and inspections must be performed only by qualified engineers.

There is a risk of electric shock or product failure.

 Wait for at least six minutes after turning OFF the power supply (with a SERVOPACK for a 100-

VAC power supply input, wait for at least nine minutes) and then make sure that the CHARGE indicator is not lit before starting wiring or inspection work. Do not touch the power supply terminals while the CHARGE lamp is lit because high voltage may still remain in the SERVOPACK after turning OFF the power supply.

There is a risk of electric shock.

 Before you replace a SERVOPACK, back up the settings of the SERVOPACK parameters. Copy

the backed up parameter settings to the new SERVOPACK and confirm that they were copied correctly.

If you do not copy backed up parameter settings or if the copy operation is not completed normally, normal operation may not be possible, possibly resulting in machine or equipment damage.

xxii

 Discharge all static electricity from your body before you operate any of the buttons or switches

inside the front cover of the SERVOPACK.

There is a risk of equipment damage.

 Troubleshooting Precautions

DANGER

WARNING

CAUTION

 If the safety device (molded-case circuit breaker or fuse) installed in the power supply line oper-

ates, remove the cause before you supply power to the SERVOPACK again. If necessary, repair or replace the SERVOPACK, check the wiring, and remove the factor that caused the safety device to operate.

There is a risk of fire, electric shock, or injury.

 The product may suddenly start to operate when the power supply is recovered after a momen-

tary power interruption. Design the machine to ensure human safety when operation restarts.

There is a risk of injury.

 When an alarm occurs, remove the cause of the alarm and ensure safety. Then reset the alarm

or turn the power supply OFF and ON again to restart operation.

There is a risk of injury or machine damage.

 If the Servo ON signal is input to the SERVOPACK and an alarm is reset, the Servomotor may

suddenly restart operation. Confirm that the servo is OFF and ensure safety before you reset an alarm.

There is a risk of injury or machine damage.

 Always insert a magnetic contactor in the line between the main circuit power supply and the

main circuit power supply terminals on the SERVOPACK so that the power supply can be shut OFF at the main circuit power supply.

If a magnetic contactor is not connected when the SERVOPACK fails, a large current may flow, possibly resulting in fire.

 If an alarm occurs, shut OFF the main circuit power supply.

There is a risk of fire due to a regenerative resistor overheating as the result of regenerative transistor failure.

 Install a ground fault detector against overloads and short-circuiting or install a molded-case

circuit breaker combined with a ground fault detector.

There is a risk of SERVOPACK failure or fire if a ground fault occurs.

 The holding brake on a Servomotor will not ensure safety if there is the possibility that an exter-

nal force (including gravity) may move the current position and create a hazardous situation when power is interrupted or an error occurs. If an external force may cause movement, install an external braking mechanism that ensures safety.
