CAUTION

• Always use the servomotor and SERVOPACK in one of the specified combinations.

Failure to observe this caution may result in fire or malfunction.

• Conduct trial operation on the servomotor alone with the motor shaft disconnected from the

machine to avoid accidents.
Failure to observe this caution may result in injury.

• During trial operation, confirm that the holding brake works correctly. Furthermore, secure system

safety against problems such as signal line disconnection.

• Before starting operation with a machine connected, change the parameter settings to match the

parameters of the machine.
Starting operation without matching the proper settings may cause the machine to run out of control or mal-

function.

• Do not turn the power ON and OFF more than necessary.

Do not use the SERVOPACK for applications that require the power to turn ON and OFF frequently. Such

applications will cause elements in the SERVOPACK to deteriorate.
As a guideline, at least one hour should be allowed between the power being turned ON and OFF once actual
operation has been started.

• When carrying out JOG operation (Fn002), origin search (Fn003), or EasyFFT (Fn206), forcing

movable machine parts to stop does not work for forward overtravel or reverse overtravel. Take

necessary precautions.
Failure to observe this caution may result in damage to the equipment.

• When using the servomotor for a vertical axis, install safety devices to prevent workpieces from fall-

ing due to alarms or overtravels. Set the servomotor so that it will stop in the zero clamp state when

overtravel occurs.
Failure to observe this caution may cause workpieces to fall due to overtravel.

• When not using the turning-less function, set the correct moment of inertia ratio (Pn103).

Setting an incorrect moment of inertia ratio may cause machine vibration.

• Do not touch the SERVOPACK heat sinks, regenerative resistor, or servomotor while power is ON

or soon after the power is turned OFF.
Failure to observe this caution may result in burns due to high temperatures.

• Do not make any extreme adjustments or setting changes of parameters.

Failure to observe this caution may result in injury or damage to the equipment due to unstable operation.

• When an alarm occurs, remove the cause, reset the alarm after confirming safety, and then resume

operation.
Failure to observe this caution may result in damage to the equipment, fire, or injury.

• Do not use the holding brake of the servomotor for braking.

Failure to observe this caution may result in malfunction.

• 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 stop the current process and stop the system.

CAUTION

• Do not disassemble the SERVOPACK and the servomotor.

Failure to observe this caution may result in electric shock or injury.

• Do not attempt to change wiring while the power is ON.

Failure to observe this caution may result in electric shock or injury.

• When replacing the SERVOPACK, resume operation only after copying the previous SERVOPACK

parameters to the new SERVOPACK.
Failure to observe this caution may result in damage to the equipment.

CAUTION

• When disposing of the products, treat them as ordinary industrial waste.
