„ Operation (cont’d)
CAUTION
• When using JOG operations (Fn002) origin search operations (Fn003), or
EasyFFT operations (Fn206), the dynamic brake function does not work for
reverse overtravel or forward overtravel. Take necessary precautions.
Failure to observe this caution may result in damage to the product.
• When using the servomotor for a vertical axis, install safety devices to pre-
vent workpieces from falling due to alarms or overtravels. Set the servomo-
tor 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 turning-less function, set to the correct moment of inertia
ratio (Pn103).
Setting to an incorrect moment of inertia ratio may cause vibration.
• Do not touch the SERVOPACK heatsinks, regenerative resistor, or servo-
motor 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 product 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 product, fire, or injury.
• Do not use the holding brake of the servomotor for braking.
Failure to observe this caution may result in malfunction.
• Always use the servomotor and SERVOPACK in one of the specified com-
binations.
Failure to observe this caution may result in fire or malfunction.
• The servomotor stopping method of turning the main-circuit or control-cir-
cuit power OFF without turning the servo OFF during operation can not be
set in Parameter Pn001. Use the following method to stop the servomotor.
• When turning the main-circuit power OFF without turning the servo OFF:
The servomotor will be stopped by dynamic braking (DB).
• When turning the control-circuit power OFF without turning the servo OFF:
The stopping method will vary depending on the SERVOPACK model.
