A - 5
(3) Trial run/adjustment
CAUTION
When executing a test run, follow the notice and procedures in this instruction manual. Otherwise, it may
cause a malfunction, damage to the machine, or personal injury.
Before operation, check the parameter settings. Improper settings may cause some machines to operate
unexpectedly.
Never perform extreme adjustment or changes to the parameters; otherwise, the operation may become
unstable.
Keep away from moving parts in a servo-on state.
(4) Usage
CAUTION
Provide an external emergency stop circuit to ensure that operation can be stopped and power switched
off immediately.
For equipment in which the moving part of the machine may collide against the load side, install a limit
switch or stopper to the end of the moving part. The machine may be damaged due to a collision.
Do not disassemble, repair, or modify the product.
Disassembled, repaired, and/or modified products are not covered under warranty.
Before resetting an alarm, make sure that the run signal of the servo amplifier is off in order to prevent a
sudden restart. Otherwise, it may cause an accident.
The effect of electromagnetic interference must be reduced by using a noise filter or by other means.
Electromagnetic interference may be given to the electronic equipment used near the servo amplifier.
Burning or disassembling a servo amplifier may generate toxic gases. Do not burn or break it.
Use the servo amplifier with the specified servo motor.
Correctly wire options and peripheral equipment, etc. in the correct combination. Otherwise, it may cause
an electric shock, fire, or injury.
The electromagnetic brake on the servo motor is designed to hold the motor shaft and should not be used
for ordinary braking.
For such reasons as incorrect wiring, service life, and mechanical structure (e.g. where a ball screw and
the servo motor are coupled via a timing belt), the electromagnetic brake may not hold the motor shaft. To
ensure safety, install a stopper on the machine side.
If the dynamic brake is activated at power-off, alarm occurrence, etc., do not rotate the servo motor by an
external force. Otherwise, it may cause a fire.
(5) Corrective actions
CAUTION
If it is assumed that a power failure, machine stoppage, or product malfunction may result in a hazardous
situation, use a servo motor with an electromagnetic brake or provide an external brake system for
holding purpose to prevent such hazard.
