Never adjust or change the parameter values extremely as it will make operation unstable.
Do not get close to moving parts during the servo-on status.
(4) Usage
When it is assumed that a hazardous condition may occur due to a power failure or product malfunction,
use a servo motor with an external brake to prevent the condition.
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. Otherwise, an electric shock, fire, injury, etc. may
occur. 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.
Use a noise filter, etc. to minimize the influence of electromagnetic interference. Electromagnetic
interference may be given to the electronic equipment used near the servo amplifier.
Burning or breaking a servo amplifier may cause a toxic gas. 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, an electric
shock, fire, injury, etc. may occur.
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
Ensure safety by confirming the power off, etc. before performing corrective actions. Otherwise, it may
cause an accident.
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.
When any alarm has occurred, eliminate its cause, ensure safety, and deactivate the alarm before
restarting operation.
If the molded-case circuit breaker or fuse is activated, be sure to remove the cause and secure safety
before switching the power on. If necessary, replace the servo amplifier and recheck the wiring.
Otherwise, it may cause smoke, fire, or an electric shock.
Provide an adequate protection to prevent unexpected restart after an instantaneous power failure.
