Mitsubishi Electric MELSERVO-J4 Series Instruction Manual page 8

[Usage]
CAUTION
● Provide an external emergency stop circuit to stop the operation and shut the power 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. Otherwise, it may cause an electric shock, fire,
injury, etc. 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 affect the electronic equipment used near the servo amplifier.
● Do not burn or destroy the servo amplifier. Doing so may generate a toxic gas.
● Use the servo amplifier with the specified servo motor.
● Wire options and peripheral equipment, etc. correctly in the specified combination. Otherwise, it may
cause an electric shock, fire, injury, etc.
● 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.
