A - 5
CAUTION
Do not connect AC power supply directly to the servo motor. Otherwise, it may cause a malfunction.
When the cable is not tightened enough to the terminal block, the cable or terminal block may generate
heat because of the poor contact. Be sure to tighten the cable with specified torque.
(3) Test run and adjustment
CAUTION
Before operation, check the parameter settings. Improper settings may cause some machines to operate
unexpectedly.
Never adjust or change the parameter values extremely as it will make operation unstable.
(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 scratch the coated surface with hard objects nor clean the coated surface with an organic solvent.
Doing so may scuff the surface.
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.
Use the servo amplifier (converter unit) 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.
