(2) Wiring
Wire the equipment correctly and securely. Otherwise, the servo motor may misoperate
Do not install a power capacitor, surge absorber or radio noise filter (FR-BIF option) be-
tween the servo motor and servo amplifier.
Connect the output terminals (U, V, W) correctly. Otherwise, the servo motor will operate improperly.
Do not connect AC power directly to the servo motor. Otherwise, a fault may occur.
The surge absorbing diode installed on the DC output signal relay must be wired in the specified direc-
tion. Otherwise, the emergency stop and other protective circuits may not operate.
(3) Test run adjustment
Before operation, check the parameter settings. Improper settings may cause some ma-
chines to perform unexpected operation.
The parameter settings must not be changed excessively. Operation will be instable.
(4) Usage
Provide an external emergency stop circuit to ensure that operation can be stopped and
power switched off immediately.
Any person who is involved in disassembly and repair should be fully competent to do the
work.
Before resetting an alarm, make sure that the run signal is off to prevent an accident. A
sudden restart is made if an alarm is reset with the run signal on.
Do not modify the equipment.
Use a noise filter, etc. to minimize the influence of electromagnetic interference, which
may be caused by electronic equipment used near the servo amplifier.
Use the servo amplifier with the specified servo motor.
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 service life and mechanical structure (e.g. where a ballscrew 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
