(2) Wiring
CAUTION
Wire the equipment correctly and securely. Otherwise, the servo motor may operate unexpectedly.
Do not install a power capacitor, surge killer, or radio noise filter (FR-BIF option) on the servo amplifier
output side.
To avoid a malfunction, connect the wires to the correct phase terminals (U, V, and W) of the servo
amplifier and servo motor.
Connect the servo amplifier power output (U, V, and W) to the servo motor power input (U, V, and W)
directly. Do not let a magnetic contactor, etc. intervene. Otherwise, it may cause a malfunction.

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 make a drastic adjustment or change to the parameter values as doing so will make the operation
unstable.
(4) Usage
CAUTION
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.
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 equipment.
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 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.
