CAUTION
Provide adequate protection to prevent screws and other conductive matter, oil and other combustible
matter from entering the converter unit, servo amplifier (drive unit), and servo motor.
Do not drop or strike converter unit, servo amplifier (drive unit), or servo motor. Isolate from all impact
loads.
Securely attach the servo motor to the machine. If attach insecurely, the servo motor may come off during
operation.
The servo motor with reduction gear must be installed in the specified direction to prevent oil leakage.
Take safety measures, e.g. provide covers, to prevent accidental access to the rotating parts of the servo
motor during operation.
Never hit the servo motor or shaft, especially when coupling the servo motor to the machine. The encoder
may become faulty.
Do not subject the servo motor shaft to more than the permissible load. Otherwise, the shaft may break.
When the equipment has been stored for an extended period of time, consult Mitsubishi.
(2) Wiring
CAUTION
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 (-H) option) between the
servo motor and servo amplifier (drive unit).
Connect the output terminals (U, V, W) correctly. Otherwise, the servo motor will operate improperly.
Connect the servo motor power terminal (U, V, W) to the servo motor power input terminal (U, V, W)
directly. Do not let a magnetic contactor, etc. intervene.

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 of the servo amplifier (drive unit) must
be wired in the specified direction. Otherwise, the forced stop (EM1) and other protective circuits may not
operate.

When the cable is not tightened enough to the terminal block (connector), the cable or terminal block
(connector) may generate heat because of the poor contact. Be sure to tighten the cable with specified
torque.
