CAUTION
Securely attach the servo motor to the machine. If at tach insecurely, the servo motor may come off during
operation.
The servo motor with reduction gear must be ins talled in the specified direction to prevent oi l leakage.
Take safety measures, e.g. provide covers, to pr event accidental access to the rotating par ts of the servo
motor during operation.
Never hit the servo motor or shaft, especially when cou pling 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 br eak.
When the equipment has been stored for an exten ded period of time, consult Mitsubishi.
(2) Wiring
CAUTION
Wire the equipment correctly and securely. Ot herwise, the servo motor may misoperate.
Do not install a power capacitor, surge absorber or radio noise filter (FR-BIF option) between the servo
motor and servo amplifier.
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 m otor. Otherwise, a fault may occur.
The surge absorbing diode installed on the DC output signal relay of the servo amplifier must be wired in
the specified direction. Otherwise, the forc ed stop (EM1) and other protective circuits m ay not operate.

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