CAUTION

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 option) between 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 of the servo amplifier must be wired in

the specified direction. Otherwise, the emergency stop (EMG) and other protective circuits may not

operate.
