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.
For safety of personnel, always cover rotating and moving parts.
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
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 must be wired in the specified
direction. 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 machines to
perform unexpected operation.
The parameter settings must not be changed excessively. Operation will be instable.
