Mitsubishi Electric Melservo-J2-SUPER series Instruction Manual page 5

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 forced stop (EMG) 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 insatiable.
