CAUTION
Securely attach the servo motor to the m achine. If attach insecurely, the serv o motor may come off during
operation.
The servo motor with reduction gear m ust be installed in the specified dir ection to prevent oil leakage.
For safety of personnel, always cover rotating and moving parts.
Never hit the servo motor or shaft, espec ially when coupling the servo motor t o the machine. The encoder
may become faulty.
Do not subject the servo motor shaft to m ore than the permissible load. Other wise, the shaft may break.
When the equipment has been stored for an extended period of time, consult M itsubishi.
(2) Wiring
CAUTION
Wire the equipment correctly and secur ely. Otherwise, the servo motor m ay misoperate.
Do not install a power capacitor, surg e absorber or radio noise filter (F R-BIF option) between the servo
motor and servo amplifier.
Connect the output terminals (U, V, W ) correctly. Otherwise, the servo m otor will operate improperly.
Do not connect AC power directly to the s ervo motor. Otherwise, a fault may occ ur.
The surge absorbing diode installed on the DC output si gna l rel ay must be wi red in th e spe ci fie d di re ctio n .
Otherwise, the emergency stop and other protective circuits may not operate .
