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.
Take safety measures, e.g. provide co vers, to prevent accidental access to th e rotating parts of the servo
motor during operation.
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 mot or w ill op erat e i mprop e rly .

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 signal relay of the s ervo amplifier must be wired in
the specified direction. Otherwise , the emergency stop (EMG) and other protective circuits may not
operate.
