(2) Wiring
CAUTION
Before unplugging CNP1 connector from the driver, disconnect the lead of the built-in regenerative resistor
from CNP1 connector first.
Wire the equipment correctly and securely. Improper wiring may cause unexpected operation.
Do not install a power capacitor, a surge absorber or a radio noise filter (FR-BIF: Mitsubishi Electric
Corporation) between the servo motor and the driver.
Connect the wires to the correct phase terminals (U, V, W) of the driver and the servo motor. Not doing so
may cause unexpected operation.
Connect the servo motor power terminals (U, V, W) of the driver to the servo motor power input terminals
(U, V, W) directly. Do not install a magnetic contactor, etc. between the driver and the servo motor.

Do not connect AC power supply directly to the servo motor. Otherwise, a fault may occur.
Install a surge absorbing diode on the DC relay designed for control output signal in the specified direction.
Improper installation of the surge absorbing diode may cause the driver to malfunction such that the
signals are not output, and emergency stop and other safety circuits are inoperable.

CAUTION
Check and adjust the parameter setting before operation. Improper settings may cause some machines to
perform unexpected operation.
Never adjust or change the parameter values extremely as it makes operation instable.
