(2) Wiring
CAUTION
Wire the equipment correctly and securely. Other wise, the servo motor may operate unexpectedly.
Do not install a power capacitor, surge absorber or radio noise filter (FR-BIF-(H) option) between the
servo motor and servo amplifier.
Connect the wires to the correct phase terminals (U, V, W) of the servo amplifier and servo m otor.
Not doing so may cause unexpected operation.
Connect the servo motor power terminal (U, V, W ) to the servo motor power input terminal (U, V , W)
directly. Do not let a magnetic contactor, etc . intervene.

Do not connect AC power directly to the servo m otor. Otherwise, a fault may occur.
The surge absorbing diode installed on the DC o utput signal relay of the servo amplifier must be wired in
the specified direction. Otherwise, the forced stop (EMG) and other protective circuits ma y not operate.

When the cable is not tightened enough to the ter minal block (connector), the cable or terminal block
(connector) may generate heat because of the po or contact. Be sure to tighten the cable with sp ecified
torque.

CAUTION
Before operation, check the parameter settings. Improper settings may cause some machines to perform
unexpected operation.
The parameter settings must not be changed exc essively. Operation will be insatiable.
