(2) Wiring
CAUTION
Wire the equipment correctly and securely. Otherwise, the servo motor may operate unexpectedly.
Do not install a power capacitor, surge killer, or radio noise filter (optional FR-BIF) on the output side of
the servo amplifier.
Because installation of these items may cause the servo motor to malfunction, connect the wires to the
correct phase terminals (U/V/W) of the servo amplifier and servo motor power supply.
Directly connect the servo amplifier power output (U/V/W) to the servo motor power input (U/V/W). Do not
let a magnetic contactor, etc. intervene. Otherwise, it may cause a malfunction.
The connection diagrams in this Instruction Manual are shown for sink interfaces, unless stated otherwise.
The surge absorbing diode installed to the DC relay for control output should be fitted in the specified
direction. Otherwise, the emergency stop and other protective circuits may not operate.
When the cable is not tightened enough to the terminal block, the cable or terminal block may generate
heat because of the poor contact. Be sure to tighten the cable with specified torque.
To avoid a malfunction, do not connect the U, V, W, and CN2 phase terminals of the servo amplifier to the
servo motor of an incorrect axis.
Configure a circuit to turn off EM2 or EM1 when the main circuit power is turned off to prevent an
unexpected restart of the servo amplifier.
(3) Trial run/adjustment
CAUTION
Before operation, check the parameter settings. Improper settings may cause some machines to operate
unexpectedly.
Never perform extreme adjustment or changes to the parameters; otherwise, the operation may become
unstable.
Keep away from moving parts in a servo-on state.
