(2) Wiring
Wire the equipment correctly and securely. Otherwise, the servo motor may operate unexpectedly.
Make sure to connect the cables and connectors by using the fixing screws and the locking mechanism.
Otherwise, the cables and connectors may be disconnected during operation.
Do not install a power capacitor, surge killer, or radio noise filter (optional FR-BIF) on the servo amplifier
output side.
To avoid a malfunction, connect the wires to the correct phase terminals (U/V/W) of the servo amplifier
and servo motor.
Connect the servo amplifier power output (U/V/W) to the servo motor power input (U/V/W) directly. Do
not let a magnetic contactor, etc. intervene. Otherwise, it may cause a malfunction.
Servo amplifier
Do not connect AC power supply directly to the servo motor. Otherwise, it may cause a malfunction.
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.
(3) Test run and adjustment
Before operation, check the parameter settings. Improper settings may cause some machines to operate
unexpectedly.
Never make a drastic adjustment or change to the parameter values as doing so will make the operation
unstable.
