1. Secure the servomotor.
Secure the servomotor mounting plate to the equipment in order to prevent the
servomotor from moving during operation.
2. Check the wiring.
Disconnect the CN1 connector and check servomotor wiring in the power supply
circuit. The CN1 I/O signals are not used, so leave the connector disconnected.
3. Turn ON power.
Turn ON servo amplifier power. If the servo amplifier has turned ON normally,
the LED display on the front panel of the servo amplifier will appear as shown
above. Power is not supplied to the servomotor because the servo is OFF.
If an alarm display appears on the LED indicator as shown above, the power
supply circuit, servomotor wiring, or encoder wiring is incorrect. In this case,
turn OFF power and take appropriate action. See
9.2 Troubleshooting.
Note If an absolute encoder is used, it must be set up. Refer to 5.7.4 Absolute Encoder Setup.
Secure the mounting plate of the
servomotor to the equipment.
Do not connect anything to the sha
(no-load conditions).
Disconnect the CN1
connector.
