7. Turn ON the servo.
Turn ON the servo using the following procedure.
a) Make sure there are no reference signals input.
• Set V-REF (CN1-5) and T-REF (CN1-9) to 0 V for speed and torque control.
• Set PULS (CN1-7) and SIGN (CN1-11) to low for position control.
b) Turn ON the servo ON signal.
Set /S-ON (CN1-40) to 0 V. If normal, the servomotor will turn ON and the LED
indicator on the front panel will display as shown above. If an alarm display appears,
take appropriate action as described in 8.2 Troubleshooting.
If there is noise in the reference voltage for speed control, the “-” on the left of the 7-segment LED
may flash.
