Servopack for Position Control
(1) Set parameter Cn-02 so that the reference pulse form matches the host controller out-
put form. Refer to 2.2.2 Position References for details on how to select reference
pulse forms.)

(2) Input slow speed pulses from the host control-
ler and execute low-speed operation.
(3) Check the following items in monitor mode:
Un-00 Actual motor speed
Un-07 Reference pulse speed display
Un-08 Position error
• Has a reference pulse been input?
• Is the motor speed as set?
• Does the reference speed match the actual Servomotor speed?
• Does the Servomotor stop when no reference is input?
(4) To change motor speed or the direction of rotation, reset the parameters shown be-
low.
Cn-24,Cn-25 Electronic gear ratio
Refer to 2.2.5 Electronic Gear.
Cn-02 bit 0 Reverse rotation mode
Refer to 2.1.1 Switching Motor Rotation Direction.
If an alarm occurs or the Servomotor fails to rotate during the above operation, connector
CN1 wiring is incorrect or the parameter settings do not match the host controller specifi-
cations. Check the wiring, review the parameter settings, and then repeat step 1.
