4. Reset the following parameters to change the motor speed or direction of
rotation.
Operating Procedure In Position Control Mode: Set Pn000.1 to 1
1. Set the parameter Pn200.0 so the reference pulse form is the same as the host
controller output form.
Selecting the reference pulse form: See 5.2.2 Position Reference.
2. Input a slow speed pulse from the host controller and execute low-speed
operation.
3. Check the following data in Monitor Mode. See 7.1.7 Operation in Monitor
Mode.
• Has the reference pulse been input?
• Is the motor speed as designed?
• Does the reference speed coincide with the actual motor speed?
• Does the servomotor stop when the speed reference is 0?
4. Reset the parameters shown below to change the motor speed or direction of
rotation.
If an alarm occurs or the servomotor fails to operate during the above operation,
CN1 connector wiring is incorrect or parameter settings do not match the host
controller specifications. Check the wiring and review the parameter settings,
then repeat step 1.
Note: References
• List of alarms: See 9.2.3 Alarm Display Table.
• List of parameters: See Appendix B List of Parameters.
