Appendix 6. General debugging steps 
1. Motor empty shaft, preliminary debugging 
A. Connect the cable correctly. Pay attention to the one-to-one connection of U, V, W and PE terminals, 
and the phase sequence can not be crossed. 
B. Open-loop test run: The test run mainly checks the power cable and the encoder feedback cable to 
determine  whether  the  connection  is  normal.  According  to  the  following  operation,  the  motor  can 
normally achieve  positive and  negative rotation.  If  the motor shaft shakes  or prompts the  alarm,  it 
needs to cut off the power supply immediately, and re-check the wiring situation.

Short press ENTER to enable the motor. In the enabled status, press INC for run forward, press DEC to 
run reverse. Press STATUS/ESC to exit.

2. Debug the motor with the machine 
A. Observe the operating direction of the machine head. If it is contrary to the actual need, after 
the servo OFF, set the parameter P0-05 to 1, and then re-energize to make the change effective. 
B. During the operation, observe the stability and responsiveness of the operation, and adjust the 
servo control parameters appropriately.
