GSK928TB User:

Hello, we are using a regular motor (Not AC servo or Frequency motor) on our lathe machine, and it is not connected to a frequency inverter, the CNC system is GSK928TB.

The problem is under Jog mode,  no matter pressing Rotate forward button, Rotate backward button, or execute M03, M04, they all became JOG. What goes wrong?
