AC Servo No Action When Threading


GSK980TA CNC Lathe Controller User:

Our CNC lathe with GSK980TA CNC system can turn round bar, but it could not make thread, the spindle speed on CNC screen seems normal when running the thread program, but when the program runs to thread block, then the AC servo motor and driver will stop and there is no any alarm code, we tried to change the spindle encoder but it doesn't helped, the wiring of spindle encoder is fine too, what else should we check? Thank you.


CNCmakers Support:

The A or B signal from the spindle encoder is not delivered to the CNC, or the interface port of GSK980TA has problem.
