Spindle or Inverter Abnormal Alarm

GSK980TDc User:
We have a lathe machine equipped with GSK980TDc lathe CNC controller, the CNC alarms every time as soon as it connects to PC, the alarm is: Spindle or Inverter Abnormal Alarm
And the alarm will be removed after disconnect the cable between CNC and PC, what's the problem?
CNCmakers Support:
If there is no alarm on AC servo spindle driver or the inverter, then the problem should come from the cable, please change another cable and try again.
