GS3048Y AC Servo Spindle Driver User:

Dear CNCmakers, there is err-2 alarm on the GS3048Y AC servo spindle driver, what should we do?

CNCmakers Support:

Err-2 means the input voltage is overload, please kindly check is the braking resistor connected or not? If it is connected, then is it broken?

Or the unstable input voltage could also cause the err-2 alarm.
