3. Check whether the driver board card is burned; (this can be judged according to the light on the drive in the box, usually the green light is normal. The red light is abnormal) four, the main shaft motor to the frequency converter three-wire cable broken line. Verification method: the resistance between the ends of the multimeter cable.
Solution: pick up or replace the broken line;
Fifth, spindle motor to frequency converter three-wire cable connector release.
Solution: reconnect or reconnect to try again;
Vi. The main shaft motor of the engraving machine is welded with the lead wire. Confirmation method: multimeter main shaft motor socket three core resistance.
