1. Check if the 3-wire connector from the inverter to the spindle is disconnected. Solution: Reinsert or reconnect, and then try again.

2. Check whether the leads inside the engraving machine spindle motor are desoldering. Determine the method: Use a multimeter to measure the resistance between the three cores of its socket. Solution: Remove the socket and re-solder it.

3. Check whether the three-wire cable from the spindle motor to the inverter is broken. Confirmation method: Use a multimeter to measure the resistance between the plugs at both ends of the cable. Solution: Connect the broken wire or replace the line.

4. It may also be that some other brands use a lot of lower-configuration machine tool spindles, which may be good at the beginning, but after a certain period of use, faults will appear one after another. It is recommended that customers look for regular equipment source manufacturers and purchase high-quality machine tools as much as possible.
