Tips: 1.5kW CNC Spindle Motor Using Case
A customer inquired that his engraving machine has been purchased for 10 years, and it has been used normally. However, during recent use, the 1.5kW spindle motor of the engraving machine stopped suddenly and the VFD displayed ERR 01. Sometimes the motor is energized with a buzzing sound, but it does not rotate. After the situation occurred, the client did not understand the reason, so consulted ATO. Below is a summary of the reasons and solutions for the spindle of the CNC engraving machine to stop, for the reference of the majority of users:
1. The three-wire cable plug-in connecting the spindle motor to the inverter is disconnected. Solution: Reconnect or reconnect and try again.
2. The lead wire in the spindle motor of the engraving machine is open welding. Confirmation method: Measure the resistance between the three cores of the spindle motor socket with a multimeter. Solution: Remove the socket and re-solder the open wire.
3. The three-wire cable connecting the spindle motor to the frequency inverter is disconnected. Confirmation method: Measure the resistance between the plugs at both ends of the cable with a multimeter. Solution: Connect the broken wire or replace the wire.
