Common faults and troubleshooting methods
| Trouble | Cause | Solution |
| The voltage axis does not run after power-on | 1. The inverter has no output or the setting is incorrect | Check that the output setting of the AC is correct |
| 2.The plug is not inserted | check the plug and the connection | |
| 3. The plug connection is not good | ||
| 4. The spindle wire package is burned out | replace the wire package | |
| Run for a few seconds and then shut down after starting the machine | 1. Water damage to the insulation of the cable package | drying the cable package |
| 2. High temperature causes insulation damage to the wire package. | Replace the wire package | |
| 3. Overcurrent protection caused by phase loss operation | Check motor wiring | |
| 4. Start-up time is too short | Extended acceleration time | |
| After turning on for a few seconds, the motor emits smoke or the casing becomes hot. | 1. The inverter has no output voltage, overrate and the electric spindle brand voltage, and the frequency does not match. | Check the basic frequency setting of the inverter. |
| 2. Incorrect setting of the inverter | Reset the inverter | |
| 3. Waterway problems | Check if the waterway is unblocked | |
| The nut is loose when starting | Wrong rotation | Change direction by brand |
| High sound absorption and vibration | 1. The bearing wears out and produces weight. | Replace the bearing |
| 2. Damaged parts accuracy affects dynamic balance. | Check dynamic balance | |
| 3. The spindle has a big runout. | Replace the spindle | |
| Nuts loose during shutdown | Downtime is too short | Extend the deceleration time |
