Troubleshooting before operation
Fault phenomenon | Fault reason | Handling methods |
|
| Check the input power specifications of the driver and measure whether the input voltage on the non driver side and driver side (L1 L2 L3) of the main circuit cable meets the following specifications: 220V driver Effective value: 220V-240V Allowable deviation: -10%~+10% (198V~264V) 380V driver Effective value: 380V-440V Allowable deviation: -10%~+10% (342V~484V) |
2、servo driver fault | Back to factory repair. | |
After the servo enable signal is set to ON, the servo motor is in a free running state | 1.The servo enable signal is invalid (the two digital tubes at the last of the tube display "rd" instead of "ru") | 1. Check P01 group to see if the servo enable signal DI terminal and effective logic are correctly set. The factory default DI1 configuration is servo enable signal input ("P1-04 DI1 terminal function selection" is set to "[1] servo enable"), and "P1-20 DI1 terminal logic selection" is set to "[0] ON effective") 2. Check if the external enable switch circuit is working properly |
2. Control mode selection error | Check if the 'P0-00 Control Mode Selection' is incorrectly configured as' [2] Torque Mode '(default torque command is zero) | |
3. Wiring error | 1. Check if the power lines U, V, W, and PE of the motor are reliably connected to the servo | |
4. Motor damage | 2. Check if the power lines of other axis motors have been connected to the driver incorrectly | |
Panel display “AL.xxx” | Servo malfunction | Replace the motor |
