The servo drive display 0 is normal, the simplest detection method, rotate the motor rotor wheel by hand, the number on the server keeps changing without showing the fault code, stop the rotation display returns to zero, indicating that there is no fault. Most of the servo drives display zero when they are normal, such as Dongyuan, Mountain, Dongling and other servo drives. The fault code of Dongyuan server displays AL 1 XX, the fault code of Mountain server displays E I F 1 XX, and the fault code of Dongling server displays Err 1 XX. As long as the fault code is detected by the above method, the 0 displayed on the power-on is normal
The servo drive has no alarm No. 0, indicating that no alarm has occurred at present, the servo drive is waiting to start, and the motor is not running. When the server starts the motor to run, the encoder will feedback signals to the server computer control board, after CPU processing, the digital tube will display constantly changing numbers, this number is the current motor synchronous belt value.
Servo driver No. 0 alarm solution
If this alarm appears immediately, use a new drive. 2) Check the motor cable to ensure that UkV and W are not short-circuited. Connect motor cables correctly. 3) Check the insulation resistance of U, V, W and ground wire respectively. If the insulation is damaged, replace it with a new machine. 4) Check the resistance value between U, V and W of the motor cable. If the resistance value is not balanced, use a new drive. 5) Check whether the UUV and W terminals of the motor are loose or not connected.
