What are the faults of the five-phase hybrid stepping driver for embroidery machines?

Embroidery frame won't lock
1. Check whether the AC 100V stepping power supply is normal
2. 8P double row plug on the stepper driver 1.2-pin DC output 140V 3.7-pin AC 7V 4.8-pin AC 7V
A: The MON light is on normally
BE light on, low voltage regulated power supply
C: OC light is on 1. Over-current protection (10 seconds after shutdown) 2. Output power transistor is broken 3. Driver board is broken
Embroidery frame is lost, the movement of the embroidery frame is discontinuous and pauses
1. Check whether the X or Y stepping drive line of the stepping motor is open or not, etc.
2. Check the XY stepper driver (check the two drivers to see if the fault is resolved) or stepper motor
3. Observe whether the pattern can be returned to the origin after running
a Back to the origin may be a pattern problem b Can not return to the origin, it may be caused by interference of the stepper driver signal line or the stepper driver is damaged
3. Irregular running position, first X and then Y direction, the forward track of the embroidery frame is different from the backward direction, and the photoelectric encoder is damaged
D: OH light is on
1. The internal temperature of the drive is too high 2. The fan is broken. Clean or replace 3. The components on the board are damaged-replace the drive board 4. The transformer is damaged
EOWER light off
1. Damaged fuse 2. No input power 3. No voltage
3. Irregular running position, the forward track of the embroidery frame is different from the backward direction of X and Y direction, and the photoelectric encoder is damaged
