we worked in an AGV using a kelly controller KLS-4812S with QS-BLDC hub motor, the all wiring at the photo attached we connected them correctly and an 1-3 error for (LOW VOLTAGE) still appear and we checked the whole circuit to catch any fault but with no way.. anyone can help us with that.
also we tried a spare new motor and new controller with the same wiring when switch the power on, there's an initial torque that wraps motor for only half rev. which takes milliseconds and when change the value of Throttle, no change occurs although the green led is on and the red led detected the LOW VOLTAGE error for about one or two times and the green led retured on.
also we simulated with the kelly software and if anyone have some hints about the changing parameters, i'll be pleased with that
all the components shown is wiring including the resistor (1kohm but with no contactor), foot sw, brake sw, fuses and diodes except the hall sensor connection with motor
finally how we can check if the controller is fully damaged or not? or its only the leds break down?
