1.Does the fault occur under light or heavy load?
- Occurs when opening the control box. The motor has not been driven yet.

2. what length have the wires been extended?
- 6 sq.mm for phase wire and 16 awg for hall wire.
Have you used the same gauge wires (or preferably a thicker gauge) to extend the Phase Wires and Hall/Temperature Sensor wires?
- Use a phase wire of size 6 sqmm. Connect it to the phase wire attached to the motor by fixing a nut through the wire terminal. by not solder it. As for the hall sensor wire, solder it on both sides between the control box and the motor.

4. Have you ensured that decent soldered or crimped joins were made in the wires?
Connect and solder according to the golden motor diagram. Because the box flashes 6 times, it only happens sometimes. Because it can still run the motor.

5. Are you sure that none of the wires have inadvertently been transposed during the modification?
- I'm sure none of the wires were moved.

It happened after I lengthened the hall sensor wire and U V W wire. Does it have any effect?

Hi KP, after reading this additional information, I now have a few questions for you:
  • Does the fault occur under light or heavy load?
  • By what length have the wires been extended?
  • Have you used the same gauge wires (or preferably a thicker gauge) to extend the Phase Wires and Hall/Temperature Sensor wires?
  • Have you ensured that decent soldered or crimped joins were made in the wires?
  • Are you sure that none of the wires have inadvertently been transposed during the modification?

These vector controllers are designed specifically to work with certain motors, therefore lengthening the motor's Phase Wires may well have changed the overall resistance and/or inductance of the motor's stator windings, causing an incompatibility problem between controller and motor, especially if thinner wires have been used or poor connections were made.

It would probably have been much better to mount the controllers closer to the motors and then extend the Battery cables and control harness wiring, as this would not have affected the overall resistance or inductance of the stator windings.

There are 2 sets of vector 200 controller and bldc motor 3kw. Both sets have 6 flashing warning lights: mosfet protection is the same, but both boxes will switch to Not at the same time
You have to turn the box on and off again and then it can be used again.

Hi Leon,

Thanks for the update, it's good to know that the 24V setting has cured the problem.

Hello, I'm a student. I'm having a problem with the vector 200 control box. The status indicator blinks 6 times: Mosfet protection; Mosfet is abnormal. Can you help me? What is the cause and how can it be fixed?

thank you

Hi Alan,

I tried and it worked, it makes a big difference in accelerating. Thank you for your advice, problem solved!!

Kind Regards leon :)

Hi Alan,

Thank you for reply. I will try 24v setting.

But it seems that the acceleration curve is so defined that from standing still and accelerating it takes a while before 15Amps is consumed by motor ( the current is slowly building up). I would expect when starting with full trottle moter would consume 15 amps immediate and taking down the current when reaching max speed.

Kind regards leon
