Problem with the VEC200 controller

(1/2) > >>

KP:
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

KP

Hi KP andto the forum.

Please check out this post for further information regarding your 6 blink error code.

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

KP:
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 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.
