I have a miprom 21 with drive conversion done so using the magnetek 412 drive. I am getting a 45 fault on computer. changed out both motor and car encoders still have issue checked parameter 10 on drive its set right. checked all connections for loose or broken wires found nothing check shielded wires from drive to encoder no issues. If I change Bt and B- i get control of car but run revered direction. and help would be great thank you.
