    Hi guys new member here
    I have been working with the SMC3 and the IBT-2 controllers with 24v wheelchair motors
    I have been able to get my RH motor functioning properly
    On the left motor I can start the program for motion but as soon as I add some pvMmax to get the motor to start to rotate it takes off and over rotates and shuts down. I have checked and all wiring is correct. The potentiometer is working and all settings are the same as the functioning RH motor.
    Any ideas?

    Are you sure the pot is properly centred?

    If you swap the IBT2 to the other motor does the problem follow?

    Yes I have checked the center on the pot. I will swap the IBT2 in the morning and see what happens.

    I swapped the IBT2 and yes the problem is in the controller. I have a new controller on the way and bought a spare while I was at it.
    Thanks for the quick response
