I agree with Solidstate, they have been great to deal with. EMI/Porta sells components to many manufacturers. I’ve seen these drives and boards used in Savaria packages.
Do you have a ptool?
Is the control board registering an up and down commands?
The wires you swapped, were they the wires from the drive to the motor?
If this is a Savaria package elevator I suggest you call 800 265-5416 ask for Kerri or Jeremie. They are awesome to work with!
