I found my microtouch motor got warm after several minutes. I turned off the duty cycle from the robofocus controller but no help. After debugging, I found I accidentally put the useless (I guess 12v) yellow wire into the motor. After removing it, the motor still works and no more warm.

With the new purchased focus motor, finally address the problem of focus position slipping.
I re-use robofocus controller on the new motor and here is how to wire it correctly.
Works great. Happy.
