Z axis motor always faulting

Sometimes when reseting the Z axis on my Tormach 1100m the motor will fault . I emd up going through the reset again and again until it resets correctly. Does anyone know why this is happening? Thank you.

I see you already have a case open with Craig. Just to clarify, do you have an 1100M or 1100MX? Looks like you listed M here, but MX in your case.
