18 - Field Driver Fault R
Fault Signal from H-Bridge board
H bridge board detected abnormal over current

19 - Field Over current R
more than 45 Amps
Right motor field over-current is 45 A or more

So which motor did you build this caliper on? Was it the right motor by chance?
maybe the caliper is hanging up and holding the motor?
Just a guess since this problem came up immediately after you built a caliper?

Check the field wires (red black?) from right drive motor back to the control boards -may be bad h-board or main board if harness is ok
