Encoder Error 2 Initial Calibration Sequence

I get and encoder error 2 with the initial calibration sequence; tried all the suggest possible corrections.
PPR is correct; Pole Pairs is correct and tried various values for calib_scan_distance still get error 2.

Any thoughts; Oh yeah 56v 3.6 controller, D5065 motor and AMT102 configured dip switches all 0 so 2048 PPR.

Figured it out; bad AMT102.
