D-2 Diagnositics, Troubleshooting, and Start-Up Guidelines
AC Power Technology Calibration and Power-Up Faults:
The following calibration and power-up diagnostic faults indicate an irreparable hardware failure of the AC
power technology circuitry on the PMI Regulator motherboard. If any of these faults occurs, replace the PMI
Regulator motherboard.
Register 202, bit 11 (FLT_PTM@) will be set.
Code Fault Action
1 D/A high voltage error (+3.3V 10% out of tolerance)
Replace PMI Regulator
Motherboard
2 D/A low voltage error (-3.3V 10% out of tolerance)
3 Torque current loop proportional gain not within calibration limits
(14<g<30)
4 Flux current loop proportional gain not within calibration limits
(14<g<30)
5 Flux current loop integrator time constant not within calibrated
limits
6 Torque current loop integrator time constant not within
calibrated limits
7 Modulation index error
8 Harmonic DAC limit error
9 Modulation range error
10 Harmonic DAC range error
11 Programmable current limit or the ground fault limit fault
12 Voltage feedback integrator error
