Rockwell Automation SA3100 Power Module Interface (PMI) Regulator - Manual (Page 65)

Diagnostics and Troubleshooting 6-3
6.1.7 Overtemperature Fault (Bit 7)
LED indicator: P.M. FLT
The Overtemperature Fault bit is set if the internal temperature of the Power Module’s
heatsink exceeds 100° C. Error code 1016 will be displayed in the error log of the
UDC task in which the fault occurred.
6.1.8 Resolver Broken Wire Fault (Bit 8)
LED indicator: FDBK OK
The FDBK OK LED is turned off, and the Resolver Broken Wire Fault bit is set if a sine
or cosine signal from the resolver is missing due to a broken wire or the resolver gain
tunable (RES_GAN%) has been set too low.
6.1.9 Resolver Fault (Bit 9)
LED indicator: N/A
The Resolver Fault bit is set if a blown fuse is detected on the Resolver & Drive I/O
board. This indicates the Resolver & Drive I/O board must be replaced.
6.1.10 Overspeed Fault (Bit 9)
LED indicator: EXT FLT
The Overspeed Fault bit is set if the motor’s velocity exceeds the value entered as the
Overspeed Trip (RPM) configuration parameter.
6.1.11 AC Power Technology Fault (Bit 11)
LED indicator: DRV RDY
The DRV RDY LED is turned off, and the AC Power Technology Fault bit is set to
indicate that an error occurred in the PMI Regulator’s AC power technology circuitry.
Power should be recycled to allow the Regulator to clear itself and reboot. If the DRV
RDY LED remains off after repeated cycling of power, check the Diagnostic Fault
Code register (222/1222) for specific information.
6.1.12 PMI Regulator Bus Fault (Bit 13)
LED indicator: N/A
This fault indicates that the Resolver & Drive I/O board and the AC power technology
circuitry do not respond to requests from the PMI processor. This indicates a
hardware failure in the PMI Regulator.
6.1.13 UDC Run Fault (Bit 14)
The UD Run Fault bit is set if the UDC task stops while the minor loop is running in the
PMI Regulator.
