Rockwell Automation SA500 Drive Configuration and Programming - Manual (Page 65)

Configuring the UDC Module’s Registers 3-33
Drive Fault Register (Continued) 202/1202
Overspeed / Slip > 100% Bit 10
The Overspeed / Slip > 100% bit is set if the
motor’s velocity exceeds the value entered
as the Overspeed Trip (RPM) configuration
parameter. Hex Value: 0400H

UDC Error Code: 1010
LED:
EXT FLT
PMI Power Supply Fault Bit 12
The PMI Power Supply Fault bit is set if the
PMI power supply is not providing the
required output. Hex Value: 1000H
Sug. Var. Name: FLT_PS@

UDC Error Code: 1012
LED:
PWR OK
PMI Bus Fault Bit 13
The PMI Bus Fault bit is set if a problem is
detected with the address and data bus on
the PMI Regulator. Hex Value: 2000H
Sug. Var. Name: FLT_BUS@
Access: Read only
UDC Error Code: 1013
LED:
N/A
UDC Run Fault Bit 14
The UDC Run Fault bit is set if the UDC task
stops while the minor loop is running in the
PMI. Hex Value: 4000H
Sug. Var. Name: FLT_RUN@
Access: Read only
UDC Error Code: 1014
LED:
N/A
Communication Lost Fault Bit 15
The Communication Lost Fault bit is set if
the fiber-optic communication between the
PMI Processor and the UDC module is lost
due to two consecutive errors of any type. Hex Value: 8000H
Sug. Var. Name: FLT_COM@
Access: Read only
UDC Error Code: 1015
LED:
COMM OK
This bit is set only after communication between the PMI Regulator and UDC
module has been established. This bit should be used in the run permissive logic for
the drive. Also refer to the CCLK Synchronized bit (register 200/1200, bit 14).
