C-2 Diagnositics, Troubleshooting, and Start-Up Guidelines
Faults Need Reset Bit 3
The Faults Need Reset bit is set if previous
faults (register 202/1202) have not been
cleared. Hex Value: 0008H
Sug. Var. Name: IC_FLT@
Access: Read only
UDC Error Code: N/A
LED: N/A
Rising Edge Required Bit 4
The Rising Edge Required bit is set if a
rising edge is not detected on a command
bit in register 100/1100. Hex Value: 0010H
Sug. Var. Name: IC_RISE@
Access: Read only
UDC Error Code: N/A
LED: N/A
This interlock bit will be set if the application task has set the Fault Reset bit (register
100/1100, bit 8) but has not cleared and then re-enabled any command bits.
More Than One Request Bit 5
The More Than One Request bit is set if
more than one operating mode is requested
at a time in register 100/1100 (bits 0, 1, 2). Hex Value: 0020H
Sug. Var. Name: IC_MORE@
Access: Read only
UDC Error Code: N/A
LED: N/A
Refer to the SA3100 Drive Configuration and Programming instruction manual
(S-3056) for more information.
Bus Not Ready Bit 6
The Bus Not Ready bit is set when turning
on the drive if the DC bus is not ready. Hex Value: 0040H
Sug. Var. Name: IC_BUS@
Access: Read only
UDC Error Code: N/A
LED: N/A
The bus is ready when the DC bus voltage is greater than the undervoltage
threshold value stored in local tunable UVT_E0% and has reached a steady state,
and feedback indicates that the pre-charge contactor has closed.
This interlock bit will also be set when turning on the drive if the bus enable bit
(register 100/1100, bit 4) has not been set. Refer to the SA3100 Power Modules
instruction manual (S-3058) for more information about internal DC bus control.
MCR Did Not Close Bit 7
The MCR Did Not Close bit is set if the
optional output contactor did not close when
commanded to do so. Hex Value: 0080H
Sug. Var. Name: IC_MCR@

UDC Error Code: N/A
LED: N/A
