Configuring the UDC Module’s Registers 3-43
Parallel Power Module B Status Register (Continued) 220/1220
Phase U Current Sharing B Bit 13
The Phase U Current Sharing B bit is set if a
Power Module B is not carrying its share of
the phase U current. Hex Value: 2000H
Sug. Var. Name: U_SHRB@
Access: Read only
UDC Error Code: N/A
LED: N/A
Phase V Current Sharing B Bit 14
The Phase V Current Sharing B bit is set if
Power Module B is not carrying its share of
the phase V current. Hex Value: 4000H
Sug. Var. Name: V_SHRB@
Access: Read only
UDC Error Code: N/A
LED: N/A
Phase W Current Sharing B Bit 15
The Phase W Current Sharing B bit is set if
Power Module B is not carrying its share of
the phase W current. Hex Value: 8000H
Sug. Var. Name: W_SHRB@
Access: Read only
UDC Error Code: N/A
LED: N/A
Parallel Power Module C Status Register 221/1221
The bits in the Parallel Power Module C Status register indicate the status of the power devices in power
Module C. This register is used only when two or more power Modules are connected in parallel.
If an IOC (overcurrent) fault is detected, the associated phase upper and lower status bits are set. If a phase
DSAT (shoot-through) fault is detected, the associated phase status bits are set and the Intelligent Power
Module bit, IPUC@, is set.
Phase U-Upper IOC C Bit 0
The Phase U-Upper C status bit is set if an
IOC or DSAT fault occurs in Power Module
C’s phase U, upper power device. Hex Value: 0002H
Sug. Var. Name: U_UPC@
Access: Read only
UDC Error Code: N/A
LED: N/A
Phase V-Upper IOC C Bit 1
The Phase V-Upper IOC C bit is set if an
IOC or DSAT fault occurs in Power Module
C’s phase V, upper power device. Hex Value: 0002H
Sug. Var. Name: V_UPC@
Access: Read only
UDC Error Code: N/A
LED: N/A
