Configuring the UDC Module’s Registers 3-41
Parallel Power Module B Status Register 220/1220
The bits in the Parallel Power Module B Status register indicate the status of the power devices in Power
Module B. 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, IPUB@, is set.
Phase U-Upper IOC B Bit 0
The Phase U-Upper B status bit is set if an
IOC or DSAT fault occurs in Power Module
B’s phase U, upper power device. Hex Value: 0002H
Sug. Var. Name: U_UPB@
Access: Read only
UDC Error Code: N/A
LED: N/A
Phase V-Upper IOC B Bit 1
The Phase V-Upper IOC B bit is set if an
IOC or DSAT fault occurs in Power Module
B’s phase V, upper power device. Hex Value: 0002H
Sug. Var. Name: V_UPB@
Access: Read only
UDC Error Code: N/A
LED: N/A
Phase W-Upper IOC B Bit 2
The Phase W-Upper B status bit is set if an
IOC or DSAT fault occurs in Power Module
B’s phase W, upper power device. Hex Value: 0004H
Sug. Var. Name: W_UPB@
Access: Read only
UDC Error Code: N/A
LED: N/A
Phase U-Lower IOC B Bit 3
The Phase U-Lower IOC B status bit is set if
an IOC or DSAT fault occurs in Power
Module B’s phase U, lower power device. Hex Value: 0008H
Sug. Var. Name: U_LOB@
Access: Read only
UDC Error Code: N/A
LED: N/A
Phase V-Lower IOC B Bit 4
The Phase V-Lower B status bit is set if an
IOC or DSAT fault occurs in Power Module
B’s phase V, lower power device. Hex Value: 0010H
Sug. Var. Name: V_LOB@
Access: Read only
UDC Error Code: N/A
LED: N/A
