Configuring the UDC Module’s Registers

3-27

Drive Fault Register (Continued) 202/1202

DC Bus Overcurrent Fault Bit 1

The DC Bus Overcurrent Fault bit is set if

DC bus current exceeds 125% of the

Rectifier’s rated DC bus current.

Hex Value: 0002H

Sug. Var. Name: FLT_DCI@

Access: Read only

UDC Error Code: 1020

LED: P.M. FLT

Instantaneous Overcurrent Fault Bit 3

The Instantaneous Overcurrent Fault bit is

set if a power device overcurrent or

shoot-through fault occurs.

Hex Value: 0008H

Sug. Var. Name: FLT_IOC@

Access: Read only

UDC Error Code: 1017

LED: P.M. FLT

Power Device Status registers 204/1204, 220/1220, and 221/1221 indicate faults in

Power Modules A, B, or C, respectively. If a single power module is used, only

Bits 0 - 5 in the appropriate status register are set to indicate which power devices

produced the fault. In the event of a shoot-through fault, bit 6 is set as well. Refer the

descriptions of these registers for further information.

Local Power Interface Fault Bit 4

The Local Power Interface fault bit is set if

the power supply for the LPI module is not

operating within tolerance.

Hex Value: 0010H

Sug. Var. Name: FLT_LPI@

Access: Read only

UDC Error Code: 1022

LED: P.M. FLT

Gate Driver Interface Fault Bit 5

The Gate Driver Interface Fault bit is set if

the power supply on the Gate Driver

Interface (GDI) module is not operating

within tolerance.

Hex Value: 0020H

Sug. Var. Name: FLT_GDI@

Access: Read only

UDC Error Code: 1023

LED: OK on GDI

module

If power modules are connected in parallel, bit 7 in register 204/1204, 220/1220, or

221/1221 is set to indicate which GDI module is affected.
