Configuring the UDC Module’s Registers

3-33

Drive Fault Register (Continued) 202/1202

Ground Current Fault Bit 2

The Ground Current Fault bit is set if ground

current exceeds the hardware trip point.

Hex Value: 0004H

Sug. Var. Name: FLT_GND@

Access: Read only

UDC Error Code: 1021

LED: EXT FLT

For models A001/Q001 and A003/Q003 the hardware trip point is 20A @ 10V.

For all other models it is 100A @ 10V.

Instantaneous Overcurrent Fault Bit 3

The Instantaneous Overcurrent (IOC) Fault

bit is set if either of the following conditions

is detected:

Hex Value: 0008H

Sug. Var. Name: FLT_IOC@

Access: Read only

UDC Error Code: 1017

LED: P.M. FLT

• Output current is greater than 200% of the peak RMS current. Bits 0 to 5 in

• An inverter power device fault is detected. Bit 6 in register 204/1204 will be set if

the IOC fault is due to a power device overcurrent.

Power Supply Fault Bit 4

The Power Supply Fault bit is set if the

output of the isolated +12V supply, or the

output of the external power supply for a G

or H frame drive, falls below the configured

low voltage threshold.

Hex Value: 0010H

Sug. Var. Name: FLT_12V@

Access: Read only

UDC Error Code: 1022

LED: P.M. FLT

Bit 5

Reserved for future use.

Hex Value: 0020H

Sug. Var. Name:

Access: Read only

UDC Error Code: 1023

LED:
