Table 5-1 Fault Messages

 

 

FAULT MESSAGE

DESCRIPTION

 

 

Invalid Base ID

Failure to determine control horsepower and input voltage configuration from the Power

 

Base ID value in software.

NV Memory Fail

Failure to read or write to non-volatile memory.

Param Checksum

Parameter Checksum error detected.

Low INIT Bus V

Low bus voltage detected on startup.

HW Desaturation

High output current condition detected (greater than 400% of rated output current). On B2

 

size controls, a desat error can indicate any of the following: low line impedance, brake

 

transistor failure or internal output transistor overtemperature.

HW Surge Current

High output current condition detected (greater than 250% of rated output current).

HW Ground Fault

Ground Fault detected (output current leakage to ground).

HW Power Supply

Control Board power supply failure detected.

Hardware Protect

A general hardware fault was detected but cannot be isolated.

1 MIN Overload

Peak output current exceeded the 1 minute rating value.

3 SEC Overload

Peak output current exceeded the 3 second rating value.

Overcurrent

Continuous current limit exceeded.

BUS Overvoltage

High DC Bus voltage.

Bus Undervoltage

Low DC Bus voltage condition detected.

Heat Sink Temp

Control heatsink exceeded upper temperature limit. For size B2 controls, this fault may

 

indicate the main heatsink or the gate drive circuit board is too hot.

External Trip

Connection between J4-16 and J4-17 is open.

New Base ID

Control board detected a change in the Power Base ID value in software.

REGEN RES Power

Excessive power dissipation required by Dynamic Brake Hardware.

Line REGEN

Fault in Line REGEN converter unit - Series 21H Line REGEN Inverter control.

EXB Selection

Expansion board not installed to support the selected Level 1 Input Block, Command

 

Select parameter.

Torque Proving

Unbalanced current in the three phase motor leads.

Unknown FLT Code

Microprocessor detected a fault that is not identified in the fault code table.

∝ P RESET

A software watchdog timer has reset the processor because a process has timed out.

FLT Log MEM Fail

Corrupt data in fault log (may occur on older systems only).

Current SENS FLT

Failure to sense phase current.

Bus Current SENS

Failure to sense bus current.
