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.
µP 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.
