Table 5-1 Converter Control Board Fault Messages
Defective phase current sensor or open circuit detected between control board and current
sensor.
Bus over voltage condition occurred.
Bus under voltage condition occurred.
Low impedance path detected between an output phase and ground.
Phasing between main power connections, zero crossing detectors, line reactor and
control does not match.
Control board installed in power base that does not have current feedback and current
feedback is required.
Temperature of control heatsink exceeded safe level.
Control does not recognize power base ID.
Logic power supply not working properly.
Missing phase detected by P.
Missing phase detected by P.
Battery backed RAM parameters have been lost or corrupted.
When fault cleared (Reset), the control should reset to factory preset values.
Insufficient bus voltage on startup.
EEPROM error occurred. Contact Baldor.
Watchdog timer detected error.
Control board sensed a different power base since last time it was powered up.
Fault log is empty.
Instantaneous over current condition detected by bus current sensor.
Output current exceeded allowable rating.
Desaturation of power device occurred or bus current threshold exceeded.
Incorrect line phasing or frequency detected on startup.
