Table 5-1 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.
An open circuit on J1-16 typically indicating an external over temperature condition
occurred.
Low impedance path detected between an output phase and ground.
Temperature of control heatsink exceeded safe level.
Control does not recognize power base ID.
Control board installed on power base without current feedback.
Only applies to Series 21H and 22H Line Regen controls.
Logic power supply not working properly.
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.
Control board sensed a different power base since last time it was powered up.
Fault log is empty.
Programmed operating parameter requires an expansion board that is not installed or is
not recognized.
Instantaneous over current condition detected by bus current sensor.
Output current exceeded 1 minute rating.
Output current exceeded 3 second rating.
Motor RPM exceeded 110% of programmed MAX Motor Speed.
Power cycled before the residual Bus voltage reached 0VDC.
Desaturation of power device occurred or bus current threshold was exceeded. (On B2
size controls, a desat error can indicate any of the following: low line impedance, brake
transistor failure or excessive internal temperature at the output transistors.)
Regen power exceeded DB resistor rating.
Custom software operating fault occurred.
Co-Processor hardware fault occurred. Contact Baldor.
