Table 5-2 Power Output 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.
Encoder coupling slipping or broken; noise on encoder lines, encoder power supply loss or
defective encoder.
An open circuit on J1-16 typically indicating an external over temperature condition.
Excessive following error detected between command and feedback signals.
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.
Indicates a converter section fault.
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.
