Defective phase current sensor or open circuit detected between control board and current
sensor.
DC Bus High
Bus over voltage condition occurred.
DC Bus Low
Bus under voltage condition occurred.
Feedback Loss
Check resolver connections; noise on resolver lines or resolver power supply loss.
External Trip
An external over temperature condition occurred or open circuit on J1-16.
Following ERR
Excessive following error detected between command and feedback signals.
GND FLT
Low impedance path detected between an output phase and ground.
INT Over-Temp
Temperature of control heatsink exceeded safe level.
Invalid Base ID
Control does not recognize power base ID.
Logic Supply FLT
Logic power supply not working properly.
Lost User Data
Battery backed RAM parameters have been lost or corrupted.
