EEPROM
Fault
EEPROM has invalid data.
Reset EEPROM using P56 – [Reset Functions].
Set to 1. Cycle power.
33
Max Retries
Fault
Controller failed to reset fault within the number
of retries set in P50 – [Restart Tries].
Repair system fault.
38
Phase U Fault Phase to ground fault detected between
controller and motor in phase U.
Check the wiring between the controller and
motor. Check motor for grounded phase.
39
Phase V Fault Phase to ground fault detected between
controller and motor in phase V.
Check the wiring between the controller and
motor. Check motor for grounded phase.
40
Phase W
Fault
Phase to ground fault detected between
controller and motor in phase W.
Check the wiring between the controller and
motor. Check motor for grounded phase.
41
UV Short
Fault
Excessive current has been detected between
these two controller output terminals.
Check the motor and external wiring to the
controller output terminals for a shorted condition.
42
UW Short
Fault
Excessive current has been detected between
these two controller output terminals.
Check the motor and external wiring to the
controller output terminals for a shorted condition.
43
VW Short
Fault
Excessive current has been detected between
these two controller output terminals.
Check the motor and external wiring to the
controller output terminals for a shorted condition.
48
Reprogram
Fault
Occurs when controller parameters are reset to
defaults.
Clear fault.
49
Zero
Overload
Fault
Occurs when load requires excessive current at
zero hertz, or P38 – [Boost Volts] set too high.
Reduce motor load at zero hertz. Reduce motor
dwell time at zero hertz. Reduce P38 – [Boost
Volts].
