Table 6.A – Bulletin 160 Fault Descriptions (continued)
Fault
Number
Fault
Indication
Fault Description Corrective Action
06 Motor Stall
Fault
Motor has stalled. Motor load is excessive. Longer acceleration time or a reduced load
required.
07 Motor
Overload
Fault
Internal electronic overload trip. Excessive
motor load exists.
Reduce motor load until controller output current
does not exceed the current set by P42 – [Motor
Overload Current]. Reduce P38 – [Boost
Select].
08 Over
Temperature
Fault
Excessive heat detected. Clear blocked or dirty heat sink fins. Check
ambient temperature. Check for blocked or
non-operating fan.
11 Operator
Fault
Keypad has been removed while controller is
powered.
Clear fault. Do not remove keypad under power.
12 Overcurrent
FauIt
Overcurrent detected in hardware trip circuit. Check short circuit at the controller output or
excessive load conditions at the motor.
32 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].
