Table 5: List of Fault Messages (F) and Warning Messages (AL)
Display Designation Possible Cause Instructions
01 Overcurrent • The adjustable frequency drive has
detected an excessive current (> 4 x I
N
)
in the motor cable
• Sudden load increase
• Short circuit in motor cable
• Inadequate motor
• Check the load
• Check the motor size
• Check the cable
(
parameter P6.6)
02 Overvoltage • The DC bus voltage has exceeded
the internal safety limit
• The delay time is too short
• High overvoltage peaks in line power
Increase braking time
03 Ground fault • An additional leakage current was
detected when starting by means of
a current measurement
• Insulation fault in the cables or in
the motor
Check the motor cable and
the motor
08 System fault • Component fault
• Malfunction Reset the fault and restart.
If the fault occurs again, please
contact your Eaton representative
or call 877-ETN-CARE (386-2273).
09 Undervoltage The DC bus voltage is operating below
voltage level.
Probable cause:
• The supply voltage is too low
• Internal device fault
• Power failure • If a brief power failure takes
place, reset the fault and restart
the adjustable frequency drive
• Check the supply voltage. If it is
OK, there is an internal fault.
If this is the case, please contact
your Eaton representative or
call 877-ETN-CARE (386-2273).
13 Under-
temperature The IGBT switch temperature is below
–10ºC. Check the ambient temperature
14 Over-
temperature The IGBT switch temperature is above
120ºC. An excessive temperature
warning is issued if the IGBT switch
temperature goes above 110ºC. • Make sure that there is an
unobstructed flow of
cooling air
• Check the ambient temperature
• Make sure that the switching
frequency is not too high in
relation to the ambient
temperature and to the
motor load
15 Stall protection The motor blocking protection
mechanism has been triggered.
Check the motor
16 Motor over-
temperature The adjustable frequency drive’s motor
temperature model has detected motor
overheating. The motor is overloaded. Decrease the motor load.
If the motor is not overloaded,
check the temperature model
parameter.
22 EEPROM

error • Error when storing parameters
• Malfunction
• Component fault
• Error in microprocessor monitoring Please contact your Eaton
representative or
call 877-ETN-CARE (386-2273).
25 Watchdog • Error in microprocessor monitoring
• Malfunction
• Component fault Reset the fault and restart.
If the fault occurs again, please
contact your Eaton representative
or call 877-ETN-CARE (386-2273).
