6.2 Faults and Alarms (Warnings)
Listed below are the Faults & Warnings that are most common. Other Fault and Alarm codes exist. If
you get one not included below – please refer to the Parameter List (on the CD that came with the
MM440 drive). It is also possible that further information exists in the Parameter list for the faults listed
below.
Fault /
Warning
Description Cause / Remedy
F0001 Overcurrent
• Motor cables are too long – fit output choke, or move drive closer to
motor.
• Short circuit in motor leads – locate and correct short circuit
• Ground fault present – Check and correct for ground faults
• Stator resistance value incorrect – perform motor ID on cold motor
(P1910=1)
• Motor is obstructed – remove obstruction
• Ramp up time is too short – lengthen ramp up time
• Boost level is too high – reduce boost level (P1310-P1312 for V/f,
P1610, P1611 for Vector control)
• Motor parameters are incorrect – re-perform Quick Commissioning
and enter corrected motor data)
• Motor too large for drive – get larger drive.
F0002 Overvoltage
• Line Voltage too high – check and correct line voltage to suit drive –
or get a drive to suit line voltage. Prolonged exposure to excessive
line voltage will damage the inverter.
• Too much regenerative energy – use VDC Max controller (P1240) to
lengthen ramp down times, manually increase ramp down times or fit
a braking resistor. The ramp down time has to match the inertia of
the load
• Voltage spikes on line voltage – add a line reactor.
F0003 Undervoltage
• Line supply too low – check and correct line voltage to suit drive – or
get a drive to suit line voltage.
• Line supply interruption – a power outage when the drive is running
– ensure stable supply.
• Shock load outside of specification (1ph drives only) – ensure that
load is suitable for the drive.
F0004
Inverter
Overtemperature
• Ventilation is inadequate – improve ventilation – See section 1.2 for
further details
• Ambient temperature is too high – ensure that ambient temperature
is within the limits defined for the drive.
• Fan is obstructed – remove obstruction
• Fan is defective – replace fan
F0005 Inverter I2T (overload)
• Drive is overloaded – load needs to be reduced – or a larger drive
should be used.
• Duty cycle too demanding – load needs to be reduced or larger drive
should be used.
• Motor too large for drive – load needs to be reduced or larger drive
should be used.
