Motor overloaded
Check the following:
1. Load duty cycle must be correct
2. Motor nominal overtemperatures (P0626-P0628)
must be correct
3. Motor temperature warning level (P0604) must
match

temperature
signal lost
Open or short circuit of motor
temperature sensor. If signal loss is
detected, temperature monitoring
switches over to monitoring with the
motor thermal model.
Off1
F0020
Mains Phase
Missing
Fault occurs if one of the three input
phases are missed and the pulses
are enabled and drive is loaded
check the input wiring of the mains phases
Off1
F0021
Earth fault
Fault occurs if the sum of the phase
currents is higher than 5 % of the
nominal inverter current.
NOTE
This fault only occurs on inverters that
have 3 current sensors. Framesizes

fault
That hardware fault (P0947 = 22 and
P0949 = 1) caused by the following
events:
(1) DC-link overcurrent = short circuit
of IGBT
(2) Short circuit of chopper
(3) Earth fault
(4) I/O board is not poperly inserted.
Ø Framesize C (1),(2),(3),(4)
Ø Framesizes D to E (1),(2),(4)
Ø FramesizeF(2),(4)
Since all these faults are assigned to
one signal on the power stack, it is
notpossible to establish which one
actually occurred.
Check the I/O board. It has to be fully pressed home.
Off1
F0023
Output fault
Fault caused by the following events:
One phase of output is disconnected
Off1
F0024
Rectifier Over
Temperature
Ø Ventilation inadequate
Ø Fan inoperative
Ø Ambient temperature is too high.
Check the following:
1. Fan must turn when inverter is running
2. Pulse frequency must be set to default value
3. Ambient temperature could be higher than
specified for the inverter
Off1
F0030
Fan has failed
Fan no longer working 1. Fault cannot be masked while options module
(AOP or BOP) is connected.
2. Need a new fan.
