Description of fault
Possible cause/remedy
18
Excess frequency con-
verter temperature appli-
cation
Inner temperature too high
Insufficient cooling, low
motor speed and high
torque, clocking frequency
too high
21 Bus
time-out
No answer from bus sharing unit
or MMI/PC
Check bus wiring
22 Confirmation
error
The number of maximum auto-
matic confirmations (1,182) was
exceeded
Check error history and
remedy error
23
External fault 1
The parameterised fault input is
active. 5.010
Correct the external fault
23
External fault 2
The parameterised fault input is
active. 5.010
Correct the external fault
32 Trip
IGBT
Protection of the IGBT module
against overcurrent has been
triggered
Short circuit in the motor
or motor feed line / con-
troller settings
33
Overvoltage of interme-
diate circuit
The maximum intermediate cir-
cuit current has been exceeded
Feedback by motor in
generating operation /
mains voltage too high /
faulty setting for rotation
speed control
34
Undervoltage of interme-
diate circuit
The minimum intermediate cir-
cuit current has not been
reached
Mains voltage too low
35
Excess motor temperature Motor PTC has been triggered
Overload of the motor
(e.g. high torque at low
motor speed) / ambient
temperature too high
36 Power
failure
A phase is missing / mains
voltage has been disrupted
38
Excess IGBT module tem-
perature
Excess IGBT module temperature Insufficient cooling, low
motor speed and high
torque, clocking frequency
too high
39 Overcurrent
Maximum output current of the
converter exceeded
40
Excess frequency con-
verter temperature
Inside temperature too high
Insufficient cooling, low
motor speed and high
torque, clocking frequency
too high
42 I
2
T motor safety shut-off
The internal I2T motor protec-
tion (can be parameterised) has
been triggered
Long-term overload
