No. Error name Description of error Possible causes/remedy
22 Acknowledgement error The number of maximum automatic
acknowledgements (1.182) was ex-
ceeded Check error history and remedy error
23 External fault 1 The parameterised fault input is active.
5.010 Correct the external fault
24 External fault 2 The parameterised fault input is active.
5.011 Correct the external fault
25 Motor detection Motor identification error Check variable-frequency drive/motor
and PC / remote control / variable-
frequency drive connections / restart
motor identification
26 STO inputs plausibility The statuses of the two STO inputs
have not been identical for more than
2 sec. Incorrect activation of the STO inputs
Check corresponding external wiring
32 Trip IGBT Protection of the IGBT module against
overcurrent has been triggered Short circuit in the motor or motor
feed line / controller settings
33 Overvoltage of intermediate
circuit The maximum intermediate circuit
voltage has been exceeded Feedback by motor in generator
mode / mains voltage too high /
faulty setting for rotation speed con-
troller / brake resistor not connected
or defective / ramp times too short
34 Undervoltage of intermediate
circuit The minimum intermediate circuit
voltage has not been reached Mains voltage too low, mains connec-
tion defective / check wiring
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 The grid voltage has dropped briefly Grid fluctuation / grid voltage inter-
rupted
38 Excess IGBT module temper-
ature Excess IGBT module temperature Insufficient cooling, low motor speed
and high torque, switching frequency
too high
39 Overcurrent Maximum output current of variable-
frequency drive exceeded Motor stalled / check motor connec-
tion / incorrect speed controller set-
ting / check motor parameters / ramp
times too short / brake not open
40 Excess frequency converter
temperature Inner temperature too high Insufficient cooling / low motor speed
and high torque / switching frequency
too high permanent overload / reduce
ambient temperature / check fan
42 I2t motor protection shutoff The internal I2t motor protection (can
be parameterised) has been triggered Permanent overload
43 Ground leak Ground leak during a motor phase Insulation fault
45 Motor connection disrupted No motor current in spite of control
through frequency converter No motor connected or not com-
pletely connected
Check phases or motor connections
and connect correctly when necessary
46 Motor parameters Plausibility check for motor parameters
failed Parameter set not OK
47 Variable-frequency drive
parameters Plausibility check for variable-fre-
quency drive parameters failed Parameter set not OK, motor type
33.001 and control method 34.010
not plausible
48 Type plate data No motor data entered Please enter the motor data according
to the motor nameplate
