Error detection and troubleshooting
Operating manual INVEOR 77
No. Error name Description of fault Possible cause/remedy
15 Stall detection The drive shaft of the motor is
stalled. 5.080 Remove the blockade
18 Excess frequency inverter
temperature application 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
automatic 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 /
controller settings
33 Overvoltage of
intermediate circuit
The maximum intermediate
circuit current has been
exceeded Feedback by motor in
generating operation /
mains voltage too high /
faulty setting for rotation
speed control
34 Undervoltage of
intermediate circuit
The minimum intermediate circuit
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
temperature 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 inverter
temperature Inside temperature too high Insufficient cooling, low
motor speed and high
torque, clocking frequency
too high
