Drive is immediately disabled, mo-
tor coasts to standstill.
▶ The error E44 is triggered in case of
wrong current feed of the motor dur-
ing operation without sensor.
▶ Faulty parameters entered for the
motor or faulty dimensioning of the
motor. The error depends on the dri-
ve function. For details refer to the
corresponding setup instructions.
Short circuit in power output stage Short circuit of the power output stage
due to:
1 Internal short circuit 1 Faulty drive control
2 (VCE) desaturation detection 2 Wrong parameters, output stage
defective, broken cable, short cir-
cuit etc.
3 Short to ground 3 Short to ground of a motor phase
4 Current measuring range 4 Wrong parameters, output stage
defective, broken cable, short cir-
cuit etc.
E45
(0x52D)
(1325d)
5 Overload motor
Drive is immediately disabled, mo-
tor coasts to standstill.
5 Drive function V/f: incorrect para-
meter setting of “Flying restart”
1 Safety circuit (Safety X10) 1 Safety circuit STO is activated
when the output stage is active; in-
put SAFE A and/or input SAFE B
were triggered.
2 Initialization error: internal
hardware of safety controller
2 Safety function SFM/SLOF: error in
according hardware components of
the safety controller
3 Incorrect data/parameters in
process sequence
3 Safety function SFM/SLOF: faulty
PLC telegrams
4 Error in function parameters
for a functional part
4 Safety function SFM/SLOF: para-
meter is out of limits
5 Timeout of monitoring func-
tions
5 Safety function SFM/SLOF: error in
according hardware components
6 Monitoring of OSSD signals
and output stage enable
6 Safety function SFM/SLOF:
▶ wrong OSSD signals
▶ defective OSSD relay
▶ defective multiplexer
7 Monitoring of motor phases 7 Safety function SFM/SLOF: defec-
tive motor cable (broken cable)
E46
(0x52E)
(1326d)
8 Frequency exceeded
Drive is immediately disabled, mo-
tor coasts to standstill without con-
trol.
8 Safety function SFM/SLOF:
▶ set reference speed value is too
high
▶ limit value for Safe Limited Out-
put Frequency is parameterized
incorrectly
▶ OSSD signals are set incorrect-
