Drive is immediately disabled,
motor coasts to standstill.
The error E44 is triggered in case of
wrong current feed of the motor during
operation without sensor.
Possible reason: wrong parameter
setting or overload of the motor. The
error depends on the drive function. For
details refer to the corresponding setup
instructions.
