)
Power supply load monitoring ->
mains voltage too low
Power supply unit will be discon‐
nected from mains.
▶ DC link was not precharged to the
minimum  voltage  level  in  the  set
time  period;  mains  voltage  is
connected to the short-circuited DC
link

motor coasts to standstill.
▶ Error message from external power
supply  unit;  power  supply  is
switched off.

)
Overvoltage in DC link
Drive is immediately disabled,
motor coasts to standstill.
▶ No  ballast  resistor  is  connected  or
ballast  resistor  is  dimensioned  too
small, i.e. X41/X63 not connected

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.
▶ Wrong  parameters  entered  for  the
motor or wrong dimensioning of the
motorThe  error  depends  on  the
drive  function.  For  details,  refer  to
the  corresponding  setup  instruc‐
tions.
