When using mains chokes, take their effect on the connected drive control‐
lers into account. Due to their inductance, mains chokes have a smoothing
effect on the current and thereby reduce harmonics.
Take the nominal current of the mains choke into account to have the induc‐
tance of the mains choke available.
Some mains chokes are assigned to certain drive controllers (see technical
data of the drive controller "Data for mains voltage supply → Assigned type of
mains choke").
Required data:
● Nominal current I
