HF commutating reactors

The matching HF commutating reactor, according to the selection table, is
required to connect the uncontrolled 28 kW infeed and the controlled
infeed/regenerative feedback modules to the line supply (refer to Section 6).
Commutating reactors have the following tasks:
S
Limit the amount of harmonics fed back into the line supply
S
Store energy for step-up controller operation in conjunction with infeed and
regenerative feedback modules
HF commutating reactor for line supplies 3-ph. 400 V AC -10 % to 480 V +6 %;
50/60 Hz $10 %
Note
When using commutating reactors, which SIEMENS has not released for
SIMODRIVE 6SN11, harmonics can occur which can damage/disturb other
equipment connected to the line supply.
