Part description
AC reactor
EMI filter
(Note)
DC reactor
Radio noise filter
Motor filter
Note: Usage of an EMI filter (e.g. one from the FPFL100 series) is
necessary for the European EMC directive, for the Australian C-TICK
and others. In comparison, the other parts mentioned in the table above
are not intended for this special use.

This part is used when the unbalance ratio is 3% or
more and the power supply is 500kVA or more, and
there are rapid changes in the power supply. This part
also improves the power factor.
This part ist used to conform with the applicable
This part is used to improve the power factor.
This part reduces noise generated at the output of the
inverter (this type of filter supplies an almost perfect
sine shaped output voltage between phase-pase and
Motors that are driven by an inverter are to a larger
extent subject to voltage fluctuations than motors directly
driven (without inverter) by power lines. An AC reactor
installed between inverter output and motor smoothens
motor run and so reduces torque ripple. When the cable
between the inverter and the motor is too long, this part
also forces the voltage dv/dt to be limited and so protects
the isolation of the motor.
