Installation and selection
Function Definition
DC reactor
Installed between the EMC filter and
the braking resistor
132kW and above standard
Increase the power factor on the input side;
Improve the overall efficiency and thermal stability of the AC Drive;
Effectively eliminate the influence of the input side higher harmonics on the
AC Drive and reduce external conduction and radiation interference.
Break unit
Standard 22kW and below, 22kW or
more to 110kW (connected between
PB and (+))
For power models above 22kW, please choose our recommended braking
unit and braking resistor;
The motor consumes regenerative energy through the braking resistor
when decelerating.
