7.3.2 Installation of AC Input Reactor on Power Input Side
An AC input reactor is installed to eliminate the harmonics of the input current. As an optional
device, the reactor can be installed externally to meet strict requirements of an application
environment for harmonics.
7.3.3 Installation of AC Output Reactor on Power Output Side
Whether to install an AC output reactor on the power output side is dependent on the
actual situation. The cable connecting the AC drive and the motor should not be too long;
capacitance enlarges when an over-long cable is used and thus high-harmonics current
may be easily generated.
If the length of the output cable is equal to or greater than the value in the following table,
install an AC output reactor on the power output side of the AC drive.
