6.7 Selection of the AC Output Reactor
Whether to install an AC output reactor on the output side is dependent on actual
situations. The cable connecting the AC drive and motor cannot be too long. Otherwise,
capacitance enlarges and thus high-harmonics current may be easily generated.
To avoid these problems, install an AC output reactor close to the AC drive if the cable
length is greater than or equal to the values listed in the following table.
