D.6 Reactors
When the distance between the VFD and the motor is too long, the large parasitic capacitance to
ground produces high harmonic current, which causes the VFD to frequently enable overcurrent
protection and even causes motor insulation damage.
You must configure the output reactor nearby the VFD when the cable length is equal to or greater
than the values in the following table.

Note:

When one VFD drives multiple motors at the same time, you are advised to take the sum of
cable lengths of all motors as the total motor cable length.
