multiple motors, take the total length of the motor cables (that is, sum of the lengths of the motor
cables) into account. When the total length is longer than 50 m, an output reactor must be added on
the output side of the VFD. If the distance between the VFD and motor is 50 m to 100 m, select the
reactor according to the following table. If the distance is longer than 100 m, contact INVT's technical
support technicians.
DC reactors can be directly connected to VFDs of 380V 0132 or higher and the 660V series. DC
reactors can improve the power factor, avoid damage to bridge rectifiers caused due to large input
current of the VFD when large-capacity transformers are connected, and also avoid damage to the
rectification circuit caused due to harmonics generated by grid voltage transients or phase-control
loads.
