When the voltage of the grid is high, the transient large current that flows into the input power
circuit may damage rectifier components. You need to configure an AC reactor on the input
side, which can also improve the current adjustment coefficient on the input side.
When the distance between the VFD and motor is longer than 50 m, the parasitic capacitance
between the long cable and ground may cause large leakage current, and overcurrent
protection of the VFD may be frequently triggered. To prevent this from happening and avoid
damage to the motor insulator, compensation must be made by adding an output reactor. 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.
