D.6 Reactor
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. When a VFD is used to drive
