lower values.
D.6 Reactors
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 inverter 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 inverter 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 inverter is used to drive 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 inverter. If the
distance between the inverter 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 IMO's technical support technicians.
