M420 General Flux Vector Control Inverter Basic Reference Guide

The capacitor or surge absorber can’t be connected to the output side of the inverter, or it may
damage the inverter.
If the motor cable is too long, for the influence of the distribute capacitance, it’s easily to
have electrical resonance, causing the damage of the insulation or large leakage current which
make the inverter over-current protection. If the length of motor cable is more than 100m, a AC
output reactor should be installed near the inverter.
