select accessories based on the actual market conditions, but try not to use those with lower
values.
D.6 Harmonic filter
To enhance grid protection, reduce harmonic interference from the VFD to the grid, and
improve input power factor, consider configuring external DC reactors, input reactors, or
passive harmonic filters based on your specific application needs.
If you want to use long cables between the VFD and the motor, select external output reactors,
dv/dt attenuation filters, or sine-wave filters based on the motor cable length. This helps
mitigate excessive dv/dt, reducing voltage stress on the motor windings as well as protecting
them, and extending the motor's lifespan. Refer to the table below for recommended output
filter selections according to motor cable length.
