3.5.4 Sinusoidal filter
A sinusoidal filter is used to provide a better quality waveform to the motor, reducing motor noise,
temperature and mechanical stress. It will reduce or eliminate harmful dV/dt values (voltage rise
over time) and voltage doubling effects which can damage motor insulation. This effect occurs
most noticeably when using very long motor cables, for example 30m (100 ft) or more. Baldor
motors intended to be used with drives are designed to withstand the effects of large dV/dt and
overvoltage effects. However, if very long motor cables are unavoidable and are causing
problems, then a sinusoidal filter may be beneficial.
