2.3.6 Noise Filter
A noise filter installed on the power supply side eliminates noise leaking from the main circuit power line to
the Σ-V-SD driver. The filter also reduces the noise leaking from the Σ-V-SD driver to the main circuit power
line.
Use a noise filter designed to suppress harmonic noise. Do not use general-purpose noise filters, because their
effectiveness is minimal when used with the Σ-V-SD driver.
Install a noise filter at the input side of the power regeneration converter.

Some noise filters have large leakage currents. Leakage current is also greatly affected
by ground conditions. If you use a ground fault detector, consider the ground conditions
and the leakage current of the noise filter when you select one.
Ask the manufacturer of the noise filter for details.
