This can only be set in the
AC, AC+DC, and Hz modes.
*1: The display value and output value are values that have been passed through a low-pass
filter (LPF) with cut-off frequencies (fc) around 180 Hz. With the filter function enabled, the
180 Hz components can be damped by -3 dB (approx. 30%). Use this function to remove
carrier components from the inverter output side (secondary side) or if noise is annoying you,
and in similar cases.
