・To decrease high frequency electromagnetic noise, [bb101]
should be set small. To lower motor sound loudness, [bb101]
has to be set bigger.
・The carrier frequency may be internally limited depending on
the setting of Load type selection [Ub-03].
※(SH1-03410-H(SH1-1600H)toSH1-04810-H(SH1-2200H)support only
ND(normal duty)and LD(low duty)).
・For the sake of the inverter protection, the Automatic carrier
reduction [bb103] decreases the carrier in certain cases.
