carrier reduction
selection, 1st-motor
・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.

・Adjustment of the automatic reset that follows an error
event. In the case that RUN command was on
execution, after resetting, the motor re-operates
according to the setting of [bb-41] Restart mode after
RS release.
Retry/trip setting in error event

instantaneous power failure
bb-21

overcurrent
bb-23
Number of retries after over
voltage
・Set the number of times to retry after each error.
・If 0 is set, as soon as an error occurs, it will trip.
・To retry, set the value of these parameters other than 0.
