・
To decrease noise, [bb101] should be set small. To lower
electromagnetic sound, [bb101] has to be set bigger.
・
By setting the duty specification selection [Ub-03], the
carrier frequency is internally limited.
・
For the sake of the inverter protection, the Automatic
carrier reduction [bb103] decreases the carrier in
certain cases.

execution, after the reset, is followed by the setting of
[bb-41].

If you want to reset the retry count, assign any value
other than 0.

・
When using Intelligent input terminals [FRS] and [RS],
restart mode can be selected.
・
[bb-40] allows you to select the restart operation after a
free-run stop.
・
[bb-41] allows you to select the restart operation after a
trip or reset event.

・
The matching frequency function adopts the motor
frequency for a shockless start-up.
・
If at the restart the frequency is under the [bb-42]
frequency, a 0Hz restart will be used instead.
