(Ex.4) Invalidating resetting at normal ([CA-72]=02,03)
(Ex.5) When frequency adjustment restarting is selected ([bb-41]=01)
In the “Reset restarting selection [bb-41],” selecting “01 (frequency adjustment restarting)” allows you to
perform the frequency adjustment restarting when turning on the power supply again. When “00
(Restarting with 0 Hz)” is set, the operation starts from 0 Hz without waiting for the “Retry stand-by time
for instantaneous power failure and insufficient voltage [bb-26].”
Precautions for Correct Use
Even when the frequency adjustment restarting is selected, the “Restarting with 0 Hz” occurs in
the cases shown below.
• When an output frequency is 1/2 of a base frequency or below
• When the induced voltage of the motor quickly attenuates
• When the “Lower limit setting for frequency adjustment [bb-42]” is set, and a frequency equal
to or below this set frequency is detected
