(Ex.4) Frequency pull-in [bb-40]=01 to 03
Precautions for Correct Use
• The restart after reset, which occurs when the inverter recovers from a reset, is the same as
the mode at power-on.
• If the frequency pull-in restart is used, the rotational direction of the output frequency is the
same as that of the frequency command.
• If a power failure lasts long and the inverter’s internal power supply is lost, recovery will take
place by the restart after reset instead of the restart after instantaneous power fail-
ure/under-voltage.
• At power-on, the inverter will start operation with 0 Hz.
• In case of the 0 Hz restart, there is no wait time.
(Ex.5) and (Ex.6) below show cases where the free-run stop is performed via the operation command.
The free-run stop at stopping is used when an overvoltage error occurs at stopping, for example. How-
ever, the motor continues rotating through inertia.
