High-function General-purpose Inverter RX2 Series User’s Manual
Precautions for Correct Use
• The operation at power-on is the same as that of the restart after reset stop which occurs
when the inverter recovers from reset.
• 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.
• In the case of [bb-41]=01, if the residual voltage generated by the motor cannot be detected,
the 0 Hz restart may take place.
Parameter
Set the start mode after a trip reset or a reset input via the [RS] terminal (input terminal function 028).
(Ex.1) Restart operation with 0 Hz: [bb-41]=00
