・[AA-12] specifies in which direction (forward/reverse)
will be the rotation after pressing the RUN key in the
operation keypad.
・
[AA-13] changes the behavior of the STOP key of
keypad. When 01 (enable) (initial value) is set, the
STOP key performs stop operation regardless of the
run command selection. When stopping only with the
command selected in the run command selection,
change it to 00(disabled). If the run command selectin
[AA111] is set to 02(Keypad's RUN key), the STOP key
on the Keypad is valid regardless of the [AA-13]
setting.

・ In the case of an incorrect RUN command, [AA114] setting

・
In [AA115] setting, deceleration stop or free-run stop
can be selected when a stop command is executed.
・If input terminal 032[FRS] is active (ON), free-run stop is
possible.
・With [bb-40], a restart with the release of the [FRS], or a
restart operation that will be executed after the
free-run-stop operation will be selected.
・If it selected free-run-stop (the torque will be lost), it can
be configured to stop by inertia in case of the [E007]
overvoltage error occurs during deceleration.

・Generally for a light duty control (such as fans or pumps) , the
[V/f] control with fixed torque characteristics or the [V/f]
control with reducing torque characteristics similar to the
operation characteristics of fans and pumps is selected.
・For a magnet motor, select the sensorless vector control
(SM/PMM).

・Torque control is effective only when the AA121 setting is 08 to

・Pulse train position control is effective only when the AA121
setting is 10 and the AA123 setting is 01, And input trminal
073[STAT] is assignd and must be ON.
・Absolute position control is effective only when the AA121
setting is 10 and the AA123 setting is 02 or 03.
・For more information, contact to your supplier or local Hitachi
distributor or service station.
