The AC drive can be forced to stop state from keypad stop button even if it is controlled from
another control place (
Remote ). If this measure is taken, the drive goes to the alarm state and
cannot be restarted from the remote control place before the start button has been pressed
(while in
Remote ).
You can still momentarily switch to Local and start there but when going back to Remote a start
button press is needed. This also applies after a power-down as the state of this function is re-
tained in memory.
The function can be enabled or disabled with this parameter.

RESET FREQUENCY MODE
You can use the preset frequency parameters to define certain frequency references in ad-
vance. These references are then applied by activating/inactivating digital inputs connected to
parameters M3.5.1.16, M3.5.1.17 and M3.5.1.18 ((
Preset frequency selection 0, Preset fre-
quency selection 1 and Preset frequency selection 2 ). Two different logics can be selected:
M3.3.11

The values of the preset frequencies are automatically limited between the minimum and max-
