(parameter 5-12 Terminal 27 Digital Input).
3. Set preset reference 0 to the first preset speed
(parameter 3-10 Preset Reference [0]) in percentage
of maximum reference speed
(parameter 3-03 Maximum Reference). For example:
60%.
4. Set preset reference 1 to the second preset speed
(parameter 3-10 Preset Reference [1] For example:
0% (zero).
5. Set the timer 0 for constant running speed in
parameter 13-20 SL Controller Timer [0]. For
example: 2 s.
6. Set event 1 in parameter 13-51 SL Controller Event
to [1] True.
7. Set event 2 in parameter 13-51 SL Controller Event
to [4] On Reference.

Action to [11] Select preset 1.
13. Set action 4 in parameter 13-52 SL Controller
Action to [1] No Action.
14. Set the smart logic control in parameter 13-00 SL
Controller Mode to [1] ON.
Start/stop command is applied on terminal 18. If a stop
signal is applied, the frequency converter ramps down and
enters free mode.
