2. Set terminal 27 to [0] No Operation
( 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 .
8. Set event 3 in parameter 13-51 SL Controller Event
to [30] Time Out 0 .
9. Set event 4 in parameter 13-51 SL Controller Event
to [0] False .
10. Set action 1 in parameter 13-52 SL Controller
Action to [10] Select preset 0 .
11. Set action 2 in parameter 13-52 SL Controller
Action to [29] Start Timer 0 .
12. Set action 3 in parameter 13-52 SL Controller
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.
