speed 1 in 3 sec – ramp up to reference speed 0 and then continue sequencing until stop is applied.
Preparing for set-up:
Set the ramping times in par. 3-41 and 3-42 to the wanted times
Set term 27 to No Operation (par. 5-12)
Set Preset reference 0 to first preset speed (par. 3-10 [0]) in percentage of Max
reference speed (par. 3-03). Ex.: 60%
Set Preset reference 1 to first preset speed (par. 3-10 [1]) in percentage of Max
reference speed (par. 3-03). Ex.: 10%
Set preset reference 1 to second preset speed (par. 1-10 [1] Ex.: 10 % (zero).
Set the timer 0 for constant running speed in par. 13-20 [0]. Ex.: 2 sec.
Set the timer 1 for constant running speed in par. 13-20 [1]. Ex.: 3 sec.
Set Event 0 in par. 13-51 [0] to True [1]
Set Event 1 in par. 13-51 [1] to On Reference [4]
Set Event 2 in par. 13-51 [2] to Time Out 0 [30]
Set Event 3 in par. 13-51 [3] to On Reference [4]
Set Event 4 in par. 13-51 [4] to Time Out [30]
Set Action 0 in par. 13-52 [0] to Select preset 0 [10]
Set Action 1 in par. 13-52 [1] to Start Timer 0 [29]
Set Action 2 in par. 13-52 [2] to Select preset 1 [11]
Set Action 3 in par. 13-52 [3] to Start Timer 1 [30]
Set Action 4 in par. 13-52 [4] to No Action [1]
