The acceleration and deceleration time are different, that is, the ramp-up and fall-time parameters P1120 and P1121 are different. P1120 and P1121 themselves belong to the drive data set (DDS). The three different sets of DDS switch selection function parameters are: P820, P821.
P700=2 p1000=3
P701=16[terminals 5 and 9, switch 1] p1001.0=speed 1 p1001.1=speed 2 p1001.2=speed 3
P702=99 [terminals 6 and 9, switch 2] (speed 2) p820=722.1
P703=99 [terminals 7 and 9, switch 3] (speed 3) p821=722.2
P1120.0 = acceleration time of speed 1, p1121.0 = deceleration time of speed 1.
P1120.1=acceleration time of speed 2,p1121.1=deceleration time of speed 2
P1120.2=acceleration time of speed 3, p1121.2=deceleration time of speed 3
Only switch 1 is switched on Select speed 1
Switch 2 is switched on or switch 3 is switched on or switches 2 and 3 are switched on together, no fixed frequency is selected ie no switch 1 is selected, speed is 0
Turn switch 1 on and switch 2 on, select speed 2
Turn switch 1 on and switch 3 on, select speed 3
Switch 1.2.3 are on, the choice is speed 3
