Group 22: Accel/Decel
Two acceleration/deceleration ramp pairs can be used. If both ramp pairs are
used, selection can be made between these in run time through a digital
input. The S curve of the ramps is adjustable.

The first ramp pair is used (
1...5 = DI1...DI5
Ramp pair selection is done through a digital input (DI1 to DI5).
Digital input deactivated = Ramp pair 1 (
used.
Digital input activated = Ramp pair 2 (
Note! Ramp pair selection is not followed under serial link control.
