This parameter is used to select the deceleration ramp as
follows:
0 (Term. inputs) (SEL): Selection of the deceleration ramp
via digital input. The choice of ramp comes from the binary
sum in menu 9 (
9.32
).
1 (Deceler.1) (Dec1): Deceleration ramp 1
2 (Deceler.2) (Dec2): Deceleration ramp 2
3 (Deceler.3) (Dec3): Deceleration ramp 3
4 (Deceler.4) (Dec4): Deceleration ramp 4
5 (Deceler.5) (Dec5): Deceleration ramp 5
6 (Deceler.6) (Dec6): Deceleration ramp 6
7 (Deceler.7) (Dec7): Deceleration ramp 7
8 (Deceler.8) (Dec8): Deceleration ramp 8
9 (To preset) (rP.Pr): The ramp is automatically associated
with the corresponding preset speed.
