: Deceleration rate selector
Adjustment range :0 to 9
Factory setting :1
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.
to : Deceleration rates 1 to 8
Adjustment range :0.1 to 600.0 s/1000 rpm
Factory setting :5.0 s/1000 rpm
Sets the time for deceleration from 1000 rpm to 0.
2.21 to 2.28 =
2.21: Deceleration rate 1 (main ramp in factory settings)

Adjustment range :0 or 1
Factory setting :0
0 (ALL) (ALL): When 2.03 = 1, the ramp is always held.
1 (> V MIN) (S.Min): When 2.03 = 1, the ramp is freed
between 0 and V min (1.07).
