12.27.2.2 Setting acceleration and deceleration times
The speed setpoint is led via a ramp function generator. This enables input steps to be
converted into a ramp.
The acceleration time (T
ir
) and deceleration time (T
if
) refer to a change in speed from "0"
to n
max
(0 ... 100%). The times to be set are calculated according to the formulae:
Acceleration time (code C0012) Deceleration time (code C0013)

In C0101/1 ... 15 and C0103/1 ... 15, 15 time pairs (T
i
times) can be stored additionally. Via
the inputs SPEED−NSET.TIx (C7411/13 ... C7411/16) the T
i
times can be activated:
