3.2.4 Time based deceleration
Except the decelerating transfers from
"V3" to "V1" and
"V2" to "V1"
all other speed transfers are carried out
depending on the time.
After switching off the current speed setting, the
control device decelerates depending on the
time up to the highest speed still controlled and
according to the deceleration set with rounded
out transfers.

3.2.5 Distance-corrected deceleration of "V3", "V2" and "V1"
The control device is able to delay the switching
off of the running signals by a distance set.
It is possible to delay
"V3" by the path "S_DI3",.
"V2" by the path "S_DI2" and
"V1" by the path "S_DI1"
and then switch it off. ADVANTAGE:
In the shaft, the disconnecting tag of "V3" is set
as far as possible from the flush "V1". After the
desired running curve is available, the remaining
rat run is eliminated by introducing this value in
parameter S_DI3.
Furthermore, it is possible to correct the
disconnecting tag for the flush "V1" by means of
S_DI1.
