3-82 Quick Stop Ramp Type
Option:
Function:
Select the ramp type, depending on
requirements for acceleration and
deceleration. A linear ramp will give
constant acceleration during ramping. An
S-ramp will give non-linear acceleration,
compensating for jerk in the application.

3-83 Quick Stop S-ramp Ratio at Decel. Start
Range:
Function:
50 %
*
[ 1 - 99.
%]
Enter the proportion of the total ramp-down
time (
) where
the deceleration torque increases. The larger
the percentage value, the greater the jerk
compensation achieved, and thus the lower
the torque jerks in the application.
3-84 Quick Stop S-ramp Ratio at Decel. End
Range:
Function:
50 %
*
[ 1 - 99.
%]
Enter the proportion of the total ramp-down
time (
3-42 Ramp 1 Ramp Down Time
) where
the deceleration torque decreases. The
larger the percentage value, the greater the
jerk compensation achieved, and thus the
lower the torque jerks in the application.
3.5.8 3-9* Digital Pot.Meter
The digital potentiometer function allows the user to
increase or decrease the actual reference by adjusting the
set-up of the digital inputs using the functions
Increase
,
Decrease
or
Clear
. To activate the function, at least one
digital input must be set up to
Increase
or
Decrease
.

. If
INCREASE/DECREASE is activated the
resulting reference will be increased/
decreased by the amount set in this
parameter.
3-91 Ramp Time
Range:
Function:

*
[0.00 -
3600.00 s]
Enter the ramp time, i.e. the time for
adjustment of the reference from 0% to
100% of the specified digital potentiometer
function (Increase, Decrease or Clear).
If Increase/ Decrease is activated for longer
than the ramp delay period specified in
the actual reference will be
ramped up / down according to this ramp
time. The ramp time is defined as the time
used to adjust the reference by the step size
specified in
