3-18 Relative Scaling Reference Resource
Option: Function:
Select a variable value to be added to the
fixed value (defined in
3-14 Preset Relative
Reference ). The sum of the fixed and variable
values (labelled Y in the illustration below) is
multiplied with the actual reference (labelled
X in the illustration below). This product is
then added to the actual reference (X+X*Y/
100) to give the resultant actual reference.

, which is a fixed output
speed. The frequency converter
runs at this speed when the jog

3.5.3 Ramps
3-4* Ramp 1
For each of four ramps (parameter groups 3-4*, 3-5*, 3-6*
and 3-7*) configure the ramp parameters: ramp type,
ramping times (duration of acceleration and deceleration)
and level of jerk compensation for S ramps.
Start by setting the linear ramping times corresponding to
the figures.

If S-ramps are selected then set the level of non-linear jerk
compensation required. Set jerk compensation by defining
the proportion of ramp-up and ramp-down times where
acceleration and deceleration are variable (i.e. increasing or
decreasing). The S-ramp acceleration and deceleration
settings are defined as a percentage of the actual ramp time.
