3-18 Relative Scaling Reference Resource
Option: Function:
Select a variable value to be added to the fixed value (defined in par. 3-14
Preset Relative Refer-
ence
). 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.
This parameter cannot be adjusted while the motor is running.

3.5.4 Ramps
3-4* Ramp 1
For each of four ramps (par. 3-4*, par. 3-5*, par. 3-6* and par. 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.
