3-17 Reference Resource 3
Option: Function:
Select the reference input to be used
for the third reference signal.
3-15 Reference Resource 1,
3-16 Reference Resource 2 and
3-17 Reference Resource 3 define up to
three different reference signals. The
sum of these reference signals
defines the actual reference.

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 (labeled Y in the figure below) is
multiplied by the actual reference (labeled X
in the figure below). The result is then added
to the actual reference (X+X*Y/100) to give
the resulting actual reference.
This parameter cannot be adjusted while the
motor is running.

Enter a value for the jog speed
n
JOG
, which is a fixed output
speed. The adjustable frequency
drive runs at this speed when the
jog function is activated. The
maximum limit is defined in
4-13 Motor Speed High Limit
[RPM].

3.5.3 Ramps
3-4* Ramp 1
For each of four ramps (par. group 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.
