This product is then added to the actual reference
(X+X*Y/100) to give the resulta nt actual reference.
This parameter cannot be adjusted while
the motor is running.

" Ramps
3-4* Ramp 1
For each of four ramps (par. 3-4*, 3-5*, 3-6*
and 3-7*), configure the ramp parameters:
ramp type, ramping times (duration o f
acceleration and deceleration) and level of
jerk compensation for S ramps.
Start by se tting the linear ramping t imes
corresponding to the figures and formulas.
If S -ramps are selected, then set t he 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). T he S-ramp acceleration and
deceleration settings are defined as a pe rcentage
of the actual ramp time.
3-40 Ramp 1 Type
Option:

Linear [0]
S-ramp [1]
Function:
Selects the desired ramp type, depending on
requirements for
acceleration/deceleration.
A linear ramp will give constant acceleration
during ramping. An S-ramp will give
