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.
3-19 Jog Speed [RPM]
Range:
0 - par. 4-13 RPM
Function:
Enter a value for the jog speed n
fixed output speed. The adjustable frequency
drive runs at this speed when the jog function
is activated. The maximum limit is defined in
par. 4-13 Motor Speed High Limit (Hz).

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 of
acceleration and deceleration) and level of
jerk compensation for S ramps.
Start by setting the linear ramping times
corresponding to the figures and formulas.

How to Program
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
150 RPM
and deceleration are variable (i.e., increasing
or decreasing). The S-ramp acceleration and
, which is a
deceleration settings are defined as a percentage

of the actual ramp time.
*
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
