Percentage jerk correction (JERKLIM)

Function
In critical program sections, it may be necessary to limit the jerk to below the maximum
possible value - e.g. to reduce the level of stress on the machine. The acceleration mode
SOFT must be active. The function only effects path axes.
Syntax
JERKLIM[<axis>]=<value>
Significance
JERKLIM
<axis>
<value>
Example
In the AUTOMATIC operating modes, for the programmed axis, the jerk limit value is limited
to the specified percentage of the jerk limit value saved in the machine data:
N60 JERKLIM[X]=75
Meaning: The axis slide in the X direction should only be accelerated/decelerated with 75%
of the jerk permissible for the axis.

Command for jerk correction
Machine axis whose jerk limit value is to be adapted.
Change as a percentage for the highest permissible jerk referred to the
value set for the axis in the machine data.
Range of values: 1 ... 200
Value 100 does not influence the jerk. This setting is effective after a
reset and part program start.
