Percentage jerk correction (JERKLIM)

Function
In critical program sections, it may be necessary to limit the jerk to below maximum value, for
example, to reduce mechanical stress. The acceleration mode SOFT must be active. The
function only effects path axes.
Programming
JERKLIM[axis]= ...
Parameters
JERKLIM
Axis
Value range: 1 ... 200
Example
In the AUTOMATIC modes, the jerk limit is limited to the percentage of the jerk limit stored in
the machine data.
N60 JERKLIM[X]=75
Meaning: The axis carriage in the X direction must be accelerated/decelerated with only 75%
of the jerk permissible for the axis.
Note
Another example in provided in the section "Percentage velocity correction (VELOLIM)".

13.12 Influencing the motion control
Percentage change for the greatest permissible jerk
relative to the value set in the machine data for
the axis.
Machine axis whose jerk limit has to adapted.
100 corresponds to: no effect on the jerks.
100 is applied after RESET and parts program start.
