Meaning
JERKLIM: Adapting the jerk limit value
<Ax>: Machine axis whose jerk limit value is to be adapted
<Value>: Percentage correction value
The correction value refers to the configured maximum axis jerk for path motion
(MD32431 $MA_MAX_AX_JERK).
Value range: 1 ... 200
Value 100 does not influence the jerk.
Note
Response at the end of the part program and for a channel reset
The response of JERKLIM at the end of the part program and for a channel reset depends on
the setting of bit 0 in machine data MD32320 $MA_DYN_LIMIT_RESET_MASK:

Program code Comment
N1000 G0 X0 Y0 F10000 SOFT G64
N1100 G1 X20 RNDM=5 ACC[X]=20 ACC[Y]=30
N1200 G1 Y20 JERKLIM[Y]=200 ; The axis slide in the Y direction can be
accelerated/decelerated with max. 200% of
the jerk permissible for the axis.
N1300 G1 X0 JERKLIM[X]=2 ; The axis slide in the X direction
should only be accelerated/decelerated
with max. 2% of the jerk permissible for
the axis.

3.14.9.2 Adapting the maximum axis velocity or spindle speed (VELOLIM)
In the part program, the maximum possible velocity of an axis or the maximum possible gear-
stage-dependent speed of a spindle set via machine data can be reduced using the VELOLIM
command.
Effectiveness
VELOLIM acts:
● In the AUTOMATIC operating modes
● On path and positioning axes.
● On spindles in spindle/axis operations
