Effectiveness
The function is effective:
● In the AUTOMATIC operating modes.
● Only on path axes.
Syntax
JERKLIM[<axis>]=<value>
Meaning
JERKLIM
<axis>
<value>
Note
The behavior of JERKLIM at the end of the part program and channel reset is configured
with bit 0 in machine data MD32320 $MA_DYN_LIMIT_RESET_MASK:
 Bit 0 = 0:
 Bit 0 = 1:
Example
Program code
...
N60 JERKLIM[X]=75

: Command for jerk correction
: Machine axis whose jerk limit value is to be adapted.
: Percentage correction value, referred to the configured maximum axis jerk
for path motion (MD32431 $MA_MAX_AX_JERK).
Range of values: 1 ... 200
Value 100 does not influence the jerk.
The programmed value for JERKLIM is reset to 100% with channel reset/M30.
The programmed value for JERKLIM is retained beyond the channel reset/M30.
Comment
; The axis slide in the X direction should only be
accelerated/decelerated with a maximum of 75% of the
jerk permissible for the axis.
