4.2.1
Acceleration and jerk for positioning motion to fixed points
4.2.1.1
General Information
For acceleration, and jerk, for traversing to fixed point positions, specific values can be parameterized using
G75
/
G751
. These are then effective for all types of positioning motion.
4.2.1.2
Parameterization
The values for acceleration and jerk of an axis are parameterized on an axis and parameter set basis in the
following machine data:
MD32300 $MA_MAX_AX_ACCEL[0 … n] (acceleration, n = parameter set index)
MD32431 $MA_MAX_AX_JERK[0 … n] (jerk, n = parameter set index)
For positioning motion to fixed point positions (G75 / G751), the following values are used for acceleration and
jerk dependent on the activation of the function:
• Not active function: Parameter set 1 (index 0)
• Active function: Parameter set 2 (index 1)
Activation is carried out via the NC-specific machine data:
MD18960 $MN_POS_DYN_MODE = <mode>
<mode> Meaning
