Dynamic response mode for path interpolation

Function
Technology-specific, dynamic response settings can be saved in machine data and can be
activated in the part program via the commands from G function group 59 (dynamic response
mode for path interpolation).
Command
DYNNORM
DYNPOS
DYNROUGH
DYNSEMIFIN
DYNFINISH
Note
The dynamic response of the path axes alone is determined by the commands from G function
group 59 (dynamic response mode for path interpolation). They have no effect on:
● Positioning axes
● PLC axes
● Command axes
● Motions based on axis coupling
● Overlaid motions with handwheel
● JOG motions
● Reference point approach (G74)
● Fixed-point approach (G75)
● Rapid traverse motion (G0)
The standard dynamic response setting (DYNNORM) always takes effect for these axis
motions.
Application
By switching the dynamic response settings, roughing can be optimized in terms of time and
smoothing can be optimized in terms of the surface, for example.
Parameterization
Axis-specific dynamic response settings:
● MD32300 $MA_MAX_AX_ACCEL[<n>] (axis acceleration)
● MD32310 $MA_MAX_ACCEL_OVL_FACTOR[<n>] (overload factor for axial jumps in
velocity)
● MD32431 $MA_MAX_AX_JERK[<n>] (maximum axial jerk for path motion)
