3.4 Dynamic adaptations
Basic Functions
192 Function Manual, 09/2011, 6FC5397-0BP40-2BA0
Application
By switching the dynamic response settings, roughing a workpiece can be optimized in terms of time and
smoothing it can be optimized in terms of the surface, for example.
Parameter assignment
Parameters are assigned to the specific dynamic response settings:
• For the axis in question via the machine data:
- MD32300 $MA_ MAX_AX_ACCEL[<n>] (axis acceleration)
- MD32431 $MA_MAX_AX_JERK[<n>] (maximum axial jerk for path motion)
- MD32432 $MA_PATH_TRANS_JERK_LIM[<n>] (max. axial jerk at the block transition in continuous-path
mode)
- MD32310 $MA_MAX_ACCEL_OVL_FACTOR[<n>] (overload factor for axial jumps in velocity)
- MD32433 $MA_SOFT_ACCEL_FACTOR[<n>] (scaling of the acceleration limitation with SOFT)
• For the axis via the machine data:
- MD20600 $MA_MAX_PATH_JERK[<n>] (path-related maximum jerk)
- MD20602 $MC_CURV_EFFECT_ON_PATH_ACCEL[<n>] (influence of path curvature on dynamic path
response)
- MD20603 $MC_CURV_EFFECT_ON_PATH_JERK[<n>] (influence of path curvature on path jerk)
Value range for index n:
Index <n> Meaning
0 Value for DYNNORM
1 Value for DYNPOS
2 Value for DYNROUGH
3 Value for DYNSEMIFIN
4 Value for DYNFINISH
NOTICE
Writing the machine data without an index places the same value in all field elements of the
machine data in question.
Reading the machine data without an index always supplies the value of the field with index
0.
