Technology G group
Five dynamic response settings are available in G code group 59 technology:
• DYNORM for standard dynamic response
• DYNPOS for positioning mode, tapping
• DYNROUGH for roughing
• DYNSEMIFIN for finishing
• DYNFINISH for smooth-finishing
For further information about programming, see:
Reference:
/PG/ Programming Manual Fundamentals, path traversing behavior.
Enabling selected dynamics groups only
Some G codes can be deactivated by the machine manufacturer. If deactivated G codes are
programmed alarm 14011 is output. G codes DYNPOS for positioning mode and
DYNSEMIFIN for finishing, for example, can be deactivated with the following setting.
MD10712 $MN_NC_USER_CODE_CONF_NAME_TAB[0]="DYNPOS" (list of reconfigured
NC codes)
MD10712 $MN_NC_USER_CODE_CONF_NAME_TAB[1]=" "
MD10712 $MN_NC_USER_CODE_CONF_NAME_TAB[2]="DYNSEMIFIN"
MD10712 $MN_ NC_USER_CODE_CONF_NAME_TAB[3]=" "
Configuring the dynamic response values.
The values for each technology group are stored in the following machine data:
• Axis
MD32300 $MA_ MAX_AX_ACCEL[n] (axis acceleration)
MD32431 $MA_MAX_AX_JERK[n] (maximum axial jerk for path motion)
MD20600 $MA_MAX_PATH_JERK[n] (path-related maximum jerk)
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)
• path
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 frange for index n = 0 to 4
