● MD32432 $MA_PATH_TRANS_JERK_LIM[<n>] (maximum axial jerk at the block transition
in continuous-path mode)
● MD32433 $MA_SOFT_ACCEL_FACTOR[<n>] (scaling of the acceleration limitation with
SOFT)
Channel-specific dynamic response settings:
● MD20600 $MC_MAX_PATH_JERK[<n>] (path-related maximum jerk)
● MD20602 $MC_CURV_EFFECT_ON_PATH_ACCEL[<n>] (influence of path curvature on
path acceleration)
● MD20603 $MC_CURV_EFFECT_ON_PATH_JERK[<n>] (influence of path curvature on
path jerk)
where index <n> =0
Note
Writing the machine data without an index places the same value in all field elements of the
relevant machine data.
Reading the machine data without an index always supplies the value of the field with index
0.
Suppressing G commands
It is recommended that G commands from G function group 59 (dynamic response mode for
path interpolation) which are not intended for use should be suppressed via the following
machine data:
MD10712 $MN_NC_USER_CODE_CONF_NAME_TAB[<n>] (list of reconfigured NC
commands)
If a suppressed G command is used, an alarm is displayed. This prevents machine data that
has not been parameterized taking effect.
Example
The G commands DYNPOS and DYNSEMIFIN can be suppressed with the following settings:
● MD10712 $MN_NC_USER_CODE_CONF_NAME_TAB[0]="DYNPOS"
● 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]=" "
