Detailed Description
2.3 Continuous-path mode
The dynamic response for these axis movements is still derived from the machine data of the
DYNNORM default setting.
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, please refer to

/PG/, Programming Guide 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: NC_USER_CODE_CONF_NAME_TAB[0]="DYNPOS"
MD10712: NC_USER_CODE_CONF_NAME_TAB[1]=" "
MD10712: NC_USER_CODE_CONF_NAME_TAB[2]="DYNSEMIFIN"
MD10712: NC_USER_CODE_CONF_NAME_TAB[3]=" "
