Activation/Deactivation
Continuous-path mode with rounding based on a path criterion can be activated in any NC part program block by
the modal command G641. Before or on selection, the path criteria ADIS/ADISPOS must be specified.
Selecting the exact stop which works on a block-by-block basis enables rounding to be interrupted (G9).
Continuous-path mode with rounding based on a path criterion (G641) can be deactivated by selecting:
• Modal exact stop (G60)
• Continuous-path mode G64, G641, G642, G644 or G645
