Constraints
Continuous-path mode
For the above-mentioned functions:
• Automatic stopping for removal of the clamp
• Optimized releasing of the axis clamp via travel command
• Automatic stopping for setting of the clamp
the "Look Ahead" function must be active.
Part-program blocks without path motion (e.g., M82/M83) interrupt continuouspath mode and
thus also the "Look Ahead" function.
Example:
The part-program blocks N320 and N420 are inserted in the programming example used.
