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