Brief Description
1
1.1 Axis monitoring functions
Function
Comprehensive monitoring functions are present in the control for protection of people and
machines:
• Contour monitoring
• Position monitoring
• Zero-speed monitoring
• Clamping monitoring
• Speed-setpoint monitoring
• Actual-velocity monitoring
• Measuring System- Monitoring
• Limit switches-monitoring
• Monitoring of the working area limitation
1.2 Protection zones
Function
With the help of protection zones, elements of the machine (e.g. spindle chuck, tool changer,
tool holder, tailstock, movable probe, etc.) and the workpiece can be protected against
collisions.
During automatic execution of part programs in the AUTOMATIC or MDI mode, the NC
checks at the start of every part-program block whether a collision between protection zones
can occur upon moving along the programmed path.
After manual deactivation of an active protection zone, the zone can be entered. After
leaving the protection zone, the protection zone automatically becomes active again.
The definition, activation and deactivation of protection zones takes place via part program
instructions.
