Monitoring
If a machine axis is in follow-up mode, the following monitoring mechanisms will not act:
• Zero-speed monitoring
• Clamping monitoring
• Positioning monitoring
Effects on other interface signals:
• DB31, ... DBX60.7 = 0 (position reached with exact stop fine)
• DB31, ... DBX60.6 = 0 (position reached with exact stop coarse)
DB31, ... DBX1.5 / 1.6 (position measuring system 1 / 2)
2 measuring systems can be connected to one machine axis, e.g.,
• Indirect motor measuring system
• Direct measuring system on load
Only one measuring system can be active at any one time. All closed-loop control,
positioning operations, etc. involving the machine axis always relate to the active measuring
system.
