clamping monitoring functions:
2.1.2.2 Positioning monitoring
Function
At the end of a positioning operation:
• Set velocity = 0 AND
• DB31, ... DBX64.6/64.7 (motion command minus/plus) = 0
checks the position monitoring to ensure that the following error of every participating
machine axis is smaller than the exact-stop fine tolerance during the delay time.
MD36010 $MA_STOP_LIMIT_FINE (exact stop fine)
10
Basic logic functions: Axis monitoring, protection zones (A3)
