Tightening
334 9836 3521 01
This check requires that the start condition and, if specified, the stop condition are met. In
addition, the angle measured between these two points must be larger than the angle
corresponding to one (1) encoder increment. If not, and at least one limit is specified, the
steps status is set to Fatal and the error bit of the respective limit is set.
The paramters Falling Edge , Type are only available for Gauging. In Tightening rising
edge and type „Two point‟ is always used.
