Procedure with MVAR=00x105: Intermediate positioning at an angle
Position before measuring cycle call
The probe is positioned with respect to the surface to be measured in such a way that during
traversal of the measuring axis _MA specified in the direction of the setpoint
_SETVALmeasuring point 1 on the surface will be reached.
Recommended distance from _SETVAL: >_FA.
The measuring operation then starts with the measuring feed at distance _FA in front of
_SETVAL.
The absolute value of the positional deviation from the setpoint must not be greater than the
measuring path _FA. Otherwise, no measurement will be performed.
In the other two axes, the positions are retained for the measurement in measuring point 1 at
the beginning of a cycle.
Intermediate positioning at an angle
The starting point for measurement 2 is approached at an angle. The angle comprises
_STA1 and _TSA. _TSA contains the value for a permissible angle deviation and leads away
from the setpoint.
