Activation of the function

The screen form for CYCLE996 ("Measure kinematics") is activated via the global GUD6
variable _MZ_MASK[8] = 1
as follows:

Measuring kinematics

Starting from the kinematics initial state, the relevant rotary axes are measured individually.
Process
● Rotary axes 1 or 2 can be measured in any order. If the machine kinematics only have
● The basic data for the kinematics are always the data of the tool carrier with orientation
● The linear and rotary axes must be prepositioned on the starting positions P1 to P3 (see
● In each of the ball (rotary axis) positions selected, measuring is performed in accordance
● The kinematics are calculated via a separate, parameterized call of CYCLE996.
● The measuring results are written to the result parameter (OVR parameter) after the 3rd
● A protocol file with the measurement results in an appropriate data format (machine data
