Gantry axes
Only one of the clearance-controlled axes may be configured as the master axis of a gantry
grouping, defined via machine data:
MD37100 $MA_GANTRY_AXIS_TYPE (gantry axis definition)
Following axes in a gantry grouping may not be used in the context of clearance control.
Displaying the axis position
The actual current axis position of a clearance-controlled axis as the sum of an interpolatory
axis position and the current position offset of clearance control is not displayed in the main
machine screen on a SINUMERIK standard HMI:
•
SINUMERIK HMI Advanced
•
SINUMERIK HMI Embedded
With the HMIs mentioned, the actual current axle position is displayed on the service screen
Operating area switchover > Diagnosis > Service Displays > Axle/ Spindle as the "actual
position value".
NC channels
The "clearance control" technological function is only available in the first NC channel, even
on controls with more than one NC channel.
•
Only channel axes in the first NC channel may be used as clearance-controlled axes.
•
CLC part program commands may only be used in part programs processed in the first NC
channel.
Conflict with other machine data
Using the following machine data is not permitted:
MD30132 $MA_IS_VIRTUAL_AX = 1 (axis is virtual axis)
Note
The "clearance control" technological function is only available in the first NC channel!
