Supplementary conditions:
● The analog voltage of the clearance sensor is connected via the analog input $A_INA[3].
● The position deviations are summed up in $AA_OFF (integrated):
● If the upper limit of the Z axis is exceeded by 1 mm, the X axis is stopped:

MD36750 $MA_AA_OFF_MODE, bit 0 = 1
SD43350 $SA_AA_OFF_LIMIT[Z] = 1
See also Section "Overlaid movements ($AA_OFF) (Page 45)".
Note
$AA_OFF is effective in the basic coordinate system (BCS)
The offset is effective before the kinematic transformation in the basic coordinate system
(BCS). The example therefore cannot be used for a clearance control in the orientation
direction of the tool (workpiece coordinate system WCS).
For clearance control system with high dynamic response or 3D clearance control, see:

Customized responses
When the limit value SD43350 $SA_AA_OFF_LIMIT is reached, customized responses
can be triggered, for example:
• Section "Override ($A...OVR) (Page 34)"
• Section "User-specific error reactions (SETAL) (Page 118)"
