The acknowledgement that the handwheel direction of rotation has been inverted by the NC is
realized for each axis using the IS "Handwheel direction of rotation inversion active":
● Machine axes:
– DB31, ... DBX67.0 (handwheel direction of rotation inversion active)
● Geometry axes:
– DB21, ... DBX43.0 (geometry axis 1: Handwheel direction of rotation inversion active)
– DB21, ... DBX49.0 (geometry axis 2: Handwheel direction of rotation inversion active)
– DB21, ... DBX55.0 (geometry axis 3: Handwheel direction of rotation inversion active)
● Orientation axes:
– DB21, ... DBX335.0 (orientation axis 1: Handwheel direction of rotation inversion active)
– DB21, ... DBX339.0 (orientation axis 2: Handwheel direction of rotation inversion active)
– DB21, ... DBX343.0 (orientation axis 3: Handwheel direction of rotation inversion active)
● Contour handwheel:
– DB21, ... DBX39.5 (contour handwheel: Handwheel direction of rotation inversion
Note
It is only permissible to change the inversion signal at standstill. If the change is made while
motion setpoints are being output by the interpolator, then the signal change is rejected and an
alarm is output; further, motion is stopped taking into account the actual acceleration value.
Abort/interruption of the traversing motion
The following NC/PLC interface signals abort the traversing motion. The setpoint/actual-value
difference is deleted.
NC/PLC interface signal
DB21, ... DBX7.7 (NC reset)
DB21, ... DBX12.0 - 2 (geometry axis 1: Activate hand‐
wheel)
DB21, ... DBX16.0 - 2 (geometry axis 2: Activate hand‐
wheel)
DB21, ... DBX20.0 - 2 (geometry axis 3: Activate hand‐
wheel)
DB21, ... DBX6.2 (delete distance-to-go)
DB31, ... DBX2.2 (delete distance-to-go / spindle reset) Geometry axis / machine axis
DB31, ... DBX4.2 (activate handwheel)
DB31, ... DBX1.3 (axis/spindle disable)
DB31, ... DBX1.5 (position measuring system 1)
DB31, ... DBX1.6 (position measuring system 2)
