In addition to configuring the particular MD, handwheel direction of rotation inversion can be
activated by setting the IS "Invert the handwheel direction of rotation" belonging to the particular
axis:
● Machine axes:
– DB31, ... DBX7.0 (invert handwheel direction of rotation)
● Geometry axes:
– DB21, ... DBX15.0 (geometry axis 1: Invert handwheel direction of rotation)
– DB21, ... DBX19.0 (geometry axis 2: Invert handwheel direction of rotation)
– DB21, ... DBX23.0 (geometry axis 3: Invert handwheel direction of rotation)
● Orientation axes:
– DB21, ... DBX323.0 (orientation axis 1: Invert handwheel direction of rotation)
– DB21, ... DBX327.0 (orientation axis 2: Invert handwheel direction of rotation)
– DB21, ... DBX331.0 (orientation axis 3: Invert handwheel direction of rotation)
● Contour handwheel:
– DB21, ... DBX31.5 (invert contour handwheel direction of rotation)
Note
The inversion signal should be set in the PLC user program at the same time as the handwheel
selection (IS "Activate handwheel").
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 direction of rotation inversion active)
