6.7 Axis-specific MD 2 (axial data 2)
Application:
A gearbox grouping can be configured with the G401 command. If the type of link has not
been defined in the G401 command, the default value from MD 1456* is taken.
Example:
G401 X Y Z X, Y: leading axes, Z: following axis, no link type.
If "No default" (MD 1456* = 0) has been entered and no link type has been entered in G401,
reset alarm "GI CONFIGURATION illegal" is triggered.
