Detailed description
2.5 Generic coupling
Stop of a following axis/spindle.
An active overlaid motion is also
braked to standstill. Then the coupling
is opened, (deactivated).
For spindles and main traverse axes
only!
The following spindle continues to
traverse at the speed/velocity that
applied at the instant of deactivation.
