Positioning axes have their own axis-specific feedrate override value. This feedrate override
is evaluated in the same way as the channel-specific feedrate override.

The axis-specific distance-to-go of the positioning axis is canceled. The positioning axis is
decelerated and the following error is eliminated. The programmed end position is deemed to
have been reached. The path axes are not influenced by the axis-specific "delete distance-to-
go" interface signal. The channel-specific "delete distance-to-go" interface signal is used for
this purpose.

If the axis-specific "delete distance-to-go" interface signal is enabled, even if no positioning
axes have been programmed in this block, the NCK does not respond.
