Synchronized Axes - Siemens SINUMERIK 828D Function Manual

Application
Certain axes in the main run can be decoupled at the channel response triggered by the NC program sequence
and controlled from the PLC. These axes are also interpolated in the main run and respond independently for the
channel and program sequence.
A PLC-controlled axis can then be controlled independently by the NC. This concerns the following actions:
• The sequence for canceling the axis (equivalent to delete distance­to­go)
• Stopping or interrupting the axis
• Continuing the axis (continue sequence of motion)
• Resetting the axis to its basic status

Synchronized axes

Significance
Synchronous axes are components of the path axes, which are not referenced in order to calculate the tool path
velocity. They are interpolated together with path axes (all path axes and synchronous axes of one channel have
a common path interpolator).
All path axes and all synchronous axes of a channel have the same acceleration phase, constant travel phase
and deceleration phase.
The feedrate (path feedrate) programmed under address F applies to all the path axes programmed in a block
but not to the synchronous axes.
Synchronous axes take the same time to cover the programmed path as the path axes.
