Synchronized Axes - Siemens SINUMERIK 840D sl Function Manual

This interpolation can be started as follows:
● From synchronized actions
(as command axes due to an event via block-related, modal or static synchronized actions)
● From the PLC via special function blocks in the basic PLC program
(named as a concurrent positioning axis or a PLC axis)
● Via the setting data or from the part program
(as an asynchronous or block-synchronous oscillating axis)
Channel control
An axis interpolated by the main axis reacts in terms of:
● NC stop
● Alarm handling
● Program control
● End of program
● RESET
Note
The response at the end of the program varies. The axis movement need not always be
completed and, therefore, may carry on beyond the end of the program.
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

Meaning
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).
