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 controlAn axis interpolated by the main axis reacts in terms of:● NC stop● Alarm handling● Program control● End of program● RESETNoteThe response at the end of the program varies. The axis movement need not always becompleted and, therefore, may carry on beyond the end of the program.ApplicationCertain axes in the main run can be decoupled at the channel response triggered by the NCprogram sequence and controlled from the PLC. These axes are also interpolated in the mainrun and respond independently for the channel and program sequence.A PLC-controlled axis can then be controlled independently by the NC. This concerns thefollowing 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 status10.2.9 Synchronized axesMeaningSynchronous axes are components of the path axes, which are not referenced in order tocalculate the tool path velocity. They are interpolated together with path axes (all path axesand synchronous axes of one channel have a common path interpolator).K2: Axis Types, Coordinate Systems, Frames10.2 AxesBasic FunctionsFunction Manual, 01/2015, 6FC5397-0BP40-5BA2 673
