The channels not selected here are brought into the "Program test (PRT)"state. As a consequence, the channels are only calculated, but are not processed.No M and auxiliary functions or tool functions are output. Spindle commands are only outputfor selected spindles.Running-in spindle-by-spindleOnly machining operations are executed for the spindle selected under program control /running-in. When programming, using the block formation, allocate the correspondingmachining operations to a spindle.When generating a block, a complete block can be assigned to a spindle. For the case thatthe block is not executed, as the specified spindle should not be considered when running in,then it is possible to temporarily activate what is known as an "Addit. run-in code".Software optionsYou require the "programSYNC" option for cross-channel program control.Precondition● Multi-channel machine● You have selected the multi-channel view via "Settings for channel functionalities".Multi-channel machining11.2 Multi-channel supportTurning634 Operating Manual, 05/2017, A5E40868721
