In particular, the specific features of the following functions are taken into account:● Tapping with compensating chuck and speed-controlled spindle with encoder (G33)● Tapping without compensating chuck and position-controlled spindle (G331, G332)● Machining with tool orientation with swivel cycle CYCLE800 or orientation transformationAvailabilityJOG retract can only be selected if one of the following functions was interrupted as a resultof a channel reset or power off:● Tapping using G33/G331/G332● Machining using tool type 2xx (drilling tools)Data to be restoredIn order to be able to execute the retraction in the tool direction after a program abort, thefollowing data which was active in the channel before the program abort, is restored:● Active tool offset● Active machining plane● Active tool carrier● Active transformation data block with transformation parameters● Data of the thread group with G33 or G331/G332● Positions of the axes that are involved in the transformationIf this data is completely available after a program abort, it is restored in the channel when theJOG retract machine function is selected. In this case, the workpiece coordinate system (WCS)is aligned by the control in such a way that one of the geometry axes is in the direction of thetool axis. The tool retraction can then be performed manually by traversing this geometry axis.NoteData backupThe specified data itself is not backed up, only the references to this data. If the data is changedprior to the selection of JOG retract, the function is performed on the basis of the changed data.RestrictionsPrograms that can be started by interrupt signals are not executed in JOG retract.H1: Manual and handwheel travel4.12 Retraction in the tool direction (JOG retract)Extended Functions208 Function Manual, 10/2015, 6FC5397-1BP40-5BA3
