Function
Even in their basic configuration, SINUMERIK CNCs allow up to 24 actions to be initiated in synchronism with axis and spindle movements. These actions run in parallel with workpiece machining; specific conditions are used to define when they become active. The starting of such motion-synchronized actions – or synchronized actions for short) is, therefore, not restricted to CNC block boundaries. Synchronized actions are an excellent programming tool for supporting very quick responses to events in the interpolation cycle.
Synchronized actions are executed in the interpolation cycle. Multiple actions can be processed in the same IPO cycle. Synchronized actions without validity identifier are active non-modally only in the automatic mode. In the automatic mode, synchronized actions with validity identifier ID are modal in the subsequently programmed blocks.
Statically effective synchronized actions with the identifier IDS remain active in all CNC operating modes: cross-mode actions.
Possible actions in synchronized actions are e.g.:
- Output of auxiliary functions to PLC
- Writing and reading of main run variables
- Positioning of axes/spindles
- Activation of synchronous procedures such as: read-in disable, delete distance-to-go, end preprocessing stop
- Activation of technology cycles
- Online calculation of function values
- Online tool offsets
- Activation/deactivation of couplings/coupled motion
- Take measurements
- Enabling/disabling of synchronized actions
