Cross-mode synchronized actions
Modal synchronized actions can be executed per IDS in all modes for the following functions
in parallel to the channel:
• Command axis functions
• Spindle functions
• Technology cycles
Selection
The user can select the desired operating mode by means of soft keys on the operator
interface.
This selection (AUTOMATIC, MDA, or JOG) is forwarded to interface signals:
DB11, ... DBX4.0 to DBX4.2 (mode strobe)
in the PLC, but is not activated at this point.
Activation and priorities
The required operating mode of the mode group is activated via interface signals:
DB11, ... DBX0.0 to DBX0.2 (operating mode).
If several modes are selected at the same time the priority is as follows:
• JOG (1st priority, high) (DB11, ... DBX0.2)
• MDA (2nd priority, medium) (DB11, ... DBX0.1)
• AUTOMATIC (3rd priority, low) (DB11, ... DBX0.0)
