Offset after point of activation
New offset after point of activation.
This bit is set to 1 if a particular event (SW/HW limit switch on CC_Slave axis) causes a change
in the offset between CC_Master and CC_Slave stored when the coupling was activated.
No new offset since activation.
The bit is not set in the RESET phase.
Displayed only for the CC_Slave axis.
Reverse/Forward
Signal(s) updated:
Activate reverse travel.
The RESU main program CC_RESU.MPF is generated from the traversing blocks recorded in the
RESU-internal block buffer in order to initiate travel back along the contour on the next NC START.
Activate forward travel.
The RESU main program CC_RESU.MPF is generated from the traversing blocks recorded in the
RESU-internal block buffer in order to initiate travel forwards along the contour on the next NC
START.
Not relevant.
Start retrace support
Signal(s) updated:
Start retrace support:
The original machining program is reselected and a block search is carried out to locate the
program continuation point.
Not relevant.
