Programming sequence:
 Position the cursor in the MACHINING program section
 Program G726 with H=1 (activate coupling)
 Program turning cycles
 Program G726 with H=0 (deactivate coupling)
Please note while programming:
 Program a workpiece blank increased by the center
offset in the radius if you are using turning cycles that
are referenced to the workpiece-blank definition.
 Program a starting point increased by the center offset
in the radius if you are using turning cycles that are not
referenced to the workpiece-blank definition.
 Reduce the spindle speed if you increase the center
offset.
 Reduce the maximum rapid traverse F if you increase
the center offset.
 Use identical values for the parameter Q when activating
and deactivating the coupling.
Please note when executing the program:
 When the coupling is activated, the control positions the
tool in the Z axis to the value of the parameter Z.
 In the event of a program cancelation, the control
automatically deactivates the coupling.
