Current angular offset
The current angular offset of a following spindle in relation to the leading spindle can be read
using the following system variable:
●
$AA_COUP_OFFS[<FS>] (angular offset on the setpoint side)
●
$VA_COUP_OFFS[<FS>] (angular offset on the actual value side)
Note
When the controller has been disabled and subsequently re-enabled during active
coupling and follow-up mode, the position offset when the controller is re-enabled is
different to the original programmed value. In this case, the new position offset can be
read and, if necessary, corrected in the part program.
