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.
