Service display for FS
In the "Diagnostics" operating area, when commissioning in the synchronous mode, the
following values are displayed for the following spindle:
● Actual deviation between setpoints of FS and LS
Value displayed: Position offset in relation to leading spindle (setpoint)
(value corresponds to angular offset between FS and LS that can be read with axis variable
$AA_COUP_OFFS in the part program)
● Actual deviation between actual values of FS and LS
Value displayed: Position offset in relation to leading spindle (actual value)
