signals
If no reference cam exists, the axis directly moves to the zero mark (in the defined start direction). Without a reference cam, the tolerance bandwidth is not evaluated.
When "flying referencing" is selected (passive referencing, p2597 = 1 signal), this function diagram is of no significance => refer to [3614].
The connector outputs are only supplied with values from here if the “referencing“ mode is active.
The reversing cams are low active. When a cam is actuated, motion (reference cam search) is continued in the opposite direction.
Reference point setting is only effective in the initial state [3625].
