5.6 SE timing diagrams
This section shows several process examples and the relevant PLC signals in chronological sequence.
As Rexroth tightening systems are used in a wide variety of control environments, it cannot be guaranteed
that the PLC signals are always available at defined times, e.g. CyCmp. Delays may be influenced e.g. by
data outputs and their settings at the interfaces.
PLC signal status is described as follows:
PLC signal conditions on referencing of the open position (page 133) and in the tightening process with
opening the flat output drive (page 192) are described as follows:
