4.4 Time sequence diagrams
4.4.1 Example for time sequence diagram of the signal "Start cycle CW"
The same is also valid for the signal "Start cycle CCW".
Fig. 16: Example for time sequence diagram of the signal "Start cycle CW"
a) If the feedback "Ready for switching on" is HIGH, the rotary indexing table can be released by the control signal
"Enable".
If the rotary indexing table is enabled, this is signalled by the "Enable active" feedback.
b) The "Stop (low active)" signal can also be sent before the "Enable" signal.
The "Stop selected" feedback switches to LOW. The "Ready to start" feedback switches to HIGH as soon
as the rotary indexing table is released and "Stop (low active) is HIGH.
c) If the feedback "Ready to start" is HIGH, the rotary indexing table can be cycled by the control signal "Start cycle
CW".
The "Start cycle CW" control signal has to be set only for one EF2 control cycle and can then be taken
back immediately. Runtime tolerances during the signal transmission need to be taken into account.
d) At this time, the external processing can be started.
The cycle is not completed yet at this time.
e) The next cycle can be started at this point.
