4.4.2 Example for time sequence diagram of the signal "Start level CW"
The same is also valid for the signal "Start level CCW".
Fig. 17: Example for time sequence diagram of the signal "Start level 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 level
CW".
The control signal needs to be set for the total time of the cycle, otherwise the current cycle is interrupted.
d) At this time, the external processing can be started.
The cycle is not completed yet at this time.
e) At this point, the control signal "Start level CW" can be reset.
f)
The next cycle can be started at this point.
As soon as the control signal is reset after the end of a cycle, the "Ready to start" feedback switches back
to HIGH.
