Example 9 - Process connection

This example applies both known event generator blocks EG_w/s/f - see example 8 - process connection - and extended event generator blocks EGE_w/s/f. Latter offer a static event signal at output 2. Input 2 resets this output. As can be seen from the figure above any logical connections may be realized with this.

ES_34	drive 3 reached a reference angle	ES_10	ES_8 and no STOP signal
ES_5	drives 1 and 2 reached production speed	ES_11	ES_8 and STOP signal
ES_6	drive 3 reached angle 1 (welding start)	ES_12	drives 1 and 2 reached zero speed
ES_7	ES_5 and ES_6 synchronous	ES_13	see ES_34
ES_8	drive 3 reached angle 2 (welding stop)	ES_14	drive 3 reached zero speed
ES_9	see ES_6
