The setting of t1 and t2 is wrong. If the timing is wrong the PM cannot execute the signal, which is necessary to memorize the canbodies in the reject unit and to start the record of the graph.
Setting of t1 and t2:
t1 defines the starting point for the reduced current time window.
t2 is the time, where the reduced current windows ends. t2–t1= thus is the timespan for the reduced current, therefore t2 > t1!
The value of t2 and t1 needs to be smaller as the cycle of one single can.
A production of 300/min. corresponds to a cycle time of 200 ms/can. Production of 600/min. corresponds to 100ms/can.
For a more detailed explanation of timing t1 and t2, consult your manual book 2, chapter 5.6.5. “Setting of Parameter t1 & t2 for reduced Current and Overlap Check“.
