Pulse Outputs Section 5-3
Operation
1,2,3... 1. An origin search is performed using the Origin Search Switch (CIO 0.02).
2. When the origin search is finished, the PCB Storage Enabled Output
(CIO 100.03) is turned ON.
3. When a PCB has been stored, the stocker is raised (relative positioning)
using the PCB Storage Completed Input (CIO 0.03).
4. Storing PCBs is repeated until the stocker is full.
5. The number of PCBs in the stocker is counted with counter C0 by counting
the number of times the stocker is raised.
6. When the stocker is full, it is moved (CIO 1.01) and only the conveyor is
lowered (absolute positioning) when stoker movement is completed (CIO
0.03).
The operation can be canceled and pulse output stopped at any point using
the Emergency Switch Input (CIO 0.05).
