3.4.2 Multi - Pump Convergent & Divergent Configuration
In the Convergent & Divergent configuration, the convergent operation is the same of previous chapter.
In divergent mode, the machine operate with two independent hydraulic circuits and then allows two
independent and contemporary movement in the machine (Ex. Clamp Open and in parallel Ejector
movements). When in divergent mode the machine controller must handle a double flow/pressure profile with
two independent pressure sensor and hydraulic circuits.
Example:
The picture reported below DRV2 is in a Convergent & Divergent configuration.
When convergent Drive 1 is the master and all the other drives are slave. When in divergent mode DRV1 is
the first master DRV3 ... are the slaves of DRV1. DRV2 become a master and perform an independent
pressure and loop control.
