2.2
Multi-stage speed control/Multi-stage pressure control, and shockless control functions
◆
The Super Unit enables multi-stage pressure control/flow rate control by selecting 16 patterns of P-Q
characteristics that have been registered in the controller from the master machine.
◆
The Super Unit enables shockless control by setting/adjusting the rising/falling time at changes of the P-Q
characteristics.
2.3
Simplification of the system
◆
The functions that have been controlled by valves in a conventional system can be controlled by pumps.
Therefore, when this system is used for high-speed/low-speed switching (for a press etc.) and multi-stage
pressure control applications, the system configuration can be simplified, and costs can be reduced.
