AxisPro level 1 valves, such as KBS1-03 (ISO size 3), can be used to control machine motions in open loop or closed loop control applications. The valve receives its analog command input on the 7-pin, main, connector from an external axis control device.
AxisPro level 2 or level 3 valves, such as KBS2-03 (or KBS3-03 with sensors), can be used to control machine motion in open or closed loop control applications. The valve can receive its analog command input on the 7-pin connector from an external axis control device or, with the available on-board motion control feature activated (via Eaton Pro-FX Configure), can close the external control loop around the actuator on the valve (taking feedback signal from cylinder or motor) – eliminating the separate motion controller. In this case the AxisPro valve receives a position, speed or force command and will create its own valve command needed to comply with the requested machine motion. In addition, digital communications over the CANopen bus is available for machine control or monitoring purposes.
Built on the proven KBS servo Proportional Valve technology, Eaton’ s new AxisPro™ Proportional Valve provides a range of controls capability in a modular design. These four-way solenoid operated proportional valves offer high dynamic performance which enables them to be used in closed-loop control applications previously only possible using servo valves. Best-in-class ingression protection rated to IP65 and IP 67, combined with up to 85C (185F) ambient temperature allows operation in demanding environments.
Reliable, extended uptime is enabled by valve and systems diagnostics capability. LED lens provides on-valve diagnostics information for level-1, 2 and 3 valves. Access to systems and machine health data can be made available via CANopen networked valves and systems data collected from external sensors input to level-2 valves, or from integrated sensors on level-3 valves featuring pressure sensors in A, B, P and T ports along with temperature data sensed from the T-port.
Leverage inventory of AxisPro valves by configuration through software. One valve SKU can serve multiple needs: Level-1 valves can be configured via Eaton’s Pro-FX™ Configure software tool for optional command signal: Voltage or current, as well as activating the “enable”-pin. Level-2 and 3 valves can also have CAN bus activated and control modes selected and configured: VSC for valve-spool control, or for axis-control drive modes: DPC Cylinder position control, DSC Speed control, DFP Force/Pressure control, DPQ Pressure/Flow control. User applications can be developed in Eaton’s Pro-FX Control software tool, which is based on the popular CODESYS development environment. This feature is available option on level-2 and 3 valves allowing the use of pre-developed motion control blocks from Eaton’s Pro-FX Control library or custom developed solutions that can be loaded into a “white space” reserved in the on-board controller memory.
