Danfoss AxisPro Servo Performance Proportional Directional Valve Owner’s Manual
AxisPro is a game changing machine control valve. Its embedded intelligence simplifies traditionally complex control practices. Plug and play design reduces machine build time, and its ability to predict potential maintenance issues increases machine reliability.
AxisPro level 1KBH valves, 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 KBH valves, 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 connec- tor from an external axis control device or, with the available on-board motion control feature activated (via Danfoss 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.
Introduction
General Description
Built on the proven KBH servo Proportional Valve technology, the AxisPro Proportional Valve provides a range of control capabilities in a modular design. These solenoid operated proportional valves offer high dynamic performance which enables them to be used in closed-loop control applications.
Unique benefits from AxisPro
Reliable, extended uptime is enabled by valve and systems diagnostics capability. LED lens provides on-valve diagnostics information for level-1 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.
Leverage inventory of AxisPro valves by configuration through software. One valve SKU can serve multiple needs: Level-1 va lves can be configured via Danfoss’s Pro-FX™ Configure software tool for optional command signal: Voltage or current, as well as activating the “enable”-pin. Level-2 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 Danfoss’s Pro-FX Control software tool, which is based on the popular C ODESYS development environment. This feature is available o ption on level-2 valves allowing the use of pre-developed motion control blocks from Danfoss’s Pro-FX Control library or custom developed solutions that can be loaded into a “white space” reserved in the on-board controller memory.

▲ Note: In applications where the valve must con-form to European RFI/EMC regulations, the outer screen (shield) must be connected to the outer shell of the 7 pin connector, and the valve body must be fastened to the earth ground. Proper earth grounding practices must be observed in this case, as any differences in command source and valve ground po-tentials will result in a screen (shield) ground loop.

Warning
Electromagnetic Compatibility (EMC)
It is necessary to ensure that the valve is wired up as above. For effective protection of the user electrical cabinet, the valve subplate or manifold and the cable screens should be connected to efficient ground points. The metal 7 pin connector part no. 934939 should be used for the integral amplifier.
In all cases both valve and cable should be kept as far away as possible from any sources of electromagnetic radiation such as cables carrying heavy current, relays and certain kinds of portable radio transmitters, etc.
Difficult environments could mean that extra screening may be necessary to avoid the interference.
It is important to connect the 0V lines as shown above. The multi-core cable should have at least two screens to separate the demand signal and monitor output from the power lines.
The enable line to pin C should be outside the screen which contains the demand signal cables.
To ensure EMI protection use only metal shielded mating connectors.
Warning
All power must be switched off before connecting/ disconnecting any plugs.

Application Data
Fluid Cleanliness
Proper fluid condition is essential for long and satisfactory life of hydraulic components and systems. Hydraulic fluid must have the correct balance of cleanliness, materials and addi-tives for protection against wear of components, elevated viscosity and inclusion of air.
The following recommendations are based on ISO cleanliness levels at 2 μm, 5 μm and 15 μm. For products in this catalog the recommended levels are:
17/15/12
Danfoss products, as any components, will operate with apparent satisfaction in fluids with higher cleanliness codes th an those described. Other manufacturers will often recomme nd levels above those specified.
Experience has shown, however, that life of any hydraulic components is shortened in fluids with higher cleanliness codes than those listed above. These codes have been prov-en to provide a long trouble-free service life for the products shown, regardless of the manufacturer.
Hydraulic Fluids
Materials and seals used in these valves are compatible with antiwear hydraulic oils, and aryl phosphate esters. The extreme operating viscosity range is 500 to 13 cSt (2270 to 70 SUS) but the recommended running range is 54 to 13 cSt (245 to 70 SUS).
Installation
The proportional valves in this catalog can be mounted in any attitude, but it may be necessary in certain demanding applications, to ensure that the solenoids are kept full of hydraulic fluid.
Good installation practice dictates that the tank port and any drain port are piped so as to keep the valves full of fluid once the system start-up has been completed.
Service Information
The products from this range are preset at the factory for optimum performance; disassembling critical items would de- stroy these settings. It is therefore recommended that should any mechanical or electronic repair be necessary they should be returned to the nearest Danfoss repair center.
The products will be refurbished as necessary and retested to specification before return. Field repair is restricted to the replacement of the seals.
