Set-up
The directional control valve with IAC Multi Ethernet electronics mainly consists of:
General information
The pilot-operated IAC Multi Ethernet valve (Integrated Axis Controller based on directional control valves) is a digital directional control valve with integrated axis controller and the following functionalities:
This enables, amongst others, the following operating modes:
Function
When the control solenoid of the pilot control valve is de-energized, the spring-operated control spool of the pilot control valve is in “fail safe” position. The main stage control spool is in its spring-centered offset position at 1 ... 6 % of the stroke in direction P to B/A to T.
The integrated electronic system compares the specified command value to the actual value of the control axis. In case of a control deviation, the control solenoid is energized and the control spool in the pilot control valve is adjusted. The flow which is activated via the control cross-sections leads to an adjustment of the main stage control spool. The stroke/control cross-section of the main control spool is regulated proportionally to the command value. In case of a command value presetting of 0 %, the electronics adjust the control spool of the main stage to central position. The pilot oil is supplied to the pilot control valve either internally via port P or externally via port X. The feedback may be realized internally via port T or externally via port Y to the tank.
Failure of supply voltage
If the supply voltage fails or in case of cable break, the integrated electronics will de-energize the control solenoid, the pilot control spool will move to the fail-safe position and will unload the pilot oil chambers of the main stage. The main stage control spool is set by the spring to offset position.
Monitoring
The digital control electronics enable comprehensive monitoring functions/error detection including:
IndraWorks PC program
To implement the project planning task and to parameterize the IAC Multi Ethernet valves, the user may use the IndraWorks engineering tool (see accessories):
Pilot oil supply
The pilot control valve can be supplied with pilot oil via ports X and Y (externally) as well as from the main flow channels P and T (internally).
