The following operating modes are possible: Standard: Valve direct control Flow control Version "5" or with internal pressure sensors: Pressure/force control Active damping Substitutional control (flow – pressure/force); pQ function (flow-controlled) Command value presetting is done purely digitally via the Ethernet interface (X7E1 or X7E2) The feedback information of the actual value signals to the superior control system is provided via the Ethernet interface (X7E1 or X7E2) The controller parameters are set via the Ethernet interface (X7E1 or X7E2) Set-up The directional control valve with IFB Multi-Ethernet electronics mainly consists of: Direct operated directional control valve (1) with control spool and sleeve in servo quality Integrated fieldbus (3) with: connector, voltage supply, safety shut-down (XH1) Ethernet interfaces (X7E1, X7E2) Analog sensor interfaces (X2N, optional) 4WRPFH 6 …G..D90 Function When the control solenoid of the valve is switched off (enable pin D, low signal), the spring-operated control spool is in the fail-safe position. When the control solenoid is activated (enable pin D, high signal), the digital electronics (OBE) compares the specified command value to the position actual value. In case of control deviations, the control of the solenoid is changed so as to be compensated. Due to the change in magnetic force, the control spool is adjusted against the spring. Stroke/control spool cross-section is regulated proportionally to the command value. In case of a command value presetting of 0, the electronics adjusts the control spool against the spring to central position. In deactivated condition, the spring is untensioned to a maximum and the valve is in fail-safe position. Notice for safe shut-off according to EN 13849-1 (enable acknowledgment) The enable acknowledgment is not set (pin C). If the supply voltage fails or in case of cable break, the integrated electronics (OBE) will de-energize the control solenoid and the control spool will move to the fail-safe position. The enable acknowledgment is also not set if the control spool is not in a hydraulically safe position (insufficient safety overlap of the control spool). Safety function The integrated control electronics of the valve enables the additional shut-off
