Description Size 6 Component series 3X Maximum operating pressure 280 bar Nominal flow 32 l/min Features Open - Integrated, digital flow controller (IFB Multi-Ethernet) - Bus connection/service interface (Sercos, EtherCAT, EtherNet/IP, PROFINET RT, POWERLINK, VARAN) Safe - Internal safety function (can be used up to category 4/PL e according to EN13849-1) - CE conformity according to EMC Directive 2014/30/EU Product description General information The IFB Multi-Ethernet valve ( I ntegrated F ield b us) is a digital directional control valve with integrated flow controller, load-independent. The following operating modes are possible: Valve direct control Flow control Pressure/force control Pressure control/volume substitutional Torque/force control/flow Pressure control/valve direct control substitutional Substitutional control (flow – pressure/force); pQ function (flow-controlled) Communication is done via the digital Multi-Ethernet interface (X7E1 or X7E2) only. The following data may be exchanged: Command values Actual values Configuration and setting of the system control parameters Status messages, faults or warnings Set-up The directional control valve with IFB Multi-Ethernet electronics mainly consists of: Main housing with control spool (1) Control electronics with integrated fieldbus (3) Connector, voltage supply, safety shut-down (XH1) Ethernet interfaces (X7E1, X7E2) Pressure sensor sandwich plate (4) Stroke solenoid (2.1) Control solenoid with electrical position feedback (2.2) Notice: With version "V32", the control spool may rotate in case of single-sided flow through the supply flow edges (P–A or P–B) causing damage or failure of the valve. This can be solved by reduction of the pressure differential over the supply flow edge to a maximum of 80 bar or by simultaneous use of both control edges (P‒A/B‒T or P‒B/A‒T). Flow control The integrated electronics (OBE) enables load-independent control of the flow at positive command value by means of the two integrated pressure sensors in ports P and A. At negative command value, the flow is controlled from P to B. Safety function (only symbol Q5-) The integrated electronics (OBE) of the valve enable additional shut-off of a channel according to EN 13849-1 in both directions (depending on the symbol, the valve can be considered as safely shut-off). When using symbol V, the valve cannot be used in a safety-relevant manner according to EN 13849-1 while enable acknowledgment always remains 0. Thanks to the two control solenoids (enable pin D and E, low signal) at the connector (XH1), direction-dependent shut-off is enabled. The control spool of the valve is in spring-centered central position for this purpose (fail-safe position). Enable acknowledgment pin C for solenoid A and pin F for solenoid B are "high". By connecting both control solenoids (enable pin D and E, high signal), the valve can be controlled by a command value presetting (command value positive, solenoid B or command value negat
