Description Size 10 Component series 3X Maximum operating pressure 280 bar Nominal flow 80 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) 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 negative, solenoid A). Enable acknowledgment pin C for solenoid A and pin F for solenoid B are "low". Separate shut-off of solenoid A or solenoid B will moreover allow for the direction-dependent activation or shut-off of the drive. Notice for safe shut-off according to EN 13849-1 (Enable acknowledgment) The enable acknowledgment is not set (pin C
