Product description
General information
The IFB Multi-Ethernet valve (Integrated Fieldbus) is a digital directional control valve with integrated fieldbus.
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 of a channel according to EN 13849-1 in the direction P to A (depending on the application,
the fail-safe position must be adhered to).
For this purpose, a suitable control system must be provided to perform the plausibility check between the direction-dependent valve signals "enable input" and "enable acknowledgment" (signal fed back by the valve).
It is not possible to switch off direction P→B in a safety-relevant manner according to EN 13849-1 (depending on valve type).
Monitoring
The digital control electronics enable comprehensive monitoring functions/error detection including:
- Undervoltage
- Communication error
- Cable break for analog sensor inputs
- Monitoring of the microcontroller (watchdog)
- Temperature of the integrated electronics
IndraWorks DS PC program
To implement the project planning task and to parameterize the valve, the user may use the IndraWorks DS engineering tool (see accessories):
- Project planning
- Parameterization
- Commissioning
- Diagnosis
- Comfortable administration of all data on a PC
- PC operating systems: Windows 7-10
Notice:
4/3 directional control valves are only functional in the active control loop and do not have a leakage-free basic position when deactivated. Consequently, "external isolator valves" are required in many applications and must be taken into account regarding the switch-on/switch-off order.
While the electrical supply voltage is being switched off, the drive may be accelerated for a short time in functional direction P→B.

Detailed description of the safety function:
After the signal at the enable input has been removed, the output stage, and thus the solenoid of the valve, are internally separated from the available supply voltage. The enable acknowledgment will only be activated after the safe valve spool position has been achieved.
For a detailed description of the safety function, refer to the operating instructions 29391-B.

Project planning information
Project planning and maintenance instructions
- The supply voltage must be permanently connected, as otherwise bus communication is not possible.
- If electro-magnetic interference is to be anticipated, suitable measures must be taken to ensure the function (depending on the application, e.g. shielding, filtration).
- The devices have been tested in the plant and are supplied with default settings.
- Only complete devices can be repaired. Repaired devices are returned with default settings. User-specific settings will not be applied. The machine end-user will have to retransfer the corresponding user parameters.
