Set-up

The directional control valve with IAC Multi Ethernet electronics mainly consists of:

Direct operated directional control valve (1) with control spool and sleeve in servo quality Integrated digital axis controller (2) with: analog/digital interface (XH2) Ethernet interfaces (X7E1, X7E2) analog sensor interfaces (X2M1, X2M2) digital sensor interface (X8M)

Directional control valve with integrated axis controller, analog interfaces (X2M1, X2M2), digital interfaces (XH2, X8M) and Ethernet interfaces (X7E1, X7E2)

Functional description

The 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:

Position control Pressure/force control Closed-loop speed control Substitutional closed-loop control (position - pressure/force) Substitutional control (flow - pressure/force) pQ function (flow-controlled)

 

This enables, amongst others, the following operating modes:

Valve direct control Drive-controlled position control Drive-controlled positioning Positioning block operation The command values are preset via the Ethernet interface (X7E1 or X7E2) or, alternatively, via the analog/digital interface (XH2) The feedback information of the actual value signals to the superior control system is provided optionally either via the Ethernet interface (X7E1 or X7E2) or the analog/digital interface (XH2) The controller parameters are set via the Ethernet interface (X7E1 or X7E2)

 

Monitoring

The digital control electronics enable comprehensive monitoring functions/error detection including:

Undervoltage Communication error Cable break for analog sensor inputs and digital position measurement system Short-circuit monitoring for analog/digital outputs Monitoring of the microcontroller (watchdog) Temperature of the integrated electronics

 

IndraWorks DS PC program

To implement the project planning task and to parameterize the IAC Multi Ethernet valves, the user may use the IndraWorks DS engineering tool (see accessories):

Project planning Parameterization Commissioning Diagnosis Comfortable management of all data on a PC PC operating systems: Windows XP (SP3), Windows 7

 

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 acknowledgement" (signal fed back by the valve).

It is not possible to switch off direction P to B in a safety-relevant manner according to EN 13849-1 (depending on valve type).

Block diagram / pin assignment

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 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.
