Product description
General information
The pilot-operated 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)
Among others, the following operating modes are possible:
- 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)
Set-up
The directional control valve with IAC Multi Ethernet electronics mainly consists of:
- Pilot control valve (1) with control spool and sleeve in servo quality
- Main stage (2) with centering springs and position feedback
- Integrated digital axis controller (3) with:
- analog/digital interface (XH2)
- Ethernet interfaces (X7E1, X7E2)
- analog sensor interfaces (X2M1, X2M2)
- digital sensor interface (X8M)
- Interface for the position transducer of the main stage (X8A)
Function (symbol V, V1- and Q3)
When the control solenoid of the pilot control valve is de-energized, its spring-operated control spool is in the “fail safe” position. The control spool of the main valve is in the spring-centered offset position at approx. 6 % of the
stroke in direction P→B/A→T.
The integrated electronics (OBE) compare the specified command value to the position actual value of the control spool of the main stage. In case of a control deviation, the control solenoid of the pilot control valve is activated and its control spool is adjusted.
The flow which is activated via the control cross-sections at the pilot control valve leads to an adjustment of the control spool of the main valve. The stroke/control cross-section of the main valve is regulated proportionally to the command value. In case of a command value presetting of 0 %, the electronics adjust the control spool of the main valve to central position.
The pilot oil supply in the pilot control valve is either internal via port P or external via port X. The feedback can be internal via port T or external via port Y to the tank.
Switching off the release (symbol V and V1-)
If the supply voltage fails or in case of cable break, the integrated electronics will de-energize the control solenoid, the pilot control spool will move to the fail-safe position and will unload the pilot oil chambers of the main valve. Operated by the spring, the main valve control spool will move to the offset position (approx. 6 % P→B/A→T).

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

Notes:
- Symbol V and V1-:
Pilot-operated 4/3 directional control valves are only functional in the active control loop and do not have a locking 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.
- Symbol E. and W.:
Pilot-operated 4/3-directional control valves with positive overlap are functional in controlled or regulated axes. The overlap in the de-energized state is approx. 20 % of the control spool stroke.
While the release is being switched off, the drive may be accelerated for a short time in functional direction P→B. (For further details, please refer to operating instructions 29391-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
- Connect the valve to the supply voltage only when this is required for the functional sequence of the machine.
- 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.

Notices:
- Tighten the M12 connector with a manual torque wrench by 1 Nm.
- Self-locking M12 cables must be used.
- It must be ensured that cables are secured without radial forces.
- All cables connected to XH1, X7E1 and X7E2 must be bundled in a wire harness after 20 cm the latest. The wire harness must be fixed after further 20 … 30 cm. Make sure that there is no relative motion between the fixation and the valve.
- Before the fixation point, there must not be any cable loops.
- In general, the information on installation provided by the cable manufacturers must be observed.
- Respectively, the cables of X2M1, X2M2 and X8M, if used, are also fixed as described above.
- For further information, see operating instructions 29391-B
