GENERAL D/D

D636/D638 SERIES DIRECT DRIVEN SERVO VALVES

The D636 valves (flow control valves) and the D638 valves (pres-sure control valves) are Direct Drive Valves (DDV).The valves are throttle valves for 2-, 3-, 4-, 2x2-way applicationsand are suitable for electro-hydraulic control of position, speed,pressure, and power even under high dynamic requirements.

A permanent magnet linear force motor is used to drive thespool. In contrast to proportional magnet drives, the linear force motor adjusts the spool in both working directions fromthe spring-loaded middle position. This gives the servo-pro-portional valve strong actuating power for the spool, as well asgood static and dynamic characteristics.

The valve series described in this catalog have successfully passed EMC tests required by EC directive. Please refer to therespective references in the electronics section.

Our Quality Management System conforms to DIN EN ISO9901.

For over 50 years Moog has manufactured proportional con-trol valves with integrated electronics. During this time morethan 200,000 valves have been delivered. These servo controlvalves have been proven to provide reliable control, includinginjection and blow molding equipment, die casting machines,presses, heavy industry equipment, paper and lumber proces-sing, wind turbines and other applications.

BENEFITS AND FUNCTION D/DQ-, p-, pQ-FUNCTIONALITY CAN BUS INTERFACE

The valves possess full Q-(D636), p-(D638) and pQ-functionality(option, D638). They are interchangeable to valve flow func-tion and /or to operating pressure control (option). By using thepQ option of D638 series, the control of flow and pressure ispossible with just one valve. The commutation takes place accor-ding to the parameterization either via CAN bus interface, thedigital inputs or automatically by the p/Q-controller itself.

DIGITAL ELECTRONICS

The digital driver and control electronics are integrated intothe valve. The valve electronics contain a microprocessor systemwhich performs all important functions via the valve softwareit contains. The digital electronics enables the valve to be con-trolled across the entire working range, without drift andalmost regardless of the temperature.

The valves are parameterized, activated, and monitored viathe built-in CAN bus interface in accordance with the CiA stan-dard DSP 408 (device profile fluid power technology).

In addition, up to two analog input commands or digital inputs,and up to two analog actual value outputs with programma-ble functions, are available as options.

BENEFITS OF D636/D638 SERIES DIRECT DRIVE SERVO VALVES

• Direct drive with permanent magnet linear force motor that provides high actuating power, works in 2 directions

• Pilot oil not required• Pressure independent dynamics• Minimal hysteresis and high response characteristics• Minimal current requirement at and close to hydraulic null

(hydraulic null is the position of the spool at which the pressures of a symmetrical spool are equally high in both blocked working ports)

• Standardized spool position signal

• Electrical null point adjustment is parameterizable• If the electrical supply fails, a cable breaks or emergency

stop is activated, the spool returns to the predefined spring-loaded position without overshooting a workingposition (failsafe)

• Flow control and optional pressure control (on D638) with only one valve

• CAN bus interface• Optional analog/digital inputs and outputs

D636 SERIES SINGLE STAGE DIRECT DRIVE SERVO VALVE

In 4-way operation, the servo-proportional valves can be usedto control the flow in ports A and B (use as throttle valves). Toobtain the 3-way operation, close either port A or port B. If thepressure in the tank port T exceeds 50 bar (724 psi), the leak-age port Y must be used.The valves are available with zero lap, less than 3% or 10% positive lap.

4-way / 3-way-operation with failsafe function (hydraulic symbols)

2-WAY AND 2X2-WAY OPERATION

In 2-way and 2x2-way operation, the servo-proportional valves can be used to control the flow in one direction (use as throttle valves).In 2x2-way operation, the valve can be used in 2-way applica-tions for higher flows. To do this, the port P must be connectedexternally to B and A externally with T.

The permanent magnet linear force motor is a permanentlymagnetically excited differential motor. A portion of themagnetic force is already integrated with the permanentmagnet. This makes the linear force motor's power requirementconsiderably lower than that of comparable proportionalmagnets.The linear force motor drives the spool of the servo-propor-tional valve. In the zero current condition, the centering springsdetermine the starting position of the spool. The linear forcemotor enables the spool to be guided in both directions fromthe starting position; the linear force motor's actuating powerbeing proportional to the coil current. The strong forces fromthe linear force motor and the centering springs enable precisemovement of the spool, even when working against flow andfrictional forces.

FUNCTIONALITY OF THE PERMANENT MAGNET LINEAR FORCE MOTOR


GENERAL TECHNICAL DATA D/D

Q / l/min = calculated flowQN / l/min = rated flow∆p / bar = actual valve pressure drop∆pN / bar = rated valve pressure drop

Qmax = 75 l/min

During this operating mode, the spool position is controlled.The predefined command signal is proportional to a particularspool position.The command signal (spool position command) is fed to the valve electronics. A position transducer (LVDT) measures thespool's actual position and forwards this information to the valve electronics. The electronics compares the actual spoolposition and command signal, and generates a signal to drivethe linear force motor, which then brings the spool into the cor-rect position.The position command can be influenced with parameters inthe valve software (ie: linearization, ramping, dead band, sec-tionally defined amplification, etc.).

During this operating mode of the D638 valve, the pressure inport A is controlled. The predefined command signal corres-ponds to a particular pressure in port A.The command signal (pressure command in port A) is trans-mitted to the valve electronics. A pressure transducer measuresthe pressure in port A and feeds this to the valve electronics.The electronics compares the actual pressure signal and command signal and generates a signal to drive the linear forcemotor, which then brings the spool into the correct position.The pressure control function can be influenced with para-meters in the valve software (ie: linearization, ramping etc.). Thepressure regulator is carried out as an extended PID controller.In the valve software, you can set the parameters of the PIDcontroller.

The following are examples of possible combinations:• Flow control with pressure limiting control• Forced changeover from one operating mode to the other

OPERATIONAL MODES FOR SERVO VALVES

FLOW CONTROL (Q-CONTROL) PRESSURE CONTROL (p-CONTROL)

The actual valve flow is dependent on the spool and the pres-sure drop across the spool lands.

At 100% command signal (i.e. +10V DC = 100% valve opening),the valve flow at rated pressure drop ∆pN = 35 bar per meter-ing land is the rated flow QN. For other than rated pressure,drop the valve flow changes at constant command signal accord-ing to the square root function for sharp edged orifices.

VALVE FLOW CALCULATIONS

This is a combination of flow and pressure control for whichboth command signals (flow and pressure command) must bepresent.

SIGNAL AND WIRING FOR VALVES WITH ANALOGUE ACTIVATION/CONTROL DRIVE POSSIBILITY

Command signal 0 to 10 mA (D638), floatingCommand signal 0 to ±10 mA (D636), floatingValves with current command input

The spool stroke of the valve for the volume flow function isproportional ID = – IE at 6+PE pole connector resp. I4 = – I5(at I7 = 0) at 11+PE pole connector.The command, signal ID = +10 mA resp. I4 = +10 mA equals100 % valve opening P A and B T . At 0 mA command the spool is in center position. At D638 in pressure function (0 to 10 mA), the pressure is atport A of the valve proportional ID = –IE at 6+PE pole connectorresp. I7 = – I5 (at I4 = 0 mA) at 11+PE pole connector. ID = +10 mA resp. I7 = +10 mA equals 100% regulated pressure.

Command signal 0 to 10 V (D638)Command signal 0 to ±10 V (D636)Valves with voltage command input

The spool stroke of the valve at volume flow function is pro-portional (UD –UE) at 6+PE pole connector resp. (U4 – U5) at11+PEpole connector. The command signal (UD – UE) = +10 V resp. (U4 – U5) = +10 Vequals 100 % valve opening P A and B T .

For 0 V command the spool is in central position. For D638 in pressure function (0 to 10V), the pressure at port Aof the valve is proportional to (UD – UE) at 6+PE pole connectorresp. (U7 – U5) at 11+PE pole connector. (UD – UE)= + 10 V resp.(U7 – U5)= + 10 V equals 100% regulated pressure.

Actual value 4 to 20 mA

The actual spool position value (not valve) for flow volume resp.pressure at port A at pressure function, can be measured at pinF (6+PE pole connector) resp. at pin 6 and 8 at 11+PE poleconnector (see diagrams below). Those signals can be used formonitoring and fault detection purposes. The spool stroke resp.pressure range corresponds to 4 to 20 mA. At 12 mA spool position signal the spool is in centered position.20 mA equals 100% valve opening P A and B T.

The position signal output 4 to 20 mA allows to detect a cablebreak when IF = 0 mA.

D/DHYDRAULIC WITH FIELD BUSGENERAL

GENERAL

Modern automation technology is characterised by an increas-ing decentralization of processing functions via serial data com-munication systems. The use of serial bus systems instead ofcoventional communication technology, ensures the increased

flexibility of systems in terms of modifications and expansions.It also has a tremendous potential for savings in project andinstallation costs in many areas of industrial automation.

VDMA PROFILE

CANopen

In one working group within the German Machinery and PlantManufacturers’ Association, a VDMA profile was created incollaboration with numerous well-known hydraulic systemmanufacturers. This profile describes communication between

hydraulic components via a field bus. It defines uniform functionsand parameters in a standardized exchange format.

The first field bus to be used in the hydraulics system is the CANbus. It was originally developed for use in automobiles, but hasbeen used in mechanical engineering in a variety of applica-tions. The CAN bus is primarily designed for transmission security and speed.

The CAN bus has the following overlapping characteristics:

• Multi-master system: Each participant can transmit and receive.

• Topology: Linear structure with short stub line.,• Network extension: 25 meters at 1 Mbit/s

up to 5000 meters at 25 kbit/s.• Addressing type: message-oriented via identifier.

Priority assignment of the message via identifier.• Security: Hamming distance = 6, i.e. up to

6 individual errors/messages are recognized.

Based on the short data field of 64 bits (8 bytes), total telegramlength is 111 bits. With a maximum transmission rate of 1 Mbit/sthis corresponds to a total transfer time of 111 µs. The hightransmission rate allows for closing the control loop via the fieldbus.

Other parameterization and improved diagnosis capabilitiesand the reduction of the number of variants, are some of thebenefits possible when using a field bus.
