Woodward High Output Digital Valve Positioner (DVP) DVP5000/DVP10000/DVP12000

High Output Digital Valve Positioner (DVP)

DVP5000/DVP10000/DVP12000

The Digital Valve Positioner (DVP) is a family of purpose-built digital electronic positioners and actuator

drivers used to control actuation systems on gas and steam turbines. The DVP is designed to control

valves and actuators with brushless DC (BLDC) motor types. The driver controls actuator/valve position

based on resolver and LVDT feedback located on the valve and/or actuator. The DVP supports both

resolver and LVDT feedback devices. The DVP5000. DVP10000. and DVP12000 use the latest in

Woodward control architecture and a robust controller to provide high-speed precise valve control. The

DVP5000 provides a nominal 5 kW output, the DVP10000 is capable of a nominal 10 kW output, and the

DVP12000 is capable of a nominal 12kW output.

The DVP5000/DVP10000/DVP12000 products are an extension of the existing DVP family. These units

are rear-panel mounted and utilize forced air cooling to provide high power output with an extended

operating ambient of -40°C to +70°C. The maximum output is 25Adc or 25Apk (17.7Arms) and the driver

accepts an input voltage from 90 V to 300 VDC, the output current for the DVP10000 and DVP12000 is

derated below an input voltage of 190 VDC. The DVP12000 can provide an increased output current of

28Adc or 28Apk (19.8Arms) when operating with select actuators in ambient temperatures between -40°C

to 55°C. For functional safety applications, the DVP5000/DVP10000/DVP12000 has an EXTERNAL

SHUTDOWN discrete input that can be used as a remote shutdown command that is independent of the

CPU. This feature is optionally available and certified to SIL3 per IEC61508. SIL certified versions are

identified by the DVP5000-S, DVP10000-S, and DVP12000-S labels on the front panel. All other I/O and

control features are identical to the existing DVP family.

The DVP10000 and DVP12000 have a power module that temporarily boosts output power as necessary

to attain the required motor performance. These packages are slightly wider, but otherwise have the

same I/O connections as the DVP5000. Some electrical specifications are different. See the Electrical

Specifications section for more details.

In this manual, the term DVP is sometimes used to more concisely describe the DVP5000. DVP10000.

and DVP12000 products.

The DVP is designed for plug-and-play installations on many Woodward valve and actuator types.

Woodward has integrated a smart technology device called an ID (identification) module into our latest

valves and actuators. When the DVP is connected to a valve or actuator equipped with an ID module, the

DVP will automatically detect the type of valve or actuator and read critical set up and calibration

information necessary to configure the driver to the valve or actuator. After the customer interface

configuration, the DVP is ready for use.

The DVP is designed to accept many different types of input commands, including Single or Dual CAN,

Analog Input (4–20 mA or 0–5 V), or Ethernet (if equipped). Woodward also provided a Service Tool that

allows users to manipulate, configure, and monitor the DVP operation status.

The Woodward DVP5000/DVP10000 and DVP12000 are suitable for +125 VDC or 220 VDC nominal

input voltage supply operation. Contact Woodward for additional voltage options.

1.2 Purpose and Scope

The purpose of this manual is to provide the necessary background information for installing and

operating the Digital Valve Positioner (DVP) appropriately. Topics covered include introduction, basic

functional description, mechanical installation, and electrical wiring. Troubleshooting and basic software

tool installation and operation is covered in this manual.

1.3 Intended Applications

The Woodward DVP5000. DVP10000. and DVP12000 are purpose-built, state-of the-art drivers for

electric actuation. These versions feature a rugged and compact design. The DVP provides positioning

based on a demand signal from the control system and monitors the health of the driver/actuator

subsystem. Multiple input type configurations allow use of the DVP with many different turbine controllers.

The DVP also supports redundant installations. The DVP provides significant advancements over the

earlier generation of the driver, including internal configurability to drive different Woodward products.

Connect all wires as shown in the plant-wiring diagram for the appropriate actuator type. Refer to the

appropriate valve/actuator manual for wiring diagrams.

• Load terminations should be applied accordingly.

• Apply general practice to ensure cables are checked from point to point. Motor and position feedback

transducer impedance are verified from line power to ground.

• Wires exposed beyond the shield should be as short as possible, not exceeding 2 inches (51 mm).

• The shield termination wire (or drain wire) should be kept as short as possible, not exceeding 2

inches (51 mm), and where possible the diameter should be maximized.

• Installations with severe electromagnetic interference (EMI) may require additional shielding

precautions. Contact Woodward for more information.

Failure to provide shielding can produce future conditions which are difficult to diagnose. Proper shielding
