Description

The Servo PositionController (SPC) is a servovalve driver that accepts aDeviceNet™ * or (4 to 20)mA based position demandsignal from a systemcontroller, and accuratelypositions proportional orintegrating servo-valves.The SPC has the requiredaccuracy, responsiveness, and redundancy required for steam or gas turbine fuelvalve control. For valve position sensing, the SPC accepts feedback signals fromone or two (redundant) ac devices or one dc device.A Windows based software program is used to configure the SPC, adjust tunables,and monitor parameters via a personal computer. 

For ease of service, SPCconfigurations can be done while connected or disconnected to the unit. Once aconfiguration has been created, this program allows configurations to be uploadedand downloaded to other SPCs as desired.The SPC’s position feedback circuit includes integral excitation and signalconditioning circuitry for LVDT and RVDT based position sensing devices.  

The SPC is a field programmable servo-driver that controls one integrating orproportional servo-valve, and accepts single or dual feedback signals for valveposition sensing.This compact digital driver can be commanded (controlled) via a DeviceNet basednetwork, and functions as a DeviceNet (Group II only) slave device on this network.As an alternative or backup to DeviceNet, a (4 to 20) mA input signal can be used tocommand servo position.The SPC’s associated PC interface software program allows a user to configure,auto-calibrate, dynamically adjust, and manually stroke the controlled servo. Autocalibration routines make servo setup easy and greatly reduce installation times.The SPC driver is classified for heavy industrial environments, and can be easilybulkhead mounted in IP20 locations.
