All data are superseded by any new release.The newest release for data sheets is available for download at www.pi.ws. R3 11/04/14.0The single-channel E-625 piezocontroller is equipped with aRS-232 and USB interface andprecision 24-bit A/D convertersfor exceptional positional stabilityand resolution. It integrates alow-noise integrated piezoamplifier which can output andsink peak currents of 120 mA forlow-voltage piezoelectric actuators.Servo-controller versionsfor position sensing with capacitiveor SGS sensors are available.PI employs proprietary positionsensors for fast response andoptimum positioning resolutionand stability in the nanometerrange and below. For high-endapplications, capacitance sensorsprovide direct and non-contactposition feedback (directmetrology). Strain gauge sensors(SGS) are available for costeffectiveapplications. The integratednotch filters (adjustableE-625.CR compact piezo servo-controller Integrated 24-Bit USB Interface Network Capability with up to 12 Channels 120 mA Peak Current Position Control with Strain Gauge or Capacitive Sensor Notch Filter for Higher Bandwidth Table for User-Defined Curves Additional Analog Interfacefor each axis) improve the stabilityand allow high-bandwidthoperation closer to the resonantfrequency of the mechanics.Multi-Axis Network for up to12 ChannelsUp to twelve E-625 for capacitiveor SGS sensors can be networkedand controlled over a singlePC interface. The different unitsare connected in parallel (notdaisy-chained) over the link providinghigher data rates thanpossible with serial links. Betweenthe individual E-625s,parallel networking is realizedvia optional E-625.CN cables.High-Resolution DigitalInterfaceThe digital interface includeshigh-precision 24-bit A/D convertersfor optimum positionstability and resolution and supportsfast communication withthe host-computer.Waveform MemoryThe built-in wave table can storeuser-defined data points internally.These values can then beoutput automatically (or underthe control of an external signal)and programmed for point-bypointor full-scan triggering.Thus, trajectory profiles can berepeated reliably and commandedeasily.Ordering InformationE-625.CRPiezo Amplifier / Servo-Controller,1 Channel, -30 to 130 V, CapacitiveSensor, USB, RS-232E-625.SRPiezo Amplifier / Servo-Controller,1 Channel, -30 to 130 V, SGS-Sensor, USB, RS-232E-625.CNNetwork Cable for Networking ofTwo E-625E-625.C0PIFOC ® Piezo Amplifier / Servo-Controller, 1 Channel, -30 to 130 V,Capacitive SensorE-625.S0PIFOC ® Piezo Amplifier / Servo-Controller, 1 Channel, -30 to 130 V,SGS-SensorExtensive Software SupportThe controllers are deliveredwith Windows operating software.Comprehensive DLLs andLabVIEW drivers are availablefor automated control.The extensive command set isbased on the hardware-independentGeneral Command Set(GCS),whichiscommontoallcurrent PI controllers for bothnano- and micropositioning systems.GCS reduces the programmingeffort in the face ofcomplex multi-axis positioningtasks or when upgrading a systemwith a different PI controller.E-625: operating limitswith various PZT loads(open-loop), capacitanceis measured in μFIdeal system configuration:E-625.CR with P-725 PIFOC ® microscopeobjective positioner
