The product You were Looking for was moved Click Here for new Address E-665 LVPZT Amplifier & Position Servo-Controller with High-Speed RS-232 Interface Integrated 20-Bit High-Speed RS-232 Interface Network Capability with up to 12 Channels 36 W Peak Power Position Servo-Control For Strain Gauge, LVDT and Capacitive Sensors The E-665 is a bench-top, low-voltage PZT amplifier and position servo-controller with integrated high-speed RS-232 computer interface and a 20-bit D/A converter. The E-665 supports all position sensors offered with PI piezo translators and NanoPositioning stages: strain gauge sensors, LVDT sensors and capacitive sensors. It is ideal for use with single-axis translators such as P-841 stack actuators with strain gauge sensors P-721 PIFOC® microscope objective positioners with LVDT or capacitive sensors P-620 PIHera series single-axis stages with travel up to 500 µm and capacitive sensors P-753 LISA/P-752 series NanoAutomation® stages with capacitive sensors New and Fast Communications Interface The RS-232 interface handles communications with the outside world. It performs up to 300 bidirectional read or write operations per second and incorporates precision 20-bit D/A and A/D converters for exceptional positional stability and resolution. Multi-Axis Network Up to 12 E-665s can be networked and controlled over a single RS-232 interface. PI General Command Set The E-665 is to a large extent freely programmable and its command structure conforms to the PI General Command Set. This command set is common to the E-516 Computer Control and Display Module and an increasing number of PIcontrollers, and is designed for multi-axis operation. It is PI's goal to make all of its controllers "understand" these commands, either directly or via command libraries. This will greatly reduce the effort required to produce custom programs, especially in environments which include a number of different controllers. Included with the E-665 is user-interface software as well LabView® and other driver sets. E-665.SR Screenshot of PZT-Control software for E-665. The commands listed in the editor are part of the PI General Command Set. E-665, open-loop frequency with various PZT loads. Capacitance values are in µF, measured in actual PZT.
