DSM’s CL1 is a robust, “plug-and-play”, closed loop piezo controller based on National Instruments’ (NI) CompactRIO platform. The NI Closed Loop Piezo Controller Includes: 1. DSM Labview User Interface 2. DSM Control Firmware (loaded on the FPGA) 3. NI cRIO-9076 Real-Time Controller and LX45 FPGA 4. NI 9215 Analog Input Module or NI 9401 Digital Input Module 5. NI 9263 Analog Output Module 6. Power Supplies Add the following for a complete closed-loop system: - Piezo Amplifier(s) - Piezo Actuator(s) or Stage(s) - Closed Loop Sensor(s) including: Strain Gage, LVDT, Capacitive Probe, and/or Digital Encoder With the CL1, a user can control two independent channels of piezoelectric actuation. The system has options for both analog and quadrature feedback devices. Each analog output can drive a lownoise voltage amplifier providing accurate, low-noise piezo control. The servo loop runs at 20 kHz, automatically interpolating input position targets to ensure smooth motion. The software interfaces to a host computer running NI SoftMotion. The user can create programs in NI LabVIEW to control piezo devices.
