CN0276 Software User Guide

OVERVIEW

CN-0276 is a high performance 10-bit to 16-bit RDC(resolver to digital converter) circuit. The system converts the modulated output of resolver to the digital output. TheAD2S1210 provided integrated solution for accurately measures angular position and velocity with resolver.

In the system AD2S1210 generated programmable excitation signals, the AD8692 and AD8397 compose third order butterworth lowpass filter and power amplifier. The resolver’s excitation signal have two amplitude options, choice by the power supply voltage automatically. The output signals of resolver pass through the third order butterworth lowpass filter made by AD8694 to the AD2S1210 inputs. Both transmit and receive filter set for improve the performance of RDC and filter out the noise to increase EMC characters.

The maximum tracking rate of the RDC is 3125 rps in the 10-bit mode (resolution = 21 arc min) and 156.25 rps in the 16-bit mode (resolution = 19.8 arc sec).

Required Equipment

General Setup


Installing the Software

  1. Extract the file CN0276_Evaluation_Software.zip and open the file setup.exe.

    NOTE: It is recommended that you install the CN0276_Evaluation_Software.zip to the default directory path C:\Program Files\Analog Devices\ (in 32-bit operational system) or C:\Program Files (x86)\Analog Devices\ (in 64-bit operational system), and all National Instruments products to C:\Program Files\National Instruments\ (in 32-bit operational system) or C:\Program Files (x86)\National Instruments\ (in 64-bit operational system)





  2. Click Next to view the installation review page



  3. Click Next to start the installation, after the installation, the installer for the ADI SDP Drivers will execute.



  4. Press “Next” to set the installation location for the SDP Drivers.

    It is recommended that you install the drivers to the default directory path
    C:\Program Files\Analog Devices\SDP\DriversR2\ (in 32-bit operational system) or C:\Program Files (x86)\Analog Devices\SDP\DriversR2\ (in 64-bit operational system)





  5. Press “Next” to install the SDP Drivers and complete the installation of all software. Click “Finish” when done.


Connecting the Hardware

  • Connect the TS2620N21E11 (resolver) to J3 of the EVAL-CN0276-SDPZ (CN-0276 Board) as depicted below.

    NOTE: If a different resolver is used other than the TS2620N21E11 from Measurement Specialties, the wiring schematic maybe different!

Using the Evaluation Software

Software Control and Indicator Descriptions





  1. Connect/Disconnect Button
    • When this button is clicked, the SDP-B Board USB connection to the CN-0276 Board status will be filliped. A connection to the SDP-B Board must be made to use the software.
  2. Start Button
    • When this button is pressed, the SDP-B Board will collect conversion data and present the acquisitions in the chart.
  3. Stop Button
    • When this button is pressed, the software stop collecting data from the CN-0276 Board.
  4. Samples setting
    • The number which input to this box is used to set the samples for each time the start button pressed.
  5. Run mode setting
    • The check box set the persistent running mode of ADC samples.
  6. Control Tabs
    • Data Analyze This Tabs showing
