CN0276 Software User Guide
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).
Installing the Software
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)
to view the installation review page
to start the installation, after the installation, the installer for the ADI SDP Drivers
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)
to install the SDP Drivers
and complete the installation of all software. Click “Finish”
Connecting the Hardware
Connect the TS2620N21E11 (resolver)
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!
| J3 Pins
| TS2620N21E11 wire
Connect the adjustable DC power supplies to the J4
of the EVAL-CN0276-SDPZ (CN-0276 Board)
as following table
| J4 Pins

Establishing a USB Connection Link
Follow the instructions to properly install the software and connect the hardware as described in the previous sections.
Open the file named CN0276.exe
in the installation directory.
NOTE: If the software was installed to the default location it will be found at
C:\Program Files\Analog Devices\CN0276\CN0276.exe (in 32-bit operational system) or C:\Program Files (x86)\Analog Devices\CN0276\CN0276.exe (in 64-bit operational system)
Click the Connect Button
. A window with a progress bar will load.
Upon success, the System Status String Indicator will display SDP Board serial number
Establish a USB Connection Link
Write the configure data to AD2S1210
After power on the EVAL-CN0276-SDPZ, User must write the configure data to AD2S1210 before the first running.
Setting the sample times.
Click the Start Button.
when sample times reached the sample times setting or Stop Button has been pressed, the converting will be halt.
