AD2S1210

The EVAL-AD2S1210SDZ is a full featured evaluation board designed to allow the user to easily evaluate all the features of the AD2S1210 resolver-to-digital converter (RDC). The SDP board (EVAL-SDP-CB1Z) allows the evaluation board to be controlled through the USB port of a PC using the evaluation board software available for download from the AD2S1210 product page.

The FlexMC Motor Control Development Platform^TM is a rapid development system for any motor control solution. The FlexMC Kit^TM enables you to accelerate time-to-market and increase performance with powerful model-based design tools. The ADI/Boston Engineering solution combines hardware and software with out-of-the-box functionality for permanent magnet synchronous motor (PMSM) with hall sensor, encoder, or sensorless feedback.

Solution Overview

 The FlexMC Kit has the hardware and software required to spin the motor under open or closed loop speed control. With the FlexMC Kit, you model your system in MATLAB and Simulink, generate the C code, and then deploy. Utilizing system modeling and design concepts, the FlexMC Kit also contains libraries in MATLAB and Simulink for additional access to proven methodologies. The FlexMC Kit hardware includes a PMSM motor with encoder and a Boston Engineering universal AC input drive board that connects directly to an Analog Devices ADSP-CM408 Mixed-Signal Control Processor EZ Kit. Users can prototype with PC power using MATLAB and Simulink, then deploy with the FlexMC Kit. Easy connection to motors and the ADSP-CM408 EZ Kit make this system perfect for your prototyping needs.

Hardware:

This evaluation board is obsolete and no longer recommended.

The AD-FMCMOTCON2-EBZ is a complete high performance servo system on an FPGA Mezzanine Card (FMC) board, the purpose of which is to provide a complete motor drive system demonstrating efficient and high dynamic control of three phase PMSM and induction motors up to 48V and 20A.

Two motors can be driven at the same time, each motor having its separate power supply. The system incorporates high quality power sources; reliable power, control, and feedback signals isolation; accurate measurement of motor current & voltage signals; high speed interfaces for control signals to allow fast controller response; industrial Ethernet high speed interfaces; single ended Hall, differential Hall, encoder and resolver interfaces; digital position sensors interface; flexible control with a FPGA/SoC interface.

The kit consists of two boards: a controller board and a drive board. An optional AD-DYNO2-EBZ dynamometer can also be purchased through Avnet and is intended to be an extension of the drive system.

Controller Board

• Digital board for interfacing with the low and high voltage drive boards
• Compatible with all Xilinx FPGA platforms with FMC LPC or HPC connectors
• FMC signals voltage adaptation interface for seamless operation on all FMC voltage levels
• Fully isolated digital control and feedback signals
• Isolated Xilinx XADC interface
• 2 x Gbit Ethernet PHYs for high speed industrial communication, with 3rd party EtherCAT support
• Single ended Hall, Differential Hall, Encoder, Resolver interfaces
• Digital sensors interfaces
  • EnDat
  • BISS Interface

Drive Board

• Drives motors up to 48V @ 20A
• Drives 2 motors simultaneously
• High frequency drive stage implemented with ADI isolated gate drivers
• Supported motor types
  BLDC
  PMSM
  Brushed DC
  Stepper (bipolar / unipolar)
• Integrated over current protection
• Reverse voltage protection
• Current and Voltage measurement using isolated ADCs
• BEMF zero cross detection for sensorless control of PMSM or BLDC motors
• Separate voltage supplies for the 2 motors so that the motors don't influence each other

Dynamometer System with Embedded Control

• Two BLDC motors connected by a rigid couple in a dyno setup, which can be used to test real-time motor control performance.
• One BLDC motor acts as an electronically adjustable load and is driven by the embedded control system. This motor can be directly connected to the FMC motor drive to get complex / active loads. The load can be driven also by the AD-FMCMOTCON2-EBZ to implement dynamic load profiles.
• The other BLDC motor is driven by the FMC motor drive.
• Measurement and display of load motor current
• Measurement and display of load motor speed
• External control using Analog Discovery and MathWorks Instrumentation Control Toolbox
