ADUM5000

This evaluation board is obsolete and no longer recommended.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

Software:

Example reference designs showing how to use the platform with Xilinx^® FPGAs or SoCs and high performance control algorithms from Mathworks^® are provided together with the hardware. Information on the FMC board, and how to use it, the design package that surrounds it, and the software which can make it work, can be found by clicking the software link.

The ezLINX^™ iCoupler^® Isolated Interface Development Environment provides developers with a cost-effective, plug and play method for evaluation eight physical layer, digitally-isolated communication standards (USB, RS-422, RS-485, RS-232, CAN, SPI, I²C, and LVDS). The Blackfin^® ADSP-BF548 processor is used to run the uCLinux operating system and allows for easy customization through the open source hardware and software platform. Development time is significantly reduced for embedded designers and system architects who are designing and evaluating isolated communication standards. The interfaces on ezLINX use ADI's isolated transceivers with integrated iCoupler^® and isoPower^® digital isolator technology.

EVAL-ADuMQSEBZ can be used with most iCoupler^® and isoPower(R) isolation products in the 16-lead, wide-body SOIC and QSOP packages. The evaluation board supports the common pad positions for power, ground, and I/O pins.

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. This solution combines hardware and software with out-of-the-box functionality for a 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 kit’s motor under open or closed loop speed control in conjunction with an ADSP-CM408 EZ Kit. The software is provided as an executable file which can be flashed to the ADSP-CM408 processor using the ADI serial boot-loader utility. A .NET-based graphical user interface (GUI) is provided to enable motor start-stop, speed control, and data visualization. Sample C-code is also provided for open loop Volts/Hertz control of a motor.

The FlexMC Kit hardware comes in two variants. The kit option includes a PMSM motor with encoder, a 24V motor drive board, and a power supply. The board-only option includes the motor drive board only. In this case users can connect their own motor and power source. In both cases, the power board connects directly to an Analog Devices ADSP-CM408 Mixed-Signal Control Processor EZ Kit (sold separately). Easy connection to motors and the CM408 EZ Kit make this system perfect for your prototyping needs.

Additional rapid prototyping MATLAB/Simulink tools and support can be obtained by purchasing this kit from Boston Engineering
