Product Details

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.

OBSOLETE: AD-FMCMOTCON2-EBZ Evaluation Board

Buy Now View Details

Features and Benefits

This evaluation board is obsolete and no longer recommended.

The FMCMOTCON2 evaluation kit enables users to:

Model and implement motor control algorithms rapidly for high performance servo systems, incorporating system modelling and design concepts using Mathworks model based design
Reduce time needed to move a motor control system from concept to production, by providing a prototyping system to verify the hardware and control algorithms before moving to production stage.

Product Details

This evaluation board is obsolete and no longer recommended.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.

ADuM1250 Evaluation Board

Features and Benefits

Access to two bidirectional data channels
Multiple connection options
Support for active probes
Provisions for cable terminations
Support for PCB edge mounted coaxial connectors
Easy configuration

Product Details

The EVAL-ADuM1250EBZ supports two bidirectional channels for evaluation of isolated I2C interfaces in 8-lead SOIC packages. The evaluation board provides a JEDEC standard, 8-lead SOIC_N pad layout. This layout supports signal distribution, loopback, and loads referenced to the VDDx or GNDx planes, as well as optimal bypass capacitance. Signal sources can be conducted to the board through header pins or through edge mounted Sub- miniature Version A (SMA) connectors (SMA connectors must be ordered separately).

Screw terminal blocks on the evaluation board provide power connections. The board includes 200 mil (5.08 mm) header positions for compatibility with active probes (probe header pins must be ordered separately). The EVAL-ADuM1250EBZ evaluation board can be used to evaluate the ADuM1250, ADuM1251, ADuM2250, and ADuM2251 devices. Although the pad layout on the EVAL- ADuM1250EBZ does not support the ADuM2250 and ADuM2251 16-lead SOIC_W and SOIC_IC packages, these devices are functionally equivalent to the ADuM1250 and ADuM1251, respectively, for the purposes of evaluation. They differ only by package and isolation capabilities. Therefore, evaluations of the ADuM1250 and ADuM1251 can be applied to the ADuM2250 and ADuM2251 as well.

The evaluation board follows best printed circuit board (PCB) design practices for 4-layer boards, including a full power and ground plane on each side of the isolation barrier. No other electromagnetic interference (EMI) or noise mitigation design features are included on this evaluation board. For high speed operation, or when ultralow emissions are required, refer to the AN-1109 Application Note for additional evaluation board layout techniques.

Full specifications for the ADuM1250 are available in the ADuM1250 data sheet, which must be consulted in conjunction with User Guide UG-1100 when working with the evaluation board.
