Additional Details

The ADM2486 differential bus transceiver is an integrated, galvanically isolated component designed for bidirectional data communication on multipoint bus transmission lines. It is designed for balanced transmission lines and complies with ANSI EIA/TIA-485-A and ISO 8482: 1987(E).

The device employs Analog Devices iCoupler^® technology to combine a 3-channel isolator, a three-state differential line driver, and a differential input receiver into a single package. The logic side of the device is powered with either a 5 V or a 3 V supply, and the bus side uses an isolated 5 V supply.

The ADM2486 driver has an active-high enable feature. The driver differential outputs and the receiver differential inputs are connected internally to form a differential input/output port that imposes minimal loading on the bus when the driver is disabled or when VDD1 or VDD2 = 0 V. Also provided is an active-high receiver disable feature that causes the receive output to enter a high impedance state.

The device has current-limiting and thermal shutdown features to protect against output short circuits and situations where bus contention may cause excessive power dissipation. The part is fully specified over the industrial temperature range and is available in a 16-lead, wide body SOIC package.

Applications

Isolated RS-485/RS-422 interfaces
PROFIBUS networks
Industrial field networks
Multipoint data transmission systems

OBSOLETE: AD-FMCMOTCON2-EBZ Evaluation Board

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This evaluation board is obsolete and no longer recommended.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 Detail

This evaluation board is obsolete and no longer recommended.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.
