产品详情

AD2S1210是一款10位至16位分辨率旋变数字转换器,集成片上可编程正弦波振荡器,为旋变器提供正弦波激励。

转换器的正弦和余弦输入端允许输入3.15 V p-p ± 27%、频率为2 kHz至20 kHz范围内的信号。Type II伺服环路用于跟踪输入信号,并将正弦和余弦输入端的信息转换为输入角度和速度所对应的数字量。最大跟踪速率为3125 rps。

AD2S1210-EP 支持国防和航空航天应用(AQEC) 。

产品聚焦

1. 比率跟踪转换。Type II跟踪环路能够连续输出位置数据,且没有转换延迟。它还可以抑制噪声,以及参考和输入信号的谐波失真容限。
2. 系统故障检测。故障检测电路可以检测旋变的信号丢失、超范围输入信号、输入信号失配或位置跟踪丢失。各故障检测阈值可以由用户单独编程,以便针对特定应用进行优化。
3. 输入信号范围。正弦和余弦输入端支持3.15 V p-p ± 27%的差分输入电压。
4. 可编程激励频率。可以轻松地将激励频率设置为2 kHz至20 kHz范围内的多个标准频率。
5. 3倍格式位置数据。通过16位并行端口或4线串行接口可以访问10位至16位绝对角位置数据。增量式编码器仿真采用标准A-quad-B格式,并提供方向输出。
6. 数字速度输出。通过16位并行端口或4线串行接口可以访问10位至16位带符号的数字量速度。

EVAL-FMCMOTCON2 电路图

产品详情

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.
