TIDA-01600 Reference Design

Texas Instruments

Smart Brake Control and Diagnostics Reference Design for Servo Drives and Robotics

Description

This reference design implements safe brake control functionality in servo drives as per IEC EN 61800-5-2 by providing two channel output signals to control an external holding brake. The holding brake will be latched when the power supply is cut off and released when voltage is applied to the coil. This is accomplished by enabling/disabling the smart electronic load switches that supply power to the coil. This reference design also includes diagnostic features for detecting various faults, ensuring safe operation. TIDA-01600 uses the C2000 Launchpad to generate the brake control signals and to perform the diagnostics functionality.

Features
  • Implementing safe brake control meeting the requirements as specified in the EN 61800-5-2
  • 24V rated holding brakes with current of up to 2A can be controlled via isolated control signals
  • Dual switch control enhancing safe operation
  • Self-diagnostics features covering open load detection and over current protection
  • High side switch failure detection
  • Rapid application of the holding brake by fast reduction of the holding brake current
  • Optional reduction of voltage at holding brake output to reduce power consumption
Applications
  • AC Drive Power Stage Module
  • Servo Drive Power Stage Module
Product Categories
  • Isolation
