Emerson Unidrive M300 AC drive

Conform to safety standards, maximize uptime and reduce costs by integrating directly with safety systems

  • M300 has integrated dual STO inputs for SIL3, PLe conformity, eliminating the need for external safety components

Improve throughput with advanced open-loop motor control algorithms

  • Rotor Flux Control (RFC-A) gives maximum stability and control of induction motors at all powers.
  • 180% motor overload suitable for heavy industrial machinery applications

Flexible system integration with SI communications options

  • M300’s SI interface enables integration with a wide range of available industry standard fieldbuses and I/O

Install and configure quickly and easily

  • Simple fixed LED keypad
  • Useful parameter guide located on the front of the drive
  • Use Unidrive M Connect or an SD card with the AI-Backup adaptor to clone and transfer parameter sets
  • DIN rail mounting is supported below 1.5 kW
