Unidrive M400

♦ Features

Minimize downtime and system set-up time with advanced keypad options

  • Informative, multi-language, 3 line display aids set up and provides diagnostic information
  • 4 navigation buttons facilitate intuitive navigation and programming
  • Keypad options available:

+ CI Keypad – Drive mounted LCD keypad

+ Remote IP66 keypad – rapid panel mount (1 x 32mm Ø hole)

+ No Keypad – Control/programming performed by PC or fieldbus

Reduced system costs by directly integrating with applications

  • M400 incorporates an onboard PLC which can execute Machine Control Studio (IEC61131-3) programs for logic and sequencing with real-time tasks – removing the need for additional PLC’s
  • Fit an SI module to add a fieldbus communications option or additional I/O

Improve throughput with advanced openloop 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
  • Precise frequency following is possible from an encoder or frequency/direction inputs

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

  • M400 has integrated dual STO inputs for SIL3 / PLe conformity, eliminating the need for external safety components
