Unidrive M400

 Unidrive M400

Fast set-up and diagnosis with real-text display, integrated PLC and safety inputs

0.25 - 110 kW (0.33 - 150 hp)

100 V / 200 V / 400 V / 575 V / 690 V

Unidrive M400 minimizes downtime with an intuitive LCD display for rapid set-up and clear diagnostic help. The integrated PLC can execute a substantial range of sequencing and logic programs. Coupled with an impressive I/O count complete with two STO inputs and an SI interface for a fieldbus option or extended I/O, the feature set ensures M400's flexible integration with any system. M400 provides an upgrade path for existing Commander SK users who use LogicStick.

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
