Emerson Unidrive M400

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
