Micromaster MM 440

Order No: 6SE6440-…..-….

The MICROMASTER 440 inverter is suitable for a variety of variable-speed drive applications. Its flexibility provides for a wide spectrum of applications. These also include cranes and hoisting gear, high-bay warehouses, production machines for food, beverages and tobacco, packaging machines etc.; i.e. applications which require the frequency inverter to have a higher functionality and dynamic response than usual.

The inverter is especially characterized by its customer-oriented performance and ease-of-use. Its large mains voltage range enables it to be used all over the world.


The MICROMASTER 440 has a modular design. The operator panels and the modules can be easiliy exchanged.

Main characteristics
  • Easy, guided start-up
  • Modular construction allows maximum configuration flexibility
  • Six programmable isolated digital inputs
  • Two scaleable analog inputs (0 V to 10 V, 0 mA to 20 mA) can also be used as a 7th/8th digital input
  • Two programmable analog outputs (0 mA to 20 mA)
  • Three programmable relay outputs (30 V DC/5 A, resistive load; 250 V AC/2 A, inductive load)
  • Low-noise motor operation thanks to high pulse frequencies, adjustable (observe derating if necessary)
  • Protection for motor and inverter
