MICROMASTER 411 and COMBIMASTER 411 – ECOFAST

Variable-speed Drives for Decentralised Tasks

The decentralised inverter solution for less cabling outlay and reduced cabinet space – yet more flexible and efficient when used in conjunction with ECOFAST. The ECOFAST variants of the MICROMASTER 411/ COMBIMASTER 411 series of frequency inverters contain plug-in connectors for power-supply, communication-interface and motor connections in order to enable fast and problem-free replacement in time-critical applications and are completely compatible with ECOFAST technical systems.

Typical Uses

material handling systems e.g. transfer lines; in networked systems
