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

Its Strengths in Brief
- Available for mounting near the motor or as COMBIMASTER 411
- Requires less space due to compact space-saving design
- Simple assembly, installation, and maintenance
- Easily extendable due to modular design
- Motor and inverter are perfectly matched
- ECOFAST (Energy and Communication Field Installation System) is a system for decentralization without control cabinets.
- Rugged housing with high degree of protection (inverter: IP 66; motor: IP 55; IP 56/IP 65 to order); suitable for corrosive environments (epoxy resin powder coating)
|
- For communication with PROFIBUS and AS-Interface
