SIEMENS MICROMASTER (MM)420 frequency inverter, which can be adapted to every individual provisions without any great effort. MICROMASTER 420, the comprehensive inverter for 3-phase networks and voluntary field-bus connection from Siemens is designed for flexibility. Thanks to its modular design, the wide standard functions can be supplemented with a wide variety of options. No need for tools, as the operator panels and the communications modules can be simply plugged in. And Screw less control terminals - as with the rest of the family - make terminal connection anybody’s job
NOTICEABLE POINT
• MM420 VFD is Compact size
• MM 420 AC DRIVE Easy to commission
• Very flexible inputs and outputs
• MM420 FCC control (Flux Current Control) for high drive quality, even when load changes occur
• Dissimilar methods of commissioning, via operator panel or cost-free software tool
• Compound braking for controlled rapid braking
• 4 skip frequencies for minimizing stress on the machine when resonance occur
• Automatic restart
• Minimal stress on motor when inverter connected to rotating motor
• Modular system of inverter options
• Parameterizable acceleration/ deceleration times (0 to 650 s)
• Prepared for use in IT networks
• Integrated protection/overload functions
• Available with or without integrated EMC filter
