MICROMASTER 420 Types Variable Frequency Drive Inverter Pumps Inverter

Application

The MICROMASTER 420 inverter is suitable for a variety of variable-speed drive applications.

It is especially suitable for applications for pumps, fans and conveyor systems.

It is the ideal cost-optimized frequency inverter solution. The inverter is especially characterized by its customer-oriented performance and ease-of-use. Its large supply-voltage range enables it to be used all over the world.

Design

The MICROMASTER 420 has a modular design. The operator panels and communication modules can be easily exchanged without requiring any tools.

Main characteristics

Easy, guided start-up
Modular construction allows maximum configuration flexibility
Three fully programmable isolated digital inputs
One scalable analog input (0 V to 10 V) can also be used as a 4th digital input
One programmable analog output (0 mA to 20 mA)
One programmable relay output
30 V DC/5 A, resistive load
250 V AC/2 A, inductive load
Low-noise motor operation through high pulse frequency, adjustable (observe derating if necessary)
Complete inverter and motor protection

Mechanical features

Modular design
Operating temperature: -10 °C to +50 °C (+14 °F to +122 °F)
Compact housing as a result of high power density
Easy cable connection, mains and motor connections are separated for optimum electromagnetic compatibility
Detachable operator panels
Screwless control terminals

Performance features

Latest IGBT technology
Digital microprocessor control
Flux current control (FCC) for improved dynamic response and optimized motor control
Linear V/f characteristic
Quadratic V/f characteristic
Multipoint characteristic (programmable V/f characteristic)
Flying restart
Slip compensation
Automatic restart facility following mains failure or fault
Internal PI controller for simple process control
Programmable acceleration/deceleration, 0 s to 650 s
Ramp smoothing
Fast current limit (FCL) for trip-free operation
Fast, repeatable digital input response time
Fine adjustment using a high resolution 10-bit analog input
Compound braking for rapid controlled braking
Four skip frequencies
Removable "Y" capacitor for use on IT systems (with non-grounded mains supplies, the “Y” capacitor must be removed and an output choke installed)
