Pumps Modular Variable Frequency Drive Inverter With Variable Speed Drive

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)
