Overview

 

Application

The MICROMASTER 430 inverter is suitable for a variety of variable-speed drive applications. Its flexibility provides for a wide spectrum of applications. It is especially suitable for use with industrial

pumps and fans.

The inverter is especially character¬ized by its customer-oriented performance and ease-of-use. It has more inputs and outputs than the MICROMASTER 420, an optimized operator panel with

manual/automatic switchover, and adapted software functionality.

Design

The MICROMASTER 430 inverter has a modular design. The operator panels and communication modules can be easily exchanged.

Main characteristics

•    Easy, guided start-up

•    Modular construction allows maximum configuration flexibility

•    Six programmable isolated digital inputs

•    Two scaleable analog inputs (0 V to 10 V, 0 mA to 20 mA) can also be used as a 7th/8th digital input

•    Two programmable analog outputs (0 mA to 20 mA)

•    Three programmable relay outputs

30 V DC/5 A, resistive load

250 V AC/2 A, inductive load  

•    Low-noise motor operation thanks to high pulse frequencies, adjustable (observe derating if necessary)

•    Protection for motor and inverter

•    Control of up to three additional drives on the basis of PID control (motor staging)

•    Operation of drive directly on mains (with external bypass circuit)

•    Low-energy mode

•    Detects dry run of pumps (belt failure detection)

Options (overview)

•    Line commutating chokes

•    Output chokes

•    LC filter and sinusoidal filter

•    PC start-up tools, executable under Windows 98/NT/2000/ME/XP Professional

•    TIA integration with Drive ES

International standards

•    The MICROMASTER 430 inverter complies with the requirements of the EU low-voltage guideline.

•    The MICROMASTER 430 inverter has CE marking.

•    Acc. to UL and c UL certified

•    c-tick

Mechanical features

•    Modular design

•    Operating temperature: –10 °C to +40 °C (+14 °F to +104 °F)

•    Compact housing as a result of high power density

•    Detachable operator panels

•    Screwless control terminals on detachable I/O board

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 power failure or fault

•    Energy saving mode (stopping e.g. of a pump at low speeds)

•    Motor staging (connection and disconnection of additional motors, use of inverter as control drive in a pump cascade)

•    Manual/automatic mode

•    Load torque monitoring (belt failure detection; detects dry run of pumps)

•    High-grade internal PID controller for simple process control

•    Programmable acceleration/deceleration times, 0 s to 650 s
