MICROMASTER® 430AC Inverters

The Simple Standard to Save Energy

The MICROMASTER 430 inverter is a variable torque drive designed for industrial variable speed fan and pump applications. The MM430 is an easy-to-use inverter characterized by linear and quadratic V/Hz control capability. User-oriented functionality includes commissioning macro, flying restart, manual/auto mode, energy consumption monitoring, pump staging, and bypass logic control. The MM430 can interface with input voltage ranges from 380V to 480V in power ranges from 10 to 125hp.

Main Characteristics

• Ready to install and operate right out of the box. • Simple commissioning macro to easily make changes in factory programming. • Side-by-side mounting. • Six fully programmable isolated digital inputs. • Two scalable analog inputs, can also be used as 7th and 8th digital inputs. • Two fully programmable analog outputs. • Three fully programmable relay outputs. • Silent motor operation is possible when using high switching frequencies. • Complete inverter and motor protection.

Performance Features

• Latest IGBT technology. • Digital microprocessor control. • Programmable, multi-point V/Hz curve, linear V/Hz control, quadratic V/Hz control. • High grade PID controller for process control with energy saving mode. • Load torque detection for dry well/belt break detection. • Integrated pump cascade control logic (motor staging). • Automatic restart following power failure or fault. • Integrated bypass control logic. • Binary Connector (BiCo) technology. • Fast, repeatable digital input response time. • Programmable acceleration /deceleration, 0s to 650s. • Multi-curve, adjustable ramp smoothing. • Fast current limit (FCL) for trip free operation. • Standard RS-485 serial port.

Variant Independent Options

Basic Operator Panel–2 (BOP–2)

With the BOP–2, individual parameter settings can be made. Values and units are shown on a 5-digit display. One basic BOP–2 operator panel can be used for several inverters and can be directly mounted on the inverter or in an enclosure door using an optional mounting kit. The BOP–2 includes Hand/Auto selection for control/setpoint changeover.

PROFIBUS Communication Module

With the optional PROFIBUS communication module, PROFIBUS–DP operation is possible up to 12MB. In addition, the BOP–2 can be attached to the front of the PROFIBUS module giving a form-fitting, operational display. The PROFIBUS module can also be powered from an external 24V supply to ensure the node remains active when power is removed from the inverter.

DeviceNet Communication Module

Optional DeviceNet Module is used for networking inverters to the DeviceNet fieldbus system. Maximum transmission rate of 500 kbaud is possible.

DriveMonitor Commissioning Tool

DriveMonitor is a Windows®-based, commissioning software package for MICROMASTER inverters. Parameter lists can be read, altered, stored, entered, and printed.
