Introduction

The Allen Bradley 20DC043A0EYNANANK PowerFlex 700S AC Drive is a 400V-class industrial motor controller built for applications requiring advanced speed and torque regulation. It combines the Phase II control platform with an expanded cassette and standard incremental encoder feedback configuration.

This catalog configuration is rated at 43 A, with 22 kW normal-duty and 18.5 kW heavy-duty motor ratings. It also includes a brake IGBT, EMC filter, and common-mode choke. Since no communication module or embedded communication is included, system integrators should verify the required network interface before installation.

The model is discontinued, making it particularly relevant to maintenance, repair, and spare-parts sourcing for existing PowerFlex 700S installations. When purchasing, verify the complete catalog number because other 20DC043 configurations may have different communication, control, and feedback options.

Advantages

Advanced Phase II motor control

The drive uses the PowerFlex 700S Phase II control platform, supporting field-oriented motor control for applications requiring accurate speed and torque regulation.

400V three-phase operation

Designed for 380–400V class industrial power systems, the drive provides a 43 A output rating for its specified normal-duty and heavy-duty applications.

Encoder feedback support

The standard incremental encoder configuration supports feedback-based motor control when correctly connected and configured.

Integrated braking transistor

A brake IGBT is installed, allowing the drive to work with a suitably selected external braking resistor when the application requires dynamic braking. The drive does not contain an internal braking resistor.

EMC filtering

The configuration includes an EMC filter and common-mode choke to support electromagnetic compatibility in suitable industrial installations.

Configurable motor operation

Independently adjustable acceleration and deceleration settings help engineers adapt motor response to machine requirements and operating cycles.
