Product Overview
The Allen Bradley 20DC170A0ENNANANE is a PowerFlex 700S adjustable-frequency AC drive rated at 170 A, with a normal-duty power rating of 90 kW and a heavy-duty rating of 75 kW. It operates from a 400 V three-phase AC supply and uses Phase II control with an expanded cassette and standard incremental encoder configuration. This combination is intended for industrial motor-control applications requiring regulated speed and torque within a coordinated automation system.
The PowerFlex 700S differs from a basic speed-control drive through its advanced control architecture. Phase II control supports field-oriented motor regulation, allowing the drive to manage motor response according to configured operating commands and feedback information. This is useful in machinery where speed consistency, acceleration behavior, and torque response affect the production process.
The 20DC170A0ENNANANE includes conformal coating and an EMC filter with a common-mode choke. Its specified configuration does not include a Human Interface Module, internal brake IGBT, drive-mounted brake resistor, or internal communication module. The expanded cassette and incremental encoder arrangement are also relevant when matching the drive to an existing motor-control system.
In a material-handling installation, for example, the drive can regulate a conveyor motor as the production sequence changes. A PLC coordinates sensors, interlocks, and adjacent machinery, while the drive manages the motor’s operating response. In other industrial applications, similar control functions can support machinery that requires repeatable acceleration, regulated speed, or controlled torque.
The 170 A current rating and 90 kW normal-duty rating establish the drive’s capacity under the specified operating conditions. Final application suitability also depends on the motor nameplate data, load characteristics, operating cycle, cooling conditions, and required control functions.

Working Principle
The 20DC170A0ENNANANE converts incoming three-phase AC power into a controlled electrical output for the connected motor. Its Phase II control architecture supports field-oriented control, enabling the drive to regulate motor operation according to configured speed, torque, and operating requirements.
Three-Phase AC Supply → PowerFlex 700S Drive → Controlled Electrical Output → AC Motor → Mechanical Load
The incoming supply feeds the drive’s power-conversion section, which establishes the internal DC bus and generates a controlled output for the motor. The drive adjusts its output according to the selected control mode and operating commands.
Field-oriented control manages the motor’s flux-producing and torque-producing current components. This allows the drive to regulate motor behavior across changing operating conditions. The resulting performance depends on the motor characteristics, drive parameters, and feedback arrangement.
The standard incremental encoder configuration supports applications that use encoder feedback for closed-loop motor regulation. The encoder supplies signals representing motor movement, which the control system can use to evaluate the motor’s response to a command. Correct encoder wiring and parameter configuration are therefore important during commissioning.
The onboard analog and digital I/O connects the drive to external automation equipment. A PLC can provide run commands and reference signals while monitoring configured status information. The drive handles motor regulation, while the controller coordinates the wider machine sequence.
This model does not include an internal brake IGBT or drive-mounted brake resistor. Where dynamic braking is required, the system needs a suitable external braking arrangement compatible with the drive and the load’s stopping requirements.
Role in a PowerFlex 700S Motor Control Architecture
The 20DC170A0ENNANANE serves as the motor-regulation stage between the three-phase AC supply and the connected motor. It processes operating commands and encoder feedback according to its configured control strategy, while external automation equipment coordinates the production sequence.

Technical FAQs
How should the 90 kW normal-duty rating and 75 kW heavy-duty rating be applied when selecting a motor?
The appropriate rating depends on the motor’s load profile and operating cycle. Normal-duty and heavy-duty applications impose different demands on the drive, so selection should account for motor current, torque requirements, acceleration, and expected overload conditions.
What is the purpose of the expanded cassette in this configuration?
The expanded cassette identifies the specified hardware arrangement for this PowerFlex 700S model. It is relevant when matching the drive to an existing control system or planning a replacement with the same control architecture.
How does incremental encoder feedback affect commissioning?
The encoder provides feedback signals used by compatible closed-loop control arrangements. Incorrect wiring, incompatible signals, or unsuitable feedback parameters can affect speed regulation and motor response, so the feedback path should be checked during commissioning.
What must be considered when the application requires frequent stopping?
Frequent stopping can increase the braking demands placed on the drive and motor. Because this configuration does not include an internal brake IGBT or drive-mounted brake resistor, the required braking arrangement and operating cycle must be considered as part of the system design.
