Product Overview
The Allen Bradley 20BC085A3ANNANC1 PowerFlex 700 AC Drive is a variable frequency drive used for controlling AC motors in industrial automation equipment and production systems.
In many industrial applications, motors operate under changing load conditions rather than at a constant speed. A drive such as the PowerFlex 700 allows the control system to adjust motor operation according to process requirements, helping equipment achieve smoother acceleration, controlled speed changes, and improved operating coordination.
The 20BC085A3ANNANC1 is part of the Allen Bradley PowerFlex 700 family and is commonly integrated into systems where motor control needs to communicate with PLCs, operator interfaces, or other automation devices. It is typically installed in control cabinets and connected between the incoming power supply and the motor circuit.
For engineers responsible for machine maintenance or system integration, this type of AC drive is often involved in conveyor systems, pumps, fans, material handling equipment, and other motor-driven applications. When troubleshooting, the drive parameters, motor condition, control signals, wiring, and mechanical load should be evaluated together.

Product Features
The Allen Bradley 20BC085A3ANNANC1 PowerFlex 700 AC Drive provides adjustable control for industrial AC motor applications.
Key characteristics include:
- Allen Bradley PowerFlex 700 series drive
- Model 20BC085A3ANNANC1
- Variable speed motor control capability
- Suitable for industrial motor-driven equipment
- Supports integration with automation control systems
- Used for machine operation adjustment
- Suitable for production equipment and process applications
- Designed for installation within industrial control environments
The drive configuration should be matched with the connected motor, application requirements, and control architecture.
Working Principle
The 20BC085A3ANNANC1 controls AC motor operation by converting incoming electrical power into a controlled output waveform suitable for motor speed regulation.
A typical operating process is:
Power Source → PowerFlex 700 AC Drive → AC Motor → Mechanical Load
The automation controller sends commands such as speed references or operating instructions to the drive. The drive processes these signals and adjusts the electrical output supplied to the motor, allowing the motor to operate according to the required process conditions.
In practical equipment operation, this enables functions such as:
- Smooth motor acceleration and deceleration
- Adjustable running speed
- Controlled machine movement
- Improved coordination between mechanical sections
During maintenance, engineers should review drive parameters and application settings because incorrect configuration can affect motor performance even when the hardware is functioning normally.
Role in an Industrial Drive System
The Allen Bradley 20BC085A3ANNANC1 acts as the motor control interface between the automation system and the mechanical equipment.
A typical system structure can be represented as:
PLC / Control System → PowerFlex 700 Drive → Motor → Machine Mechanism
The PLC or supervisory system provides operating instructions, while the drive manages the electrical power delivered to the motor.
In industrial production lines, this arrangement allows different machine sections to operate at coordinated speeds, which is especially useful for equipment involving continuous movement or variable production demands.
Industrial Applications
The Allen Bradley 20BC085A3ANNANC1 PowerFlex 700 AC Drive is commonly applied in systems requiring controlled motor operation.
| Application | Typical Use |
|---|---|
| Conveyor Equipment | Adjusting material transport speed |
| Pump Systems | Controlling motor-driven flow equipment |
| Fan Systems | Managing ventilation motor operation |
| Manufacturing Machinery | Coordinating mechanical movement |
| Material Handling Systems | Supporting variable-speed operation |
| Production Lines | Synchronizing motor-driven processes |
| Industrial Equipment Upgrades | Replacing older drive systems |
The final application depends on motor requirements, machine design, and automation system configuration.
Installation and Maintenance
The 20BC085A3ANNANC1 should be installed according to the motor specifications and existing electrical control design.
Recommended maintenance procedures include:
- Confirm the drive model before installation
- Check incoming power wiring
- Verify motor connection
- Review parameter configuration
- Inspect control terminals
- Check communication interfaces
- Maintain proper cabinet ventilation
- Review fault history
- Monitor operating conditions
- Test system operation after replacement
If a drive fault occurs, engineers should check the complete motor system rather than assuming the drive itself is the only source of the problem.

Technical FAQs
What is the main difference between the PowerFlex 700 drive and a conventional motor starter?
A conventional starter mainly controls motor starting and stopping, while the PowerFlex 700 can adjust motor operating speed and control performance during operation.
What parameters should be verified when replacing a 20BC085A3ANNANC1?
Engineers should check motor data, drive settings, control wiring, communication configuration, and the operating requirements of the connected machine.
Why might a correctly installed drive still produce motor performance issues?
Possible causes include incorrect parameter settings, motor problems, unstable input power, communication errors, or mechanical load conditions.
How does the PowerFlex 700 support industrial equipment maintenance?
The drive provides a configurable motor control platform that allows technicians to diagnose operation status, review faults, and restore equipment functionality during servicing.
