Product Overview
The Allen Bradley 20BC085A3ANNACC0 PowerFlex 700 AC Drive is a variable frequency drive used for motor speed control and power management in industrial automation systems.
In manufacturing equipment and process applications, motors often need more than simple start and stop operation. The PowerFlex 700 AC Drive adjusts motor speed, torque, and operating performance according to application requirements, allowing machines to respond to changing production conditions.
The 20BC085A3ANNACC0 belongs to the PowerFlex 700 drive family and is typically installed between the electrical supply and AC motor. It processes control commands from the automation system and adjusts the motor output accordingly, making it suitable for applications involving pumps, fans, conveyors, and industrial machinery.
For maintenance engineers, this type of drive is usually involved in motor control troubleshooting, replacement projects, and production equipment upgrades. When drive-related faults occur, inspection should include incoming power, motor condition, control wiring, parameter settings, communication connections, and the complete drive system rather than focusing only on the inverter unit.

Product Features
The Allen Bradley 20BC085A3ANNACC0 PowerFlex 700 AC Drive provides adjustable motor control capability for industrial equipment.
Key characteristics include:
- Allen Bradley PowerFlex 700 series drive
- Model 20BC085A3ANNACC0
- Variable frequency motor control
- Supports industrial AC motor applications
- Used for speed and operating condition adjustment
- Integrates with automation control systems
- Suitable for machine and process equipment applications
- Used in industrial drive replacement and maintenance projects
The drive should be configured according to the motor specifications, application requirements, and control system architecture.
Working Principle
The 20BC085A3ANNACC0 operates by converting incoming electrical power into a controlled output suitable for AC motor operation.
A typical control path can be represented as:
Power Supply → PowerFlex 700 AC Drive → AC Motor → Mechanical Equipment
During operation, the drive receives control commands from the automation system or operator interface. It processes these commands and adjusts the electrical output supplied to the motor, allowing changes in motor speed and torque.
In practical applications, the drive enables equipment to operate according to process demand instead of running continuously at a fixed speed. For example, a pump can adjust output based on flow requirements, or a conveyor can change speed according to production conditions.
When diagnosing drive performance issues, engineers should evaluate:
- Drive parameters
- Motor feedback and wiring
- Incoming power quality
- Communication signals
- Mechanical load conditions
A motor control problem is not always caused by the drive itself, so the complete operating system should be checked.
Role in an Industrial Motor Control Architecture
The Allen Bradley 20BC085A3ANNACC0 operates within the motor control layer of an industrial automation system.
A simplified architecture can be viewed as:
PLC / Controller → PowerFlex 700 Drive → AC Motor → Machine Load
The PLC or control system sends operating commands, while the drive manages the electrical output delivered to the motor.
Compared with direct motor starters, an AC drive provides greater control over operating speed and acceleration behavior. This makes it suitable for equipment where process conditions change frequently or where controlled motor operation is required.
Industrial Applications
The Allen Bradley 20BC085A3ANNACC0 PowerFlex 700 AC Drive is used in industrial applications requiring adjustable motor control.
| Application | Typical Use |
|---|---|
| Conveyor Systems | Adjusting material handling speed |
| Pump Systems | Controlling flow-related motor operation |
| Fan and Ventilation Equipment | Managing motor output according to demand |
| Manufacturing Machinery | Coordinating machine movement |
| Process Equipment | Supporting variable-speed operation |
| Packaging Systems | Controlling mechanical processes |
| Industrial Production Lines | Managing motor-driven equipment |
The actual application depends on motor characteristics, system design, and production requirements.
Installation and Maintenance
Installation of the 20BC085A3ANNACC0 requires proper integration with the motor, power supply, and automation system.
Recommended maintenance procedures include:
- Verify drive model before installation
- Check input power connections
- Confirm motor compatibility
- Review drive parameter settings
- Inspect control wiring
- Check communication connections
- Monitor operating temperature
- Inspect cooling paths
- Review fault history
- Verify motor operation after commissioning
If abnormal operation occurs, engineers should review both electrical and mechanical conditions because motor performance depends on the interaction between the drive, motor, and connected equipment.

Technical FAQs
What type of applications commonly use the PowerFlex 700 20BC085A3ANNACC0?
The drive is commonly used for motor-driven equipment requiring adjustable speed control, including conveyors, pumps, fans, and industrial machinery.
What should be checked before replacing an existing PowerFlex drive?
Engineers should verify motor specifications, drive parameters, wiring connections, communication settings, and the existing installation configuration.
Why can a drive fault be caused by the motor or mechanical system?
The drive controls the motor but does not operate independently. Motor insulation issues, excessive load, mechanical binding, or incorrect feedback signals can trigger drive alarms.
What information should be reviewed after installing a replacement AC drive?
The drive configuration, operating parameters, fault records, motor response, and communication status should be checked during commissioning.
