Allen Bradley 20BD248A0ANNANC0 PowerFlex 700 AC Drive

Applications and Industrial Motor Control

The Allen Bradley 20BD248A0ANNANC0 is a PowerFlex 700 AC Drive designed for high-capacity industrial motor control applications. This configuration is rated for 480 VAC three-phase input and provides 248 A of output current, with a 200 HP normal-duty and 150 HP heavy-duty rating. It uses a Frame 6 architecture and an IP20 / Type 1 enclosure with conformal coating.

The drive is intended for industrial machinery where controlled AC motor speed, acceleration, deceleration, and reliable integration with automation equipment are required. Its 24V I/O vector-control configuration makes it suitable for applications where the drive needs to exchange control signals with a PLC or other industrial control equipment.

Typical applications include:

• Large conveyor and material-handling systems
• Industrial pumps and fluid-processing equipment
• Large fans and ventilation systems
• Compressors and rotating machinery
• Manufacturing and production equipment
• Packaging and processing machinery
• Process-control applications
• Heavy industrial machinery
• Existing PowerFlex 700 retrofit projects
• Replacement and maintenance of large-capacity AC drives

For replacement work, the complete catalog number should be verified against the original unit. The 20BD248A0ANNANC0 configuration has specific electrical and control characteristics that should be matched before installation.

Key Drive Features and Benefits

248 A output capability
The drive provides a continuous output current rating of 248 A and is specified for 200 HP normal-duty operation and 150 HP heavy-duty operation, making it suitable for substantial industrial motor applications.

480 VAC three-phase input
The configuration is designed for a 480 VAC three-phase supply. The incoming electrical system should be verified carefully before installation.

Vector control with 24V I/O
The drive uses a vector-control configuration with 24V I/O, providing a practical interface for industrial control systems and external command signals.

Frame 6 construction
The Frame 6 design accommodates the higher power level of the drive and is intended for larger industrial installations.

IP20 / Type 1 enclosure
The drive uses an IP20 / Type 1 enclosure with conformal coating. The cabinet or installation environment must provide the appropriate level of protection for the application.

No internal brake resistor
This specific configuration does not include an internal drive-mounted brake resistor or brake IGBT. Applications requiring regenerative or braking functions should therefore be engineered with the appropriate external equipment and configuration.

No communication module
The catalog configuration does not include an internal communication module. System designers should verify the required communication architecture and installed options before commissioning.

Second-environment EMC filtering
The configuration includes a second-environment EMC filter with common-mode choke, supporting installations where appropriate electromagnetic compatibility requirements need to be considered.

10 Technical FAQs

1. What is the rated output current of the 20BD248A0ANNANC0?
The drive has a continuous output current rating of 248 A. Its specified capacity is 200 HP for normal-duty operation and 150 HP for heavy-duty operation.

2. What input power does this PowerFlex 700 drive require?
The 20BD248A0ANNANC0 is designed for a 480 VAC, three-phase input supply. The actual installation should be checked against the available plant power system before connection.

3. What type of control does this drive use?
This configuration uses vector control with 24V I/O. The PowerFlex 700 platform also supports configurable motor-control methods according to the specific application and drive setup.

4. Does the 20BD248A0ANNANC0 include a built-in brake resistor?
No. This configuration has no internal drive-mounted brake resistor and no brake IGBT. If the application requires controlled braking or regenerative energy management, the braking solution must be designed separately.

5. Does this model include an internal communication module?
The 20BD248A0ANNANC0 configuration is specified without an internal communication module. The required communication architecture should therefore be evaluated separately when integrating the drive into a control network.

6. What should be checked if the drive trips on overcurrent?
Inspect the motor load, acceleration settings, motor parameters, output wiring, and mechanical condition. Excessive load, incorrect motor data, or an unsuitable acceleration profile can contribute to overcurrent conditions.

7. What motor information should be entered during commissioning?
The motor nameplate should be used to determine the applicable rated voltage, current, frequency, speed, and other required parameters. Accurate motor data is important for correct vector-control performance.

8. Can this drive be used with an Allen Bradley PLC?
Yes, the 24V I/O configuration provides a practical interface for industrial control signals. For more advanced networked control, the exact communication requirements and available options should be evaluated for the installation.

9. What environmental conditions should be considered?
The drive should be installed in an environment appropriate for its IP20 / Type 1 enclosure and operating-temperature requirements. Adequate cabinet ventilation, cleanliness, grounding, and protection from corrosive or conductive contaminants are important.

10. What should be checked when replacing an existing PowerFlex 700?
Verify the complete catalog number, supply voltage, motor current, horsepower, duty rating, frame size, control method, I/O configuration, braking requirements, communication architecture, and installed options. Existing parameters and wiring should also be documented before replacement.
