Allen-Bradley 20BF119A0ANNANC0 AC Drive — Product Overview and Technical Catalog

1. Product Overview

The Allen-Bradley 20BF119A0ANNANC0 is a catalog number associated with the PowerFlex 700 family of industrial AC drives. This type of drive is used to control the speed and operation of three-phase AC motors in industrial machinery, material-handling systems, production equipment, and other applications that require adjustable motor speed.

The complete catalog number is important when identifying a drive for purchasing, maintenance, or replacement. Individual characters can distinguish electrical ratings, hardware configurations, enclosure options, and other features. The exact electrical rating and configuration for 20BF119A0ANNANC0 should therefore be confirmed against the drive’s nameplate or its corresponding technical documentation before installation or replacement.

2. Product Parameters

The table below separates the product’s general characteristics from specifications that still require confirmation. This avoids assigning an incorrect voltage, current rating, physical size, or weight to the exact catalog number.

Important: The physical dimensions and weight are deliberately marked as unconfirmed rather than estimated. Drives in the same product family can have different frame sizes and option assemblies, so a value taken from another model could be misleading.

Confirmed catalog configuration

For this specific catalog number, the key identifying details are:

These are the catalog-specific identifying specifications. The exact dimensions and weight for the IP20 version remain unconfirmed here; the larger dimensions listed for a standalone IP54 enclosure should not be treated as the dimensions of this IP20 unit.

3. Product Introduction

The PowerFlex 700 is an industrial AC drive designed to regulate motor speed and torque in machinery and process systems. Instead of running a motor only at its fixed supply frequency, the drive adjusts its output to help match motor operation to the requirements of the application.

The 20BF119A0ANNANC0 configuration is intended for 690 V three-phase systems and has a 119 A rated current. Its catalog description identifies vector control with 24 V I/O, without a feedback option, and without an internal braking resistor or brake IGBT. These details matter when matching the drive to an existing control panel, motor, and braking arrangement.

Because this model is discontinued, replacement planning should consider the full application rather than current rating alone. A replacement must be checked for input voltage, motor current, duty rating, enclosure, control method, I/O requirements, communications, braking needs, and physical installation dimensions.

4. Product Applications

Industrial pumps and fans

Variable-speed drives can regulate pump and fan output to match process demand. Where the motor and driven equipment are suitable, reducing unnecessary speed can help avoid throttling losses and improve process control.

Typical examples include circulation pumps, industrial ventilation fans, and utility systems. The final drive selection must account for the motor’s current, load profile, starting requirements, and the system’s operating range.

Conveyors and material handling

A drive can provide controlled acceleration and deceleration for conveyor motors. This can help reduce abrupt starts, limit mechanical shock, and coordinate movement with upstream and downstream equipment.

Applications may include packaging conveyors, assembly lines, bulk-material handling, and transfer systems. If a conveyor must stop quickly or handle an overrunning load, the required braking performance needs separate evaluation because this catalog configuration has no internal brake IGBT or drive-mounted braking resistor.

Industrial processing equipment

Speed control can help maintain a required production rate in mixers, agitators, processing machines, and other motor-driven equipment. The correct setup depends on the load’s torque characteristics and the process requirements.

Production lines and machine systems

The drive can be integrated into a control system using its available 24 V I/O. Before reusing an existing program or control cabinet, engineers should verify the signal assignments, control wiring, fault-reset behavior, interlocks, and any external communication requirements.

Existing 690 V installations

This model may be relevant when maintaining equipment designed around a 690 V three-phase supply. Since it is discontinued, the original nameplate, electrical drawings, parameter backup, and cabinet layout should be collected before choosing a replacement.

5. Product Advantages

5.1 Adjustable motor speed

The drive allows motor speed to be adjusted to suit operating requirements. This can help reduce unnecessary full-speed operation and make it easier to coordinate motor-driven equipment with the production process.

5.2 Vector-control capability

The listed configuration supports vector control. Depending on the control mode, motor data, and commissioning setup, vector control can provide more effective speed and torque regulation than simple frequency control.

Performance depends on correct motor parameters and the application. The actual control performance should be verified during commissioning.

5.3 Industrial three-phase operation

The 690 V three-phase rating makes this configuration relevant to compatible industrial power systems. Correct supply matching is essential; a drive designed for one voltage class must not be assumed compatible with another.

5.4 Integration through 24 V I/O

The catalog configuration includes 24 V I/O for control signals. This can support integration with suitable industrial control circuits, provided that signal types, terminal assignments, and electrical ratings are compatible.

5.5 Configurable acceleration and deceleration

The PowerFlex 700 family supports adjustable acceleration and deceleration settings. Appropriate ramp settings can help reduce mechanical shock during starts and stops. Actual stopping performance depends on the load, motor, drive settings, and any external braking equipment.

5.6 Industrial application flexibility

The PowerFlex 700 family has been used in a range of motor-control applications. Suitability for any particular machine still depends on motor power, load torque, environmental conditions, protection requirements, and the drive’s installed options.

5.7 Maintenance and replacement planning

A complete catalog number helps technicians identify the original configuration. For a discontinued unit, recording the nameplate information and saving the existing parameter settings can simplify troubleshooting and replacement engineering.

6. Brand and Product Series

The PowerFlex 700 series is designed for industrial motor-speed control. The exact catalog suffix is important because models within the same family can differ in current rating, voltage, enclosure, feedback capability, braking hardware, and communication options.

7. Five Related Models to Consider

The following models are candidates for comparison within the same drive family or for a related application. They should be treated as selection candidates, not confirmed drop-in replacements. Exact suffixes, ratings, dimensions, and weights must be checked against the nameplate or the technical data for each specific unit.

How to choose among these models

– For a lower-current motor: Compare the motor’s nameplate current and the application’s duty rating with the candidate drive’s actual output-current rating.

– For an existing 690 V system: Confirm the candidate’s voltage class and input requirements before considering other features.

– For a replacement installation: Compare cabinet clearances, mounting points, wiring terminals, enclosure, cooling requirements, and the installed options.

– For a machine that needs braking: Check the braking arrangement carefully. The original 20BF119A0ANNANC0 configuration does not include a brake IGBT or a drive-mounted braking resistor.

– For PLC or network integration: Check the communication hardware and control interface independently. A similar model number does not guarantee identical communications or I/O.

8. Five Other Allen-Bradley Models Worth Comparing

These models belong to related Allen-Bradley PowerFlex drive families and may be worth evaluating for new equipment or replacement projects. They are not automatically interchangeable with a 690 V PowerFlex 700 drive.

The PowerFlex 525 and PowerFlex 40 models are from different drive families. Their catalog numbers alone do not establish suitability for a 690 V motor system. Verify each model’s rated voltage and electrical specifications before considering it for the same application.

9. Installation and Replacement Considerations

Before installing or replacing the 20BF119A0ANNANC0, check the following items.

1. Power supply: Confirm the system voltage, phase, frequency, grounding arrangement, and available short-circuit current.

2. Motor: Record the motor’s rated voltage, full-load current, power, frequency, speed, and connection arrangement.

3. Load characteristics: Determine whether the application is normal duty or heavy duty, and whether it involves high starting torque, frequent acceleration, or an overrunning load.

4. Braking: Evaluate stopping time, deceleration energy, and whether external braking hardware is needed.

5. Control interface: Check the I/O wiring, command sources, feedback requirements, interlocks, and communication modules.

6. Physical installation: Confirm the exact drive dimensions, weight, mounting clearances, ventilation, cable-entry requirements, and enclosure.

7. Parameter configuration: Back up existing settings where possible, and validate motor data and control parameters during commissioning.

8. Lifecycle planning: Because this model is discontinued, assess repair, refurbishment, and engineered replacement options before committing to a substitute.

10. Product Summary

The Allen-Bradley 20BF119A0ANNANC0 is a PowerFlex 700 AC drive configured for 690 V three-phase operation, with a rated current of 119 A and stated ratings of 110 HP normal duty and 90 HP heavy duty. Its listed configuration includes IP20 / NEMA Type 1 protection, conformal coating, vector control with 24 V I/O, and no internal braking hardware or communication module.

Its key application areas include industrial motor-speed regulation, conveyor systems, pumps, fans, and production machinery, provided that the drive’s ratings and configuration match the load and installation.

The most important point when selecting a replacement is to compare the complete electrical and hardware configuration, not just the model family or current rating. The exact physical dimensions and weight of the IP20 unit have not been confirmed in this description, so they should be obtained from the corresponding dimensional drawing or measured from the actual drive before planning cabinet installation or shipment.
