Allen-Bradley 20G1ABE435AN0NNNNN PowerFlex 755 AC Drive

1. Product Overview

The Allen-Bradley 20G1ABE435AN0NNNNN is a high-power PowerFlex 755 AC Drive designed for large industrial motor-control applications where high output current, substantial horsepower capability, reliable speed control, and integration with industrial automation systems are required.

The product belongs to the PowerFlex 750-Series and specifically to the PowerFlex 755 product family.

This model is designed for 600 VAC, three-phase electrical systems and provides a nominal output current of 435 A.

Its primary motor-duty ratings are approximately 500 HP for Light Duty, 450 HP for Normal Duty, and 350 HP for Heavy Duty.

This makes the drive suitable for large motors used in heavy industrial machinery, material-handling systems, mining equipment, large pumps, fans, blowers, crushers, process machinery, cement equipment, and other high-power applications.

The 20G1ABE435AN0NNNNN uses a Frame 8 architecture with a Type 1 / IP20, 600 mm deep MCC-style construction.

The drive is air cooled and uses forced-air thermal management to handle the heat generated by its high-power switching components.

A major characteristic of this specific configuration is the blank / no-HIM arrangement.

This means that the drive is intended primarily for systems where operation, monitoring, commands, and diagnostics are handled through the plant control system or external interface rather than through a permanently installed local operator terminal.

The drive also incorporates embedded EtherNet/IP, making it suitable for integration into a networked industrial automation architecture.

The input arrangement is AC input with precharge and no DC terminals.

The configuration includes EMC filtering, while the catalog configuration uses the CM jumper removed arrangement.

The 20G1ABE435AN0NNNNN is an older configuration and was discontinued on June 30, 2024, with 20G1ABE435JN0NNNNN identified as the direct replacement configuration. 

4. Electrical Rating

The most important electrical characteristic of the 20G1ABE435AN0NNNNN is its 435 A output-current rating.

This places the drive in the high-power section of the PowerFlex 755 range.

The drive is designed for 600 VAC, three-phase systems.

Its principal motor-duty ratings are:

Duty Type	Motor Rating	Approximate Metric Power
Light Duty	500 HP	~373 kW
Normal Duty	450 HP	~336 kW
Heavy Duty	350 HP	~261 kW

The Light Duty rating is suitable for applications where the motor experiences relatively moderate loading and overload requirements.

The Normal Duty rating provides a substantial capacity for general industrial machinery.

The Heavy Duty rating is intended for more demanding mechanical applications where higher torque and greater overload capability are required.

The 435 A output rating is particularly useful for large motors that exceed the practical current range of smaller PowerFlex 755 configurations.

5. 600 VAC Three-Phase Design

The drive is designed for 600 VAC three-phase input.

This voltage class is commonly used in large industrial installations where substantial motor power is required.

Higher-voltage motor systems can transfer large amounts of power while keeping current within a manageable range.

For a drive in the 400–500 HP class, 600 VAC operation is particularly appropriate for large industrial electrical systems.

Typical facilities where this voltage class can be encountered include:

• Mining operations
• Cement plants
• Aggregate-processing plants
• Heavy manufacturing facilities
• Large water-treatment installations
• Process plants
• Material-handling facilities
• Industrial ventilation systems

6. 435 A Output Capability

The 435 A output rating gives the 20G1ABE435AN0NNNNN considerable motor-control capacity.

This rating is higher than the 395 A class and makes the model useful when a 395 A drive does not provide enough current margin.

At the same time, it remains below the larger 460 A and 510 A configurations in the same general family.

This provides a useful selection point for engineers who need additional capacity without immediately moving to the next larger drive size.

The 435 A configuration can be appropriate for equipment with:

• Large motor horsepower
• High starting torque
• High inertia
• Variable mechanical loading
• Frequent acceleration
• Frequent deceleration
• Heavy material handling
• Large process loads

7. Frame 8 Construction

The 20G1ABE435AN0NNNNN uses a Frame 8 construction.

Frame 8 is intended for large industrial drives.

The physical architecture provides the space necessary for high-current power electronics, bus structures, cooling components, control electronics, power connections, and associated internal components.

This is not a compact machine-mounted drive.

It is a large industrial drive normally associated with electrical rooms, MCC lineups, large control cabinets, and dedicated industrial installations.

The approximate physical envelope is:

Height: approximately 2100 mm

Width: approximately 610 mm

Depth: approximately 600 mm

Approximate overall dimensions: 2100 × 610 × 600 mm

The exact installation envelope should always be checked against the applicable mechanical drawing because cabinet configuration and installation arrangements can affect final dimensions.

8. Dimensions and Weight

Physical Parameter	Approximate Specification
Height	~2100 mm
Width	~610 mm
Depth	~600 mm
Overall Dimensions	~2100 × 610 × 600 mm
MCC Depth	600 mm
Frame	Frame 8
Enclosure	Type 1 / IP20
Cooling	Forced Air
Approximate Weight	~540 kg
Installation	Indoor Industrial Electrical Room

The physical dimensions should be regarded as engineering-planning values rather than fabrication dimensions.

For a large Frame 8 drive, installation planning is important because the equipment is both physically large and heavy.

The approximate weight is in the 540 kg class, although actual shipping or installed weight can vary according to configuration, packaging, accessories, and installation arrangement.

For transportation and installation, engineers should consider floor loading, lifting equipment, access doors, transport routes, cable entry, maintenance clearance, and ventilation.

9. Air-Cooled / Forced-Air Construction

The 20G1ABE435AN0NNNNN is an air-cooled PowerFlex 755 drive.

Large power semiconductors generate significant heat when operating at high current.

The forced-air cooling system moves air through the power section to remove this heat.

Correct ventilation is therefore an important part of installation.

The electrical room should be designed so that heated exhaust air does not circulate directly back into the drive intake.

This is especially important when several large drives are installed in the same electrical room.

10. Blank / No-HIM Configuration

One of the defining characteristics of the 20G1ABE435AN0NNNNN is the Blank / No HIM configuration.

HIM refers to the Human Interface Module.

Unlike the JN2 version, which has a handheld/local LCD interface, the AN0 configuration does not include a local HIM as part of the standard catalog configuration.

This arrangement is useful for applications where the drive is intended to be controlled and monitored from a centralized automation system.

A typical architecture can be:

PLC → EtherNet/IP → PowerFlex 755 → Motor

or:

SCADA / DCS → Industrial Network → PowerFlex 755 → Motor

This approach is common in large process plants where individual drives are installed in electrical rooms and operators interact with them through a central control system.

11. Embedded EtherNet/IP

The drive includes embedded EtherNet/IP.

This allows the drive to become part of a plant-wide industrial communication architecture.

The automation system can use network communication for functions such as:

• Start and stop commands
• Speed references
• Drive status
• Output current monitoring
• Fault information
• Warning information
• Operating status
• Diagnostic information
• Process feedback
• Control-system coordination

For large facilities containing many variable-frequency drives, embedded industrial Ethernet can substantially simplify system architecture.

It also allows drive information to be available at higher-level supervisory systems.

12. AC Input with Precharge

The input configuration is:

AC Input with Precharge, no DC Terminals

Precharge is particularly important in a large drive because the DC-link capacitors require controlled charging when the drive is initially energized.

The precharge function limits the initial charging demand and provides a controlled transition into normal operation.

The lack of standard DC terminals is also part of the defined catalog configuration.

When selecting a replacement, engineers should therefore compare not only current and horsepower but also the input and DC-bus architecture.

13. EMC Filter

The 20G1ABE435AN0NNNNN includes an EMC filter.

Electromagnetic compatibility is important in industrial environments containing multiple drives, control systems, communication networks, sensors, instrumentation, and other electronic equipment.

The filtered configuration helps address conducted and high-frequency electrical noise considerations.

The final installation should still follow appropriate grounding, bonding, cable-routing, shielding, and motor-cable practices.

The drive’s catalog configuration also specifies the CM jumper removed arrangement.

This is an important detail when comparing the older AN0 configuration with the newer JN0 replacement.

14. CM Jumper Configuration

The AN0 configuration uses:

CM Jumper Removed

The newer JN0 replacement uses:

CM Jumper Installed

This is one of the important configuration differences between the older and newer versions.

When replacing an older AN0 drive, the electrical design should not simply treat the new catalog number as an identical physical replacement.

The grounding and common-mode configuration should be reviewed as part of the modernization process.

This is particularly important in high-power installations where motor-cable length, grounding, EMC requirements, and plant electrical architecture can have a significant effect on drive operation.

15. Dynamic Braking

The standard 20G1ABE435AN0NNNNN configuration specifies:

Dynamic Braking: None

This means that the standard catalog configuration does not include an integrated dynamic-braking solution.

Many applications do not require rapid regenerative energy handling.

However, applications involving high-inertia machinery or rapid deceleration should be evaluated carefully.

Examples include:

• Large conveyors
• High-inertia rotating machinery
• Large fans
• Certain centrifuge-type machines
• Rapid material-handling equipment
• Machinery requiring frequent speed changes

Where significant regenerative energy is expected, the braking strategy should be engineered separately.

16. Product Applications

16.1 Large Conveyor Systems

Large conveyors are a natural application for this class of drive.

A heavily loaded conveyor can require substantial torque during startup.

The 435 A output rating provides sufficient capacity for large conveyor motors in many industrial installations.

25. Advantages Compared with Smaller Drives

The 20G1ABE435AN0NNNNN is not intended to compete with compact machine drives.

Its primary advantage is its ability to control substantially larger motors.

Compared with smaller drives, it provides:

• Higher output current
• Higher horsepower capability
• Larger overload capability
• Larger electrical architecture
• Larger cooling system
• Higher-power motor control
• Industrial network integration
• More substantial mechanical construction
• Greater suitability for large process equipment

26. Advantages for Centralized Automation

The no-HIM configuration is especially suitable for centralized automation.

In a modern industrial facility, the operator does not necessarily need to stand beside the drive to control the motor.

Instead, the drive can be installed in a dedicated electrical room while the operator interacts with the equipment from:

• Control room
• PLC system
• HMI
• SCADA
• DCS
• Industrial Ethernet network

This reduces the need for a local operator interface when the plant architecture already provides centralized control.

27. Advantages for Large Industrial Plants

Large plants often contain dozens or hundreds of motor loads.

Using a consistent drive platform simplifies:

• Control architecture
• Network integration
• Maintenance procedures
• Spare-parts planning
• Technician training
• Parameter management
• Fault diagnosis
• System expansion

The PowerFlex 755 architecture is particularly appropriate when large motor loads need to be integrated into a common automation environment.

28. Maintenance Considerations

Because the drive is a large Frame 8 unit, maintenance planning should take into account the physical size and weight of the equipment.

Routine inspection can include:

• Cooling-air passages
• Cooling fans
• Electrical connections
• Grounding connections
• Motor cables
• Network connections
• Environmental contamination
• Fault history
• Operating temperature
• Cabinet ventilation

Dust and contamination are particularly important in mining, cement, aggregate, and other heavy industrial environments.

Keeping the cooling path clean can help reduce thermal stress on the power components.

29. Installation Considerations

The approximate dimensions of 2100 × 610 × 600 mm should be considered when designing the electrical-room layout.

The installation should provide adequate room for:

• Incoming power cables
• Motor cables
• Control wiring
• Network cables
• Grounding
• Ventilation
• Service access
• Component replacement
• Maintenance personnel

The approximately 540 kg class weight should also be considered when planning delivery and installation.

Suitable lifting and transportation equipment should be available before the drive arrives at the site.
