Allen-Bradley 20G1ANC205JN0NNNNN PowerFlex 755 AC Drive – Detailed Product Description, Parameters, Applications and Related Models

1. Product Overview

The Allen-Bradley 20G1ANC205JN0NNNNN is a PowerFlex 755 air-cooled AC drive designed for large three-phase motor control applications requiring high output current, adjustable speed, controlled acceleration and deceleration, and network-based drive integration.

This model is rated for 400 VAC, three-phase input, with a rated output current of 205 A. Its published power ratings are 110 kW for Normal Duty (ND) and 90 kW for Heavy Duty (HD).

The drive uses a Frame 6 mechanical platform and an IP20/IP00, NEMA/UL Open Type construction. It uses forced-air cooling and an AC input stage with precharge. The catalog configuration has no DC input terminals, embedded EtherNet/IP, an EMC filter configuration, and the CM jumper installed.

The exact catalog configuration specifies no internal dynamic-braking transistor and a blank/no-HIM configuration.

The model is part of the Allen-Bradley PowerFlex 755 family, a large-drive platform intended for industrial machines, process equipment, material-handling systems, pumps, fans, compressors, and other applications where a conventional fixed-speed motor starter does not provide sufficient speed or torque control.

The combination of a 205 A current rating and Frame 6 construction places this model in the higher-power range of the PowerFlex 755 air-cooled drive family.

The 205 A output rating is the key electrical characteristic of this model. The drive can be selected for motors up to approximately 110 kW in Normal Duty service, while the Heavy Duty rating is 90 kW.

The difference between Normal Duty and Heavy Duty ratings is important during drive selection. Normal Duty applications generally have lower overload requirements, while Heavy Duty applications require greater short-term torque and overload capability. The motor nameplate current and actual load profile should always be checked before final selection.

---

3.2 Input and Output Configuration

The 20G1ANC205JN0NNNNN uses an AC input with precharge. The precharge function controls the initial charging of the DC bus and helps manage the electrical stress associated with energizing the drive.

This model does not provide DC terminals in the specified configuration. It is therefore primarily selected as a conventional AC-input drive rather than as a common-DC-bus or DC-input configuration.

The drive is designed for three-phase industrial power systems in the 400 VAC class.

For installation, the incoming supply voltage, short-circuit current, protective device arrangement, grounding system, motor cable arrangement, and local electrical requirements should be checked against the actual installation.

---

4. Normal Duty and Heavy Duty Ratings

Normal Duty

The 20G1ANC205JN0NNNNN has a 110 kW Normal Duty rating at the 205 A current class.

Normal Duty selection is appropriate for loads where the motor normally operates without severe cyclic overloads and where the application does not require the higher overload capability associated with Heavy Duty service.

Typical examples include centrifugal pumps, centrifugal fans, blowers, cooling equipment, and other variable-torque machinery.

Heavy Duty

The Heavy Duty rating is 90 kW.

Heavy Duty selection is more appropriate for applications with higher starting torque, frequent acceleration, load changes, conveyors, mixers, positive-displacement equipment, and other machinery where the motor may experience significant transient loading.

When the load has high inertia or frequent acceleration and deceleration, the Heavy Duty rating should be considered rather than selecting the drive solely from the motor’s nominal kW value.

---

5. Mechanical Dimensions and Weight

The 20G1ANC205JN0NNNNN uses the Frame 6 open-type mechanical platform.

The standard Frame 6 dimensions for the IP00/IP20 open construction are approximately:

Mechanical Parameter	Specification
Model	20G1ANC205JN0NNNNN
Frame	Frame 6
Height	665.5 mm
Width	308.0 mm
Depth	346.4 mm
Height	26.20 in
Width	12.13 in
Depth	13.64 in
Approximate Frame Weight	38.6 kg
Approximate Weight in lb	85 lb
Enclosure	IP20/IP00, NEMA/UL Open Type
Cooling	Forced Air
Mounting Orientation	Vertical
Mounting Hardware	Frame 6 mounting hardware

The standard PowerFlex 755 Frame 6 mechanical envelope is approximately 665.5 × 308 × 346.4 mm, with an approximate open-type frame weight of 38.6 kg. Actual supplied weight can vary depending on the exact drive configuration, options, packaging, and accessories.

For cabinet fabrication, the actual mechanical drawing associated with the supplied drive should be used rather than relying only on nominal catalog dimensions.

Adequate clearance should also be provided around the cooling air path. The drive uses forced-air cooling, so cabinet layout should prevent recirculation of hot exhaust air.

---

6. Enclosure and Installation Characteristics

The 20G1ANC205JN0NNNNN is specified as IP20/IP00, NEMA/UL Open Type.

This type of construction is intended for installation inside an appropriate electrical enclosure or control cabinet when the surrounding environment requires additional protection.

The drive itself should not be treated as a sealed outdoor or washdown enclosure.

The cabinet should provide sufficient protection from dust, conductive contamination, moisture, corrosive gases, and accidental contact with energized components.

Because this is a relatively high-power 205 A drive, cabinet thermal design is particularly important.

Forced-air cooling requires an airflow path through the drive. The cabinet designer should account for drive heat dissipation, ambient temperature, fan airflow, cabinet ventilation, and the heat produced by other equipment installed in the same enclosure.

---

7. Dynamic Braking

The catalog configuration of 20G1ANC205JN0NNNNN has no internal dynamic-braking transistor.

This is an important selection point.

Dynamic braking is normally used when the motor needs controlled deceleration and the regenerated energy from the motor must be dissipated through a braking resistor.

Since this particular configuration does not include an internal dynamic-braking transistor, applications requiring substantial regenerative braking should be reviewed carefully during system design.

For loads with high inertia, rapid stopping, frequent deceleration, vertical movement, hoists, elevators, centrifuges, unwinders, or other regenerative loads, the braking strategy should be evaluated separately.

Do not assume that the drive’s standard configuration provides a complete braking solution simply because the drive can perform controlled deceleration.

---

8. Embedded EtherNet/IP

One of the major features of the 20G1ANC205JN0NNNNN is its embedded EtherNet/IP communication capability.

This allows the drive to be integrated into an industrial control architecture without requiring a separate basic communication interface for standard Ethernet-based drive control.

Typical network functions include:

• Drive command and status exchange.
• Speed reference transmission.
• Monitoring of drive operating parameters.
• Fault and alarm information.
• Parameter access.
• Production data collection.
• Drive diagnostics.
• Integration with programmable control systems.
• Remote start/stop and speed control.
• Network-based commissioning and troubleshooting.

For machines with several drives, embedded network communication can significantly simplify system wiring compared with extensive hardwired analog and digital control connections.

---

9. Product Introduction

The Allen-Bradley 20G1ANC205JN0NNNNN is a high-power air-cooled variable-frequency drive from the PowerFlex 755 series.

It is designed for three-phase 400 VAC industrial power systems and provides 205 A of output current.

Its 110 kW Normal Duty rating makes it suitable for large motor applications where variable speed and controlled motor operation are required.

The drive can regulate motor speed according to a process reference rather than operating the motor continuously at line frequency.

This can reduce unnecessary mechanical stress and, in suitable variable-torque applications, reduce energy consumption by matching motor speed to the actual process requirement.

The drive is also suitable for applications where controlled acceleration and deceleration are more important than simply turning a motor on and off.

The Frame 6 construction provides a larger physical platform suitable for this current range, while forced-air cooling supports continuous operation at high electrical loading.

The embedded EtherNet/IP interface makes the drive suitable for modern networked machine architectures.

---

10. Main Product Advantages

10.1 High Current Capacity

The 205 A output rating allows the drive to control relatively large industrial motors.

This makes the model suitable for applications where smaller compact drives would not provide sufficient current capacity.

The 110 kW Normal Duty rating also provides a practical selection point for large pumps, fans, conveyors, compressors, and process machines.

---

10.2 Large Motor Control Capability

The PowerFlex 755 platform is designed for industrial motor control rather than simple low-power speed adjustment.

It can be used in systems where motor speed, acceleration, deceleration, torque, and process behavior need to be controlled from a central automation system.

---

10.3 Embedded Industrial Networking

Embedded EtherNet/IP reduces the need for additional communication hardware for basic network integration.

This is particularly useful in systems containing multiple drives.

Drive status, command information, speed references, fault information, and selected operating parameters can be exchanged through the industrial network.

---

10.4 Forced-Air Cooling

The Frame 6 drive uses forced-air cooling.

For high-power applications, forced-air cooling provides a practical way to manage the heat generated by the power electronics.

Correct cabinet ventilation and airflow management remain essential.

---

10.5 AC Input with Precharge

The AC input with precharge configuration provides a standard architecture for industrial AC power applications.

The precharge stage manages the initial DC bus charging process when the drive is energized.

---

10.6 Filtered Configuration

The specified model includes a filtered configuration with the CM jumper installed.

This can be useful in installations where conducted electromagnetic interference and common-mode behavior need to be considered as part of the overall system design.

The final grounding and EMC arrangement should always match the actual installation and motor-cable configuration.

---

10.7 Open-Type Cabinet Integration

The IP20/IP00 open construction makes the drive suitable for integration into larger control cabinets and electrical rooms.

This allows the system designer to combine the drive with circuit protection, disconnects, contactors where required, PLC equipment, terminal blocks, communication equipment, and other control components.

---

11. Typical Product Applications

11.1 Pumps

The drive can be used for industrial pump systems where flow or pressure needs to be controlled by adjusting motor speed.

Typical applications include process pumps, water circulation systems, cooling-water systems, industrial transfer pumps, and general fluid-handling equipment.

For centrifugal pump applications, variable-speed operation can reduce throttling losses and allow the pump to follow process demand more closely.

---

11.2 Fans and Blowers

Fans and blowers are common variable-torque applications.

The drive can regulate fan speed according to airflow, temperature, pressure, or another process variable.

This allows the motor to operate at a speed appropriate to the actual demand instead of remaining at full speed continuously.

---

11.3 Conveyors

The 205 A current capacity makes the drive suitable for larger conveyor systems.

Applications can include material handling, bulk material transport, production lines, packaging systems, warehouse equipment, and heavy industrial conveyors.

Controlled acceleration can reduce mechanical shock to belts, gearboxes, couplings, and transported materials.

---

11.4 Compressors

The drive can be used in selected compressor applications where adjustable motor speed is required.

Compressor applications require careful attention to motor control mode, acceleration requirements, minimum operating speed, process control, and the compressor manufacturer’s requirements.

---

11.5 Mixers

Industrial mixers may require substantial starting torque and controlled speed.

The Heavy Duty rating should be considered when the application involves high starting torque, high-viscosity materials, or frequent load changes.

---

11.6 Material Handling Equipment

The PowerFlex 755 platform can be used for larger material-handling machinery such as conveyors, feeders, processing lines, transfer systems, and other equipment requiring coordinated motor speed control.

---

11.7 HVAC and Cooling Systems

Large industrial ventilation and cooling equipment can use variable-frequency drives to adjust fan and pump speed.

This is particularly useful when system demand changes during production.

---

11.8 Water and Wastewater Systems

Large water-treatment and wastewater installations often use variable-speed pumps and blowers.

The drive can provide controlled motor operation and network communication for integration into a centralized process control system.

---

11.9 Process Machinery

The drive can be used on process machines where motor speed needs to follow a production setpoint.

Examples include rollers, mixers, material feeders, production conveyors, and other continuous-process machinery.

---

12. Application Selection Considerations

The correct selection should not be based only on the motor horsepower.

The motor nameplate current should be compared with the drive’s rated output current.

For this model, the main electrical reference is 205 A, with 110 kW Normal Duty and 90 kW Heavy Duty ratings.

If the motor has a high service factor, unusual overload requirements, frequent acceleration, high inertia, or high starting torque, the Heavy Duty rating should be considered.

The actual application cycle is often more important than the motor’s nominal kW rating.

For example, a conveyor that starts frequently under load may impose a greater thermal and current demand than a large fan operating at a nearly constant speed.

---

15. Five Same-Brand Reference Models

The following Allen-Bradley models are useful reference products from other drive families. They are not direct substitutes for the 20G1ANC205JN0NNNNN because their power range, physical size, control functions, and intended applications are different.

They are included as same-brand comparison points rather than as direct replacement recommendations.

Model	Series	Voltage	Current	Power Rating	Frame	Typical Application Range
25B-D030N114	PowerFlex 525	380–480 VAC, 3 PH	30 A	20 HP ND / 15 HP HD	D	Small and medium machines

17. Advantages in Large Industrial Systems

High Power Density

A 205 A output rating allows a single drive to control a relatively large motor without dividing the application into multiple smaller drives.

This can simplify the main drive architecture when the application is based around one large motor.

Network Integration

Embedded EtherNet/IP allows the drive to become part of a larger control network.

This is useful when the motor needs to be controlled by a centralized automation system rather than by local pushbuttons alone.

Controlled Acceleration

Adjustable acceleration profiles can reduce mechanical shock.

This is especially useful on conveyors, fans with large rotating inertia, pumps, and machines with gearboxes.

Controlled Deceleration

The drive can manage deceleration rather than simply removing motor power.

The absence of an internal dynamic-braking transistor in this specific configuration means the braking requirements of high-inertia applications must be reviewed separately.

Process Control

The drive can be used as part of a process-control loop where speed is adjusted according to pressure, flow, temperature, tension, production rate, or another process variable.

Cabinet Integration

The open-type construction is suitable for integration into larger electrical cabinets.

This allows the drive to be installed alongside protection devices, control equipment, terminal blocks, communication components, and other industrial electrical hardware.

Regenerative load	Requires detailed engineering	Standard configuration has no internal dynamic-braking transistor

---

19. Installation Considerations

Before installing the drive, verify that the incoming supply is compatible with the 400 VAC three-phase configuration.

The motor should be checked against the drive’s current rating rather than simply comparing horsepower or kW.

For a 205 A drive, the incoming feeder, circuit protection, disconnecting means, power conductors, grounding system, and cabinet bus arrangement must all be designed for the actual installation.

The forced-air cooling system must have an unobstructed airflow path.

Heat generated by the drive should be included in the cabinet thermal calculation.

The drive should be mounted vertically unless the installation documentation for the specific configuration allows another orientation.

The motor cable routing should be planned with EMC considerations in mind.

Control wiring and power wiring should be arranged to reduce unnecessary electromagnetic coupling.

The CM jumper configuration should be evaluated against the grounding system and EMC requirements of the installation.

---

20. Maintenance Considerations

The cooling system should be inspected periodically.

Dust accumulation on ventilation paths and cooling components can reduce airflow and increase operating temperature.

Fans are mechanical components and should be treated as maintenance items in applications with high operating hours.

Electrical connections should be inspected according to the maintenance schedule used for the machine.

The drive should be checked for fault history, abnormal temperature, unusual fan noise, and other signs of deteriorating operating conditions.

Because the drive is installed in an industrial cabinet, the condition of cabinet filters, ventilation openings, cooling fans, and surrounding equipment can directly affect drive life.

23. Overall Product Description

The Allen-Bradley 20G1ANC205JN0NNNNN PowerFlex 755 is a high-power, three-phase AC drive designed for industrial motor control in the 400 VAC class.

With a 205 A output rating, 110 kW Normal Duty capability, 90 kW Heavy Duty capability, and Frame 6 construction, it is intended for applications substantially larger than compact machine drives.

Its forced-air cooling system, open-type enclosure, AC input with precharge, filtered configuration, CM jumper installation, and embedded EtherNet/IP communication make it suitable for integration into industrial control cabinets and networked automation systems.

The model is particularly well suited to large pumps, fans, blowers, conveyors, material-handling equipment, water-treatment machinery, cooling systems, and process equipment where motor speed needs to be controlled rather than operated continuously at fixed line frequency.

One of the most important characteristics to verify during selection is the absence of an internal dynamic-braking transistor. Applications involving high inertia, rapid stopping, vertical loads, or substantial regenerative energy require a separate braking and energy-management review.

The standard Frame 6 mechanical envelope is approximately 665.5 mm high × 308 mm wide × 346.4 mm deep, with an approximate open-type drive weight of 38.6 kg. These dimensions are suitable for preliminary cabinet planning, while final mechanical drawings should be used for fabrication and installation.

The PowerFlex 755 platform is well suited to large industrial drive systems where the electrical rating, network communication, controlled acceleration and deceleration, process control, and cabinet integration requirements are more demanding than those of compact general-purpose VFDs.

For replacement work, the complete catalog number should always be matched rather than selecting a drive only by voltage and horsepower. Filtering, CM jumper configuration, dynamic braking, HMI configuration, enclosure, input arrangement, and frame size can all affect whether a particular model is a true configuration match.
