20G1F3C302LNDNNNNN — Detailed Product Information, Specifications, Applications and Related Models

1. Product Overview

The 20G1F3C302LNDNNNNN is a high-performance industrial AC variable-frequency drive from the PowerFlex 755 series.

This particular configuration is designed for 400 VAC three-phase systems and has a 302 A normal-duty current rating. Its corresponding normal-duty power rating is approximately 160 kW, while the heavy-duty rating is approximately 132 kW.

The configuration uses an Active Front End (AFE) regenerative input, which makes it different from a conventional non-regenerative AC drive. This architecture is especially useful in machinery where energy can flow back from the motor into the drive during deceleration or overhauling conditions.

The catalog configuration is associated with a Frame 7 drive platform. The 302 A / 400 V combination is also associated with a 160 kW normal-duty and 132 kW heavy-duty rating within this frame class.

The model is therefore well suited to industrial machinery requiring substantial motor power, controlled acceleration and deceleration, variable-speed operation and, where applicable, regenerative energy handling.

3. Detailed Electrical Specifications

The 302 A rating is one of the key identifying characteristics of this model.

At 400 VAC, the drive is rated for approximately 160 kW normal duty. For applications with more demanding overload requirements, the heavy-duty classification is approximately 132 kW.

The distinction between normal duty and heavy duty is important when selecting a drive. The motor’s actual load profile, overload duration, starting requirements and acceleration requirements should be considered rather than selecting the drive based solely on the motor’s nominal kW rating.

4. Product Series

PowerFlex 755 Series

The 20G1F3C302LNDNNNNN belongs to the PowerFlex 755 series.

This series is designed for industrial applications where a higher level of motor control, flexibility and system integration is required.

The series supports a broad range of motor powers and electrical configurations. It is commonly associated with applications involving:

• Industrial production machinery
• Conveyors
• Pumps
• Fans
• Compressors
• Mixers
• Material-handling systems
• Process equipment
• High-inertia machinery
• Variable-speed production systems

The 20G1F3C302LNDNNNNN sits in the medium-to-high industrial power range of the series, with a 160 kW normal-duty rating.

---

5. Product Introduction

The primary function of the 20G1F3C302LNDNNNNN is to control a three-phase AC motor by regulating the frequency and voltage supplied to the motor.

A fixed-frequency motor connected directly to an AC supply generally operates around a fixed speed determined by supply frequency and motor characteristics.

A variable-frequency drive provides a much wider range of control.

The drive can adjust motor speed according to process requirements, allowing machinery to operate at different speeds rather than being limited to one fixed operating point.

This makes the drive useful for industrial processes in which production speed, flow, pressure, torque or mechanical movement must be controlled.

The drive can also provide controlled acceleration and deceleration.

For a 160 kW motor, this is particularly valuable because direct starting and stopping can create substantial electrical and mechanical stresses.

---

6. Active Front End Regenerative Configuration

A major feature of the 20G1F3C302LNDNNNNN is its AFE regenerative input.

During normal motor operation, electrical energy flows from the supply through the drive and into the motor.

During regenerative operation, the direction of energy flow can change.

For example, when a high-inertia load decelerates, the rotating machinery can drive the motor. The motor then operates as a generator and sends electrical energy back toward the drive.

An AFE system can manage this regenerated energy and return it toward the AC supply under appropriate operating conditions.

This is particularly useful in applications where regenerative operation occurs repeatedly.

Typical examples include:

• Cranes
• Hoists
• Large conveyors
• High-inertia machines
• Test equipment
• Unwinding equipment
• Lowering mechanisms
• Repetitive acceleration/deceleration machinery

---

7. Product Advantages

7.1 160 kW Normal-Duty Capacity

The drive provides a normal-duty rating of approximately 160 kW.

This makes it suitable for a substantial range of industrial motors.

It is considerably larger than compact machine-level drives and is intended for applications where the motor and mechanical system require a more capable industrial drive platform.

---

7.2 302 A Current Capacity

The 302 A normal-duty current rating provides sufficient capacity for large three-phase industrial motors within the corresponding voltage and duty requirements.

Current rating is often more important than horsepower alone when selecting a VFD.

The drive should therefore be selected according to the actual motor nameplate current and application duty.

---

7.3 Regenerative Operation

The AFE regenerative configuration allows the drive to handle regenerative energy in applications where the motor repeatedly enters generating operation.

This can be advantageous compared with systems that rely exclusively on resistor-based braking.

Potential advantages include:

• Improved regenerative energy management
• Reduced dependence on braking resistors
• Less heat generated by resistor braking
• Better suitability for high-inertia machinery
• Improved suitability for repeated deceleration
• Better suitability for four-quadrant applications

---

7.4 Controlled Acceleration

Large motors can draw substantial current during direct starting.

The drive allows acceleration to be controlled using a programmed ramp.

This can reduce mechanical shock and provide smoother machine operation.

This is particularly useful for:

• Conveyors
• Pumps
• Fans
• Compressors
• Mixers
• Material-handling systems

---

7.5 Controlled Deceleration

The drive also provides programmable deceleration.

Controlled stopping can be useful when a machine contains a large rotating mass or when the process requires a predictable stopping time.

In regenerative applications, deceleration also provides the opportunity for the drive to manage the energy generated by the motor.

---

7.6 Advanced Motor Control

The PowerFlex 755 architecture supports several motor-control approaches.

Depending on the complete configuration, applications can use control methods such as:

• V/Hz
• Sensorless vector
• Flux vector
• Encoder-based control
• Induction motor control
• Permanent-magnet motor control in applicable configurations

The appropriate control mode depends on the motor and application.

---

8. Physical Specifications

The model is associated with Frame 7.

For the standard Frame 7 configuration, commonly associated physical dimensions are approximately:

• Height: 881.5 mm
• Width: 430 mm
• Depth: 349.6 mm
• Weight: approximately 82 kg

These values correspond to a Frame 7, 400 V, 302 A drive configuration with the associated physical construction.

Because catalog suffixes can represent different enclosure and factory configurations, the exact installed 20G1F3C302LNDNNNNN assembly should still be checked against its mechanical drawing before using these figures for cabinet layout, transport or lifting calculations.

The 82 kg figure should be regarded as an approximate Frame 7 drive weight rather than an unconditional shipping weight for every possible packaged configuration.

Additional cabinet sections, disconnect equipment, input/output components or other factory-installed options can change the final equipment weight.

---

9. Dimensions and Installation

The physical dimensions of a drive are important when planning a control cabinet or electrical room.

For the Frame 7 configuration associated with the 302 A / 400 V rating, the approximate basic drive envelope is:

When designing the installation, the dimensions of the drive itself should not be treated as the complete cabinet requirement.

Additional space may be required for:

• Incoming power cables
• Motor cables
• Grounding conductors
• Control wiring
• Communication cables
• Ventilation
• Airflow
• Maintenance access
• Door clearance
• Cable bending radius
• Protective devices
• Disconnect equipment

For this reason, an engineering drawing should always be used for the final installation layout.

---

10. Typical Applications

10.1 Conveyors

The 302 A drive is suitable for large conveyor motors.

Variable-speed operation allows the conveyor speed to be matched to production requirements.

Controlled acceleration can reduce sudden torque loading on:

• Gearboxes
• Couplings
• Conveyor belts
• Shafts
• Rollers

For conveyors that frequently decelerate or operate with overhauling loads, regenerative operation can also be useful.

---

10.2 Pumps

Large industrial pumps often benefit from variable-speed operation.

Instead of operating continuously at maximum motor speed, the drive can adjust speed according to process requirements.

Typical applications include:

• Water circulation
• Cooling systems
• Process water
• Industrial utilities
• Water treatment
• Manufacturing systems

---

10.3 Fans and Blowers

Large fans and blowers can consume substantial amounts of electrical power.

Variable-speed operation allows airflow to be adjusted according to process demand.

The drive can also provide controlled starting, reducing the mechanical and electrical impact of motor startup.

---

10.4 Compressors

Compressors may require controlled acceleration and substantial torque.

The drive can provide adjustable-speed operation and controlled motor performance.

The actual compressor application must be evaluated carefully because compressor torque characteristics can vary significantly between machine types.

---

10.5 Cranes and Hoists

The regenerative capability makes this type of drive particularly relevant to applications involving repeated acceleration, deceleration and lowering.

During lowering or overhauling operation, the motor may become regenerative.

The AFE architecture provides an appropriate drive technology for such operating conditions.

---

10.6 Mixers

Large mixers can require substantial starting torque.

Variable-speed operation can be used to control the mixing process and adjust the motor operating point.

---

10.7 High-Inertia Machinery

Large rotating systems can store substantial mechanical energy.

When such machinery decelerates, energy can be returned through the motor.

A regenerative drive configuration can therefore be useful for high-inertia machinery with frequent stopping and starting.

25. Product Advantages in Practical Industrial Use

---

26. Important Selection Considerations

When selecting or replacing this drive, the following parameters should be checked carefully.

Motor Current

The actual motor full-load current should be compared with the drive’s normal-duty and heavy-duty current ratings.

The 302 A rating should not be interpreted as a universal motor size because the required current depends on motor voltage, power factor, efficiency, duty and application conditions.

---

Motor Power

The normal-duty rating is approximately 160 kW.

The heavy-duty classification is approximately 132 kW.

The appropriate rating depends on the actual application.

---

Voltage

The requested configuration is based on a 400 VAC three-phase system.

A 480 VAC model with the same current rating should not be assumed to be electrically interchangeable.

---

Regeneration

The AFE regenerative architecture should be confirmed as a genuine application requirement.

If the machinery does not produce significant regenerative energy, another drive architecture may sometimes be more appropriate.

---

Physical Installation

The approximate Frame 7 physical envelope is:

881.5 mm × 430 mm × 349.6 mm

with an approximate basic drive weight of:

82 kg

Additional cabinet equipment can increase the overall installation footprint and weight.

• 302 A rating
• High-power industrial construction
• Specific enclosure and option configuration

Two PowerFlex 755 drives can have very similar catalog numbers while differing in input arrangement, enclosure, braking equipment, HIM arrangement or other factory options.

Therefore, a similar-looking model should not be regarded as an automatic replacement.

---

29. Suitable Industries

The product can be applied across a broad range of industrial sectors.

The actual suitability depends on the motor, load profile, environmental conditions and electrical installation.

31. Conclusion

The 20G1F3C302LNDNNNNN is a substantial industrial AC drive designed around a 400 VAC three-phase supply, 302 A normal-duty output rating and approximately 160 kW normal-duty capacity.

Its AFE regenerative input is one of the most important characteristics of the configuration. It allows the drive to be considered for machinery where regenerative energy is an important part of normal operation, particularly equipment with frequent acceleration and deceleration or overhauling loads.

The Frame 7 construction gives the drive a physical size appropriate for larger industrial installations. A representative Frame 7 configuration is approximately 881.5 mm high, 430 mm wide and 349.6 mm deep, with an approximate basic weight of 82 kg.

The drive is particularly applicable to large conveyors, pumps, fans, blowers, compressors, cranes, hoists, mixers and other industrial machinery requiring adjustable motor speed and controlled acceleration/deceleration.

When selecting a replacement, the most important parameters to match are 400 VAC input, 302 A current rating, 160 kW normal-duty rating, 132 kW heavy-duty rating, AFE regenerative architecture, Frame 7 construction and the complete option configuration.

For a new installation, motor nameplate current and the actual load profile should be used as the primary sizing references. The final mechanical dimensions and weight should also be confirmed against the exact equipment configuration before transportation, cabinet fabrication or installation.
