6. Electrical Characteristics

The most important electrical characteristics of this model are its 600 V AC three-phase input configuration and 355 A class current rating.

The drive is intended for large AC motor applications where a substantial amount of current is required.

The actual usable motor horsepower should not be determined from the catalog number alone. Motor voltage, motor current, power factor, efficiency, duty cycle, overload requirements and ambient operating conditions all need to be considered.

For a normal-duty application, the continuous motor current should be checked against the applicable drive rating.

For applications involving frequent overloads, high starting torque or rapid acceleration, the drive should be evaluated using the actual operating profile rather than simply matching the motor’s nominal horsepower.


7. Duty Classification

The model is intended around a normal-duty industrial configuration.

Duty classification is important because a drive may be capable of handling a certain continuous current but have different permissible overload characteristics depending on the operating mode.

A conveyor carrying a heavy load, for example, can require significantly more torque during acceleration than a fan operating at a stable speed.

Similarly, a mixer can have a changing load as material enters or leaves the mixing chamber.

The following parameters should therefore be considered together:

Selection parameter Importance
Continuous motor current Determines basic drive capacity
Starting torque Important for high-inertia machinery
Acceleration time Affects thermal and current loading
Deceleration time Important for high-inertia loads
Overload requirement Determines required drive rating
Motor voltage Must correspond to the drive configuration
Ambient temperature Affects available thermal capacity
Altitude Can affect cooling performance
Motor cable length Can influence installation and filtering requirements
Feedback requirement Determines control configuration

8. Dimensions and Weight

The 20G1F3E355LNDNNNNN is a large industrial drive rather than a compact wall-mounted VFD.

For product planning, a large-frame cabinet arrangement can be treated as approximately:

Physical parameter Approximate value
Height 2453 mm
Width 1200 mm
Depth 600–800 mm
Weight 1246 kg
Height Approx. 96.6 in
Width Approx. 47.2 in
Depth Approx. 23.6–31.5 in
Weight Approx. 2748 lb

These figures should be treated as reference dimensions for the large-frame cabinet arrangement, not as guaranteed shipping dimensions for every possible catalog configuration.

Additional cabinets, input protection, reactors, filters, disconnect equipment and other options can increase both the footprint and total weight.

The approximately 1246 kg reference weight is especially important for transportation and installation planning.


9. Product Introduction

The 20G1F3E355LNDNNNNN is designed to provide controlled operation of high-power AC motors.

A conventional fixed-frequency motor connection provides relatively limited control over motor speed. A variable-frequency drive changes the electrical output supplied to the motor so that operating speed and torque can be managed according to the machine’s requirements.

This allows a large motor to start gradually, operate at different speeds and stop according to a controlled profile.

The drive can also exchange information with an automation system, making it possible to coordinate motor operation with sensors, controllers, production equipment and other drives.

For a large industrial machine, this makes the drive an important part of the complete control architecture rather than simply a device for changing motor frequency.


10. Main Product Features

10.1 High-Power Motor Control

The 355 A class rating provides substantial current capacity for large industrial motors.

This makes the drive suitable for equipment that is beyond the practical range of smaller general-purpose drives.

Large conveyors, pumps, fans and process machinery can all require this type of high-current motor-control equipment.


10.2 Variable-Speed Operation

The drive can control the operating speed of the motor.

The motor does not need to remain at one fixed operating speed throughout the entire production cycle.

This can be particularly useful when machine output needs to change according to production conditions.


10.3 Controlled Acceleration

Large motors can produce significant mechanical stress when started directly.

The drive can increase motor speed gradually according to a programmed acceleration profile.

This can help reduce mechanical shock to:

  • Shafts
  • Couplings
  • Gearboxes
  • Belts
  • Chains
  • Conveyor systems
  • Pumps
  • Fans
  • Mechanical transmission components

10.4 Controlled Deceleration

The same principle applies during stopping.

A controlled deceleration profile can reduce abrupt changes in mechanical load.

This is particularly useful for large rotating equipment with high inertia.


10.5 Torque Control

Large industrial machinery often needs controlled torque rather than simple speed regulation.

The PowerFlex 755 platform is designed for applications where motor torque needs to be controlled as part of the machine process.

This is useful for:

  • Conveyors
  • Mixers
  • Material-handling equipment
  • Process machinery
  • Large mechanical systems

10.6 Feedback Capability

The drive can be configured with compatible feedback equipment for applications requiring more precise motor regulation.

Feedback can be useful for applications involving:

  • Precise speed control
  • Synchronization
  • Tension control
  • High-inertia loads
  • Specialized process machinery

The actual feedback hardware should be selected according to the motor and application requirements.


11. Product Advantages

High Current Capacity

The 355 A class rating makes the model suitable for large motor applications.

It can provide considerably more electrical capacity than compact drive products.

This makes it suitable for high-power production equipment and process systems.


High-Performance Motor Control

The PowerFlex 755 platform is designed for advanced motor-control applications.

It can provide controlled acceleration, deceleration, speed regulation and torque management.

This gives engineers more flexibility when designing machines with demanding mechanical characteristics.


Suitable for Industrial Automation

The drive can operate as part of a larger industrial automation system.

A controller can provide a speed reference while monitoring drive status, current, speed, warnings and faults.

This allows the motor-control system to become part of the production-control architecture.


Flexible Application

The drive can be used with many different types of industrial equipment.

Typical applications include:

  • Pumps
  • Fans
  • Conveyors
  • Compressors
  • Mixers
  • Process equipment
  • Material-handling machinery
  • Large production machinery

Large Industrial Construction

The large-frame architecture provides the physical space required for high-power electrical components.

This makes the product appropriate for large industrial electrical rooms, machine rooms and engineered control systems.


12. Typical Applications

Conveyor Systems

Large conveyors frequently require high starting torque.

A conveyor may already be loaded when the motor starts, which can produce significant mechanical demand.

The drive can accelerate the motor gradually, helping the conveyor reach operating speed in a controlled manner.

The operating speed can also be changed according to production requirements.


Large Pumps

Industrial pumps can require motors with substantial power.

The drive allows pump speed to be adjusted according to the process requirement.

This can be useful for:

  • Water treatment
  • Industrial circulation
  • Cooling systems
  • Process fluid systems
  • Large water-transfer equipment

Large Fans

Industrial fans can operate at different speeds depending on the required airflow.

The drive can adjust the motor speed according to the ventilation or process requirement.

Typical applications include:

  • Industrial ventilation
  • Cooling
  • Exhaust systems
  • Process air handling
  • Large ventilation equipment

Compressors

Large compressors can have high motor starting requirements.

Controlled acceleration can make the starting process more manageable and can allow the compressor motor to be integrated into a larger control system.


Mixers

Mixers can experience changing loads as material is introduced or processed.

The drive can provide controlled speed and torque to accommodate changes in the mechanical load.


Process Machinery

Large process machines often require coordinated motor operation.

The drive can be integrated with the machine’s controller so that motor speed becomes part of the overall production sequence.


13. Industry Applications

Industry Typical Applications
Manufacturing Large production machinery
Mining Conveyors and material handling
Metals Processing and transport equipment
Paper Process machinery
Chemical processing Pumps, mixers and compressors
Water treatment Large pumps
Utilities Pumps and fans
Cement Conveyors and processing equipment
Building materials Material handling
Food processing Mixers and conveyors
Heavy industry Large motor-driven equipment
Process manufacturing Pumps, fans and compressors

14. Application Advantages

The main practical advantage of using a high-power variable-frequency drive is the ability to match motor operation to the actual mechanical process.

A pump can run at a speed appropriate to the required flow.

A fan can operate according to the required airflow.

A conveyor can accelerate smoothly and run at the speed required by production.

A mixer can use different speeds for different stages of processing.

A compressor can use controlled motor operation as part of the overall process.

This flexibility is one of the main reasons large industrial variable-frequency drives are widely used in automated machinery.

19. Automation Integration

The PowerFlex 755 platform is designed to operate within an industrial automation environment.

A typical installation can include:

  • Programmable controllers
  • Human-machine interfaces
  • Sensors
  • Industrial networks
  • Motor feedback devices
  • Safety equipment
  • Other variable-frequency drives
  • Process instrumentation

The drive can receive operating commands from the automation system and return information about its operating condition.

Typical monitored information can include:

  • Motor speed
  • Output frequency
  • Output current
  • Operating status
  • Fault status
  • Warning status
  • Torque-related information
  • Drive temperature
  • Operating condition

This type of integration is useful when the drive is part of a production line rather than operating as a standalone motor controller.


20. Feedback Applications

Feedback becomes important when the machine requires more precise speed regulation.

A suitable feedback device can provide information about actual motor speed to the drive.

This can be useful for:

  • Precise speed regulation
  • Synchronization
  • Tension control
  • Large conveyors
  • High-inertia machinery
  • Process equipment
  • Specialized industrial motor-control systems

The final feedback configuration depends on the motor and application.


21. Thermal Management

A high-power drive produces a considerable amount of heat during operation.

The air-cooled construction uses forced airflow to remove heat from the power electronics.

The installation therefore needs sufficient ventilation.

Thermal consideration Requirement
Ambient temperature Must remain within the applicable operating range
Airflow Must be sufficient for heat removal
Cooling fans Must remain operational
Air filters Should be kept clean
Cabinet clearance Must allow suitable airflow
Load Higher load increases heat generation
Adjacent equipment Heat from nearby equipment must be considered
Altitude May influence thermal performance
Maintenance Cooling system should be inspected periodically

Thermal management is especially important when the drive is installed in a closed electrical room or cabinet system with several other high-power devices.


22. Installation Requirements

The large physical size of this product means that installation planning should begin before the equipment is delivered.

The approximately 2453 mm height should be checked against the available building access.

The approximately 1200 mm width should also be considered when planning doors, corridors and equipment spacing.

The approximately 1246 kg weight requires suitable transportation and lifting equipment.

Installation item Main consideration
Floor loading Verify that the floor can support the equipment
Transportation Check the entire delivery route
Door opening Verify cabinet dimensions
Lifting Use equipment suitable for the actual weight
Ventilation Provide sufficient airflow
Cable routing Provide adequate space for large power cables
Grounding Provide suitable industrial grounding
Maintenance Provide appropriate service access
Ambient environment Control temperature, dust and moisture
Cabinet arrangement Confirm final configuration before installation

23. Motor Selection

The correct motor should be selected according to the drive’s electrical rating and the actual machine load.

Important motor parameters include:

Motor parameter Why it matters
Rated voltage Must correspond to drive voltage
Full-load current Main parameter for drive sizing
Rated power Helps determine application capacity
Frequency Must correspond to motor operation
Power factor Affects electrical loading
Efficiency Affects input/output relationship
Service factor Important for actual operating conditions
Starting torque Important for heavy loads
Operating speed Determines speed-control requirements
Feedback Determines whether encoder integration is needed

A drive should not be selected simply because its nominal horsepower is close to the motor’s horsepower.

The motor’s rated current and the actual mechanical load are more useful parameters when determining the appropriate drive configuration.


24. Example Application — Conveyor

Consider a large conveyor carrying bulk material.

The conveyor may be empty during startup and heavily loaded during normal operation.

Starting the motor directly can create a large current surge and substantial mechanical shock.

With a variable-frequency drive, the motor can accelerate progressively.

The speed can then be controlled according to production requirements.

If the conveyor needs to stop, the drive can use a controlled deceleration profile.

This can help reduce mechanical stress on the gearbox, coupling, belt and other mechanical components.


25. Example Application — Pump

A large industrial pump may need to operate at different flow levels throughout the day.

Running the motor at full speed at all times may not correspond to the actual process requirement.

The drive allows motor speed to be adjusted.

This makes the drive useful for large pumping applications in industrial water systems, cooling systems and process plants.


26. Example Application — Industrial Fan

A large ventilation fan may operate under different airflow requirements.

During periods of lower demand, the motor speed can be reduced.

During higher demand, the speed can be increased.

The variable-speed drive therefore provides an adjustable interface between the motor and the ventilation process.


27. Example Application — Mixer

Large industrial mixers often experience changes in mechanical load.

Different stages of the process may require different speeds.

The drive can provide controlled acceleration and adjustable operating speed while allowing the motor-control system to communicate with the overall process controller.

31. Final Product Description

The 20G1F3E355LNDNNNNN is a high-power PowerFlex 755 AC drive designed for large industrial motor-control applications.

Its 600 V AC three-phase configuration and 355 A class rating place it in the high-power category, making it suitable for substantial industrial motors and machinery.

The product is particularly useful when the machine requires more than simple motor starting and stopping. Variable-speed control allows the motor to operate according to the actual production requirement, while controlled acceleration and deceleration can improve the mechanical behavior of the equipment.

The drive can also provide torque control and can be configured with suitable feedback equipment for applications requiring improved speed regulation.

Typical applications include large conveyors, industrial pumps, large fans, compressors, mixers, process machinery and heavy material-handling equipment.

The physical characteristics are equally important. A representative large-frame installation is approximately 2453 mm high, 1200 mm wide and 600–800 mm deep, with a reference weight of approximately 1246 kg. The final size and weight can change according to the complete cabinet and option configuration.

When selecting this model, the motor’s actual nameplate voltage and current should be considered first. The machine’s duty cycle, overload requirements, acceleration and deceleration characteristics, operating environment, feedback requirements, communication architecture and installation conditions should then be evaluated.

The 20G1F3E355LNDNNNNN is therefore best suited to projects requiring a substantial industrial AC drive with high-current capability, controlled motor operation and integration into a larger automated machine or process system.
