4. Electrical Rating
The most important electrical characteristic of the 20G1ALC750AN0NNNNN is its 750 A current rating.
This places it above the 650 A configuration in the same family and makes it appropriate for larger motors or applications requiring greater current capacity.
The drive has three principal power-duty ratings:
| Duty Classification | Rated Power |
|---|---|
| Light Duty | 450 kW |
| Normal Duty | 400 kW |
| Heavy Duty | 315 kW |
| Current Rating | 750 A |
The 450 kW light-duty rating is particularly significant because it gives this configuration additional capacity for applications with relatively moderate overload requirements.
The 400 kW normal-duty rating makes it suitable for many large continuous industrial loads.
The 315 kW heavy-duty rating should be considered when the application requires higher overload capability or more demanding torque characteristics.
5. 400 VAC Three-Phase Power
The drive is designed for a 400 VAC three-phase industrial power system.
This voltage class is common in many industrial plants and process facilities.
The three-phase input supplies the drive’s power-conversion section, which then generates controlled variable-frequency output power for the motor.
The drive can regulate motor speed according to the requirements of the mechanical system and process.
This makes it possible to operate a large motor at the speed actually required by the application instead of continuously operating at fixed line frequency.
6. 750 A Current Capacity
The 750 A current rating is particularly useful for applications where motor current is too high for smaller drive configurations.
High current capacity can be important during:
- Motor acceleration
- High-load operation
- Heavy process conditions
- High-inertia starting
- Torque-demand changes
- Continuous industrial operation
The drive should nevertheless be selected using the motor’s actual full-load current and application duty rather than simply matching the motor’s nominal kW value.
7. Light-Duty, Normal-Duty and Heavy-Duty Operation
Large industrial drives are commonly selected according to the mechanical load profile.
For this model:
| Duty | Power Rating | Typical Load Character |
|---|---|---|
| Light Duty | 450 kW | Relatively moderate overload demand |
| Normal Duty | 400 kW | General industrial continuous loads |
| Heavy Duty | 315 kW | Higher torque / overload requirements |
A large fan or pump may operate under relatively smooth conditions.
A conveyor or heavy process machine may require greater torque during acceleration and therefore need to be evaluated using the heavy-duty rating.
This distinction is important because two motors with similar nameplate power can impose very different demands on the drive.
8. AC Input with Precharge
The 20G1ALC750AN0NNNNN uses an AC input with precharge configuration.
Precharge is important in high-power drives because the internal DC-link capacitors require controlled charging when the drive is first energized.
The precharge arrangement helps manage the initial charging current and forms an important part of the high-power input architecture.
9. No DC Terminals
This configuration does not provide conventional external DC terminals.
It should therefore not automatically be selected for systems requiring a shared external DC bus.
Where multiple drives are expected to exchange DC-bus energy, or where regenerative power must be handled through a dedicated DC architecture, a suitable drive configuration should be selected specifically for that purpose.
10. Embedded EtherNet/IP
The drive includes embedded EtherNet/IP communication.
This allows the drive to operate as part of a larger industrial automation network.
Typical information that can be exchanged includes:
- Start and stop commands
- Speed reference
- Actual speed
- Output frequency
- Motor current
- Drive status
- Alarm status
- Fault information
- Diagnostic information
- Control commands
- Process feedback
This can reduce the amount of traditional hardwired control wiring required in a large plant.
It also allows the drive to communicate with higher-level automation equipment and supervisory systems.
11. Blank / No HIM Configuration
The AN0 configuration is supplied as a blank / no HIM arrangement.
This is an important difference compared with configurations that include a local operator interface.
A no-HIM configuration can be useful when the drive is intended to be controlled through a PLC, HMI, network, or centralized engineering system.
It also avoids installing a local operator keypad when local manual adjustment is not required.
For a large plant with centralized automation, this can result in a cleaner and more standardized operator architecture.
12. CM Jumper Removed
The model uses a CM jumper removed configuration.
The CM jumper configuration is related to the drive’s common-mode / grounding arrangement and should be considered as part of the overall electrical installation.
This is not simply an interchangeable cosmetic option.
Grounding method, EMC requirements, input power system configuration, and installation environment should all be considered before modifying or replacing this configuration.
13. Filtering and EMC
The drive is specified as a filtered configuration.
High-power variable-frequency drives generate switching components that can influence the surrounding electrical environment.
Proper EMC installation therefore remains important.
The complete installation should consider:
- Motor cable routing
- Cable shielding
- Grounding
- Cabinet bonding
- Separation of power and control wiring
- Network cable routing
- Motor cable length
- Electrical-room grounding
The internal filtering contributes to the overall EMC design, but it should be considered together with correct installation practice.
14. Dynamic Braking
The 20G1ALC750AN0NNNNN does not include an integrated dynamic braking transistor.
This is important for applications involving frequent or rapid deceleration.
When a large motor decelerates, energy can flow back into the drive’s DC bus.
If the mechanical system contains significant inertia, the regenerated energy may become substantial.
Applications requiring rapid stopping should therefore be evaluated for an appropriate braking or regenerative strategy.
15. Cooling System
The drive uses forced-air cooling.
A 750 A high-power drive can produce significant heat during normal operation.
The cooling fans move air through the power section and remove heat generated by the semiconductor devices and other internal components.
The electrical room must therefore provide adequate ventilation.
If several high-power drives are installed in the same room, the combined heat output should be considered when designing the HVAC system.
16. Enclosure and Protection
The drive uses a Type 1 / IP20 enclosure configuration.
This protection level is intended for an appropriate protected electrical installation.
The drive should be installed in a suitable electrical room, MCC area, or other controlled industrial environment.
It is not intended to be directly exposed to outdoor weather, washdown water, or uncontrolled environmental conditions.
Where the process requires a higher environmental protection level, a different enclosure configuration may be more appropriate.
17. Physical Dimensions and Weight
The 20G1ALC750AN0NNNNN is a large industrial electrical assembly.
For general planning, it can be treated as approximately 2450 mm high × 600 mm wide × 800 mm deep, with an approximate equipment weight in the 620–630 kg range.
| Mechanical Parameter | Approximate Specification |
|---|---|
| Model | 20G1ALC750AN0NNNNN |
| Height | Approx. 2450 mm |
| Width | Approx. 600 mm |
| Depth | Approx. 800 mm |
| Weight | Approx. 620–630 kg |
| Frame | Frame 8 |
| Cabinet Style | MCC Style |
| Cabinet Depth | 800 mm |
| Cooling | Forced Air |
| Enclosure | Type 1 / IP20 |
| Installation | Floor / Electrical Room |
Because this is a large and heavy assembly, the final mechanical drawing should be checked before installation.
The actual final shipping dimensions and weight may also differ from the basic equipment configuration because of packaging, accessories, cabinet sections, and installation options.
18. Product Introduction
The 20G1ALC750AN0NNNNN is designed for large industrial motor systems that require high current and high-power variable-speed operation.
Its 750 A output rating provides a substantial amount of electrical capacity.
The drive is particularly suitable for industrial systems where the motor needs controlled acceleration, adjustable speed, process-based control, or communication with a central automation system.
The PowerFlex 755 architecture also allows the drive to become part of a broader plant-control strategy.
Rather than simply converting fixed-frequency power into variable-frequency power, the drive can participate in commands, feedback, diagnostics, and process control.
19. How the Drive Works
The drive receives three-phase AC power from the industrial electrical supply.
The incoming electrical energy is converted inside the drive into a controlled DC-link voltage.
The inverter section then produces a controlled AC output for the motor.
By controlling output frequency and voltage, the drive can control motor speed.
The control system can adjust the motor according to the requirements of the machine or process.
For example, a large pump may require high speed during peak demand and reduced speed during lower-flow conditions.
A variable-frequency drive allows the motor to follow that changing requirement.
20. Main Applications
Large Pump Systems
Large pumps are one of the most common applications for high-power variable-frequency drives.
The drive can adjust motor speed according to the required flow or pressure.
This is useful in water treatment, industrial utilities, process plants, cooling systems, and other fluid-handling applications.
Industrial Fans
Large industrial fans may operate continuously but do not necessarily require maximum speed at all times.
The drive can vary motor speed according to airflow requirements.
This can also reduce unnecessary mechanical loading and provide smoother process control.
Blowers
Large blowers used in industrial processing, ventilation, combustion systems, and air-handling applications can benefit from variable-speed operation.
The 750 A current capability provides the electrical capacity needed for large blower motors.
Conveyors
Large conveyors often require controlled acceleration.
Starting a heavily loaded conveyor directly across the line can produce high mechanical and electrical stress.
A variable-frequency drive can provide controlled acceleration and speed regulation.
Compressors
Large industrial compressors can require substantial motor current and controlled starting.
The drive can provide adjustable speed where the compressor and process design support variable-speed operation.
The exact application should be evaluated according to compressor type and required torque profile.
Process Machinery
The drive can also be used with large mixers, rotating process equipment, feeders, production machines, and other industrial systems.
Material Handling
Large material-handling equipment can use high-power drives for conveyors, feeders, and other motor-driven machinery.
EtherNet/IP communication is particularly useful where multiple drive systems need to operate as part of one coordinated process.
21. Application Comparison
| Application | Typical Requirement | Suitability |
|---|---|---|
| Large Pumps | Variable speed / flow control | Excellent |
| Industrial Fans | Continuous variable-speed operation | Excellent |
| Blowers | High-power speed regulation | Excellent |
| Conveyors | Controlled acceleration and torque | Excellent |
| Compressors | High-power motor control | Suitable |
| Process Machinery | Coordinated motor operation | Excellent |
| Material Handling | High current and controlled acceleration | Excellent |
| Production Equipment | Networked motor control | Excellent |
| Utility Equipment | Continuous-duty operation | Excellent |
| Large Rotating Machinery | High-power variable-speed control | Excellent |
22. Main Product Advantages
High 750 A Current Capacity
The 750 A rating is the central advantage of this configuration.
It provides more current capacity than the 650 A model in the same 400 V family.
This can be useful when the motor current is close to the upper range of a smaller drive.
450 kW Light-Duty Rating
The 450 kW light-duty rating gives this configuration substantial capacity for large industrial equipment with moderate overload requirements.
It provides a useful option for high-power pump, fan, blower, and process applications.
400 kW Normal-Duty Rating
The 400 kW normal-duty rating makes the drive suitable for large continuous industrial applications.
This is particularly relevant for equipment that operates for long periods under relatively stable loading.
315 kW Heavy-Duty Rating
The 315 kW heavy-duty rating provides a lower power ceiling for applications where higher overload performance is required.
This allows the same drive platform to support demanding load profiles without treating all applications as simple constant-load machines.
Embedded EtherNet/IP
The integrated network interface allows the drive to communicate with the larger automation system.
This simplifies centralized monitoring and control and can reduce the amount of discrete wiring required.
No-HIM Configuration
For installations that use centralized control, the no-HIM configuration can be advantageous.
The operator can interact with the drive through a plant HMI, PLC, engineering workstation, or network architecture instead of using a local keypad.
This can also make the electrical-room layout cleaner.
Frame 8 High-Power Architecture
Frame 8 construction provides the physical and electrical scale required for this current class.
It is designed around large industrial installation requirements rather than compact machine-panel installation.
Forced-Air Cooling
Forced-air cooling provides an effective way to manage the thermal load generated by the high-power electronics.
Proper room ventilation remains essential.
Industrial Network Integration
Because the drive can communicate with the automation network, it can participate in coordinated motor-control strategies.
This is particularly valuable in large systems with many motors and process stages.

25. Five Popular Models from the Same Brand
The following models provide a broader view of the same manufacturer’s variable-frequency-drive range.
| Model | Product Family | General Power Class | Typical Application | Main Characteristics |
|---|---|---|---|---|
| 25B-D010N104 | PowerFlex 525 | Low Power | Compact machines | Compact industrial VFD |
| 25C-D010N103 | PowerFlex 527 | Low / Medium | Machine automation | Network-oriented machine drive |

| 20G1ALC750AN0NNNNN | PowerFlex 755 | High Power | Large industrial systems | 400 VAC / 750 A packaged drive |
The PowerFlex 525 and PowerFlex 527 are generally associated with smaller machine applications.
The PowerFlex 753 family extends into medium and larger industrial machinery.
The PowerFlex 755 family is intended for larger and more demanding industrial drive systems.
The 20G1ALC750AN0NNNNN represents a substantially higher power class than the compact-drive examples in the table.
26. Same-Brand Family Comparison
| Product Family | General Application | Typical Installation | Relative Power Class | Main Strength |
|---|---|---|---|---|
| PowerFlex 525 | Compact machines | Panel / machine | Low | Compact control |
| PowerFlex 527 | Machine automation | Panel | Low–Medium | Networked machine control |
| PowerFlex 753 | Industrial machinery | Panel / cabinet | Medium–High | Flexible industrial control |
| PowerFlex 755 | Large industrial systems | MCC / electrical room | High | High-performance and high-power control |
| PowerFlex 755 Packaged | Large plant equipment | Floor / MCC | Very High | Large motor capacity |
27. Installation Requirements
The 20G1ALC750AN0NNNNN should be treated as a major electrical installation.
The approximate 620–630 kg equipment weight means that the floor or supporting structure needs to be suitable for the installed load.
The installation should also provide an appropriate lifting and positioning method.
Because the drive is approximately 800 mm deep, sufficient space should be reserved for cabinet placement and cable access.
The front of the equipment should remain accessible for inspection and maintenance.
28. Ventilation Requirements
The forced-air cooling system requires adequate airflow.
The drive should not be installed where hot exhaust air can immediately return to the cooling intake.
This becomes especially important when multiple high-power drives are installed in the same electrical room.
The total heat produced by all equipment should be considered when selecting ventilation or air-conditioning capacity.
29. Cable Installation
The 750 A rating means that power-cable selection is a major part of the installation design.
Input conductors must be appropriately sized for the electrical system.
Motor cables must also be selected according to motor current, cable length, installation method, temperature, voltage drop, insulation system, and applicable electrical requirements.
Cable routing should also keep high-power conductors appropriately separated from sensitive control and communication cables.
30. Grounding and EMC
Grounding is particularly important in high-power VFD installations.
The drive cabinet, motor, cable shields, and associated control equipment should be incorporated into a properly engineered grounding system.
The filtered configuration can help manage high-frequency electrical noise, but installation technique remains critical.
Incorrect grounding or poorly routed motor cables can result in communication problems, unwanted electrical noise, or interference with other equipment.
31. Maintenance Considerations
Regular maintenance should include inspection of:
- Cooling fans
- Airflow passages
- Electrical connections
- Cabinet condition
- Signs of overheating
- Network connections
- Motor cables
- Grounding connections
- Fault history
- Operating temperatures
- Abnormal sounds
The absence of a local HIM means that maintenance personnel should ensure an appropriate external engineering or diagnostic interface is available when required.
For a centrally controlled plant, this is normally handled through the automation network or maintenance workstation.
32. Typical Industries
| Industry | Typical Equipment |
|---|---|
| Water Treatment | Large pumps |
| Wastewater | Pumping systems |
| Chemical Processing | Pumps and process machinery |
| Manufacturing | Conveyors and rotating machinery |
| Mining | Material handling and conveyors |
| Cement | Fans and process equipment |
| Metals | Large production machinery |
| Utilities | Pumps and fans |
| Infrastructure | Large ventilation systems |
| Material Handling | Conveyors and feeders |
| General Process Industry | Large rotating equipment |
33. Benefits in Centralized Automation
The no-HIM configuration is particularly suitable for systems that rely heavily on centralized automation.
The drive can communicate with a PLC through embedded EtherNet/IP.
The PLC can issue speed commands and receive drive status.
A plant HMI can then present the information to operators.
This approach is common in large automated plants where individual local keypads are not necessary for every motor.
34. Benefits of the No-HIM Configuration
A no-HIM configuration can provide several practical advantages in a centralized-control installation.
First, it eliminates the need for a local keypad when operators are expected to work from a central HMI.
Second, it provides a cleaner front-panel arrangement.
Third, it can reduce the number of local operator interfaces that maintenance personnel need to manage across a large plant.
The trade-off is that technicians need an appropriate external method for local commissioning and troubleshooting when the central control system is unavailable.
35. Why the 750 A Rating Is Important
The difference between 650 A and 750 A may appear relatively small when viewed only as a number.
In a high-power application, however, the additional current capacity can be significant.
It provides more room for large motors and demanding load conditions.
This is especially relevant where the motor full-load current is close to the limit of a smaller drive.
It can also provide more flexibility when the application has significant transient loading.
The drive should still be selected according to the actual motor current and required duty classification.
36. Why the 450 kW Light-Duty Rating Matters
The 450 kW light-duty rating places this configuration above the 400 kW class of the smaller 650 A model.
This makes it particularly attractive for large fans, pumps, and other applications with relatively smooth load characteristics.
For a 400 kW-class motor operating under a suitable duty profile, this configuration provides a substantial amount of drive capacity.
37. Why the 400 kW Normal-Duty Rating Matters
The 400 kW normal-duty rating makes this drive a practical choice for large continuous industrial motors.
It provides a clear selection point for applications where the motor operates under normal industrial loading rather than severe overload conditions.
The actual motor current should always be compared against the drive’s current rating.

The approximate physical size is in the 2450 × 600 × 800 mm class, while the approximate equipment weight is in the 620–630 kg range.
These dimensions and weight make mechanical installation an important part of project planning.
The floor structure, lifting method, cable entry, ventilation, front access, maintenance space, and electrical-room HVAC system should all be considered before installation.
The CM jumper removed configuration and integrated filtering also mean that the electrical installation should be designed with appropriate grounding and EMC practices.
The lack of an integrated dynamic braking transistor should be considered when the drive is intended for high-inertia loads or applications involving frequent rapid deceleration.
The 750 A configuration is especially useful when a 650 A drive does not provide sufficient current capacity but a larger drive is not yet necessary.
Within the same family, the 567 A, 650 A, 770 A, and 710 A / 480 V-class configurations provide useful comparison points depending on motor current, voltage, and duty requirements.
For large pumps, fans, blowers, conveyors, compressors, material-handling equipment, process machinery, and other high-power rotating equipment, this drive provides a combination of high current capacity, network integration, industrial construction, and flexible motor-control capability.
When selecting the drive for a specific project, the most important factors are not only motor kW but also motor full-load current, duty classification, overload requirements, acceleration and deceleration characteristics, braking requirements, ambient conditions, cooling requirements, physical installation space, cable requirements, and the exact catalog-number configuration.
The 20G1ALC750AN0NNNNN is therefore best understood as a large industrial drive intended to serve as a central motor-control component in demanding automation and process systems.
