4. Electrical Rating

The most important characteristic of the 20G11BC1K4AN0NNNNN is its very high current capability.

The drive is rated at approximately 1,465 A output current, placing it in the high-power industrial-drive category rather than the general small-machine VFD category.

This current capacity makes the model suitable for large motors used in heavy industrial processes.

Typical equipment in this power range can include large water pumps, high-capacity fans, blowers, conveyors, process machinery, mining equipment and other large rotating loads.

5. Power Ratings

The rating should always be considered together with the application’s duty requirement.

Duty	Power Rating
Light Duty	Approximately 850 kW
Normal Duty	800 kW
Heavy Duty	630 kW

The 800 kW Normal Duty rating is the most commonly referenced rating for continuous industrial applications.

The 630 kW Heavy Duty rating should be considered when the motor is subjected to more demanding torque or overload conditions.

The approximately 850 kW Light Duty figure represents the higher power capability available when the load profile is less demanding.

6. 400 V AC Three-Phase Design

The drive is designed for the 400 V AC three-phase industrial voltage class.

The broader operating voltage range is generally associated with the 380–480 V class used in industrial installations, while the catalog rating for this specific configuration is 400 V AC.

A typical system arrangement can be represented as:

Three-Phase AC Supply

↓

PowerFlex 755 Drive

↓

Large AC Motor

↓

Pump / Fan / Conveyor / Process Equipment

The drive converts and regulates the electrical power delivered to the motor, allowing the motor’s speed and torque characteristics to be coordinated with the production process.

7. Frame 9 Construction

The 20G11BC1K4AN0NNNNN is a Frame 9 PowerFlex 755 configuration.

Frame 9 is used for high-power drive applications and is physically much larger than compact industrial VFDs.

The drive architecture is designed to accommodate high-current power components, cooling equipment, control electronics and high-power electrical connections.

For this reason, installation planning is an important part of selecting this model.

The equipment should be considered as a large industrial electrical assembly rather than simply as a conventional wall-mounted VFD.

8. Enclosure and Protection

The model uses an IP20 / Type 1 enclosure arrangement and a 600 mm deep MCC-style configuration.

This configuration is intended for an appropriate industrial electrical environment.

It should not be interpreted as a weatherproof outdoor enclosure.

The electrical room or MCC environment should therefore provide suitable protection against:

• Direct water.
• Rain.
• Excessive dust.
• Condensation.
• Corrosive contaminants.
• Uncontrolled outdoor exposure.
• Excessive temperature.

9. Dimensions

The catalog configuration identifies a 600 mm cabinet depth.

The 600 mm depth is particularly important when the drive is installed inside an MCC lineup or electrical room with limited rear or front service space.

Mechanical Parameter	Specification
Model	20G11BC1K4AN0NNNNN
Frame	Frame 9
Enclosure	IP20 / Type 1
Cabinet style	MCC style
Depth	600 mm
Overall height	Configuration-dependent
Overall width	Configuration-dependent
Cooling	Air cooled
Installation type	Industrial electrical room / MCC lineup
Final dimensional reference	Applicable mechanical drawing

The exact height and width should be taken from the mechanical drawing for the final configuration.

This is preferable to using a generic dimension because large Frame 9 equipment can vary depending on the exact packaged arrangement.

10. Weight

Large Frame 9 PowerFlex 755 equipment is heavy industrial machinery.

A comparable direct-replacement Frame 9 configuration is listed at approximately 2,800 lb, equivalent to about 1,270 kg. For engineering purposes, the target AN0 configuration should therefore be treated as being in the approximately 1,270 kg class rather than as a small-drive installation.

Weight Parameter	Approximate Value
Model	20G11BC1K4AN0NNNNN
Equipment type	Frame 9 high-power AC drive
Approximate weight (kg)	1,270 kg class
Approximate metric tons	1.27 t
Transportation	Heavy equipment
Floor loading	Must be checked
Lifting equipment	Required
Final shipping weight	Confirm against actual equipment documentation

The 1,270 kg figure should be treated as a planning value.

For final crane selection, transportation documents, floor-loading calculations and lifting procedures, the actual supplied equipment documentation should always take precedence.

11. No Local HIM Configuration

The AN0 configuration is listed with a blank / no HIM operator-interface arrangement.

This means the drive is intended to be integrated into a control architecture where local operator-interface hardware is not necessarily required.

This configuration can be attractive for systems that use:

• PLC control.
• HMI control.
• SCADA control.
• Industrial Ethernet.
• Centralized maintenance systems.

Instead of placing a display directly on the drive, the application can rely on external control and communication equipment.

12. Embedded EtherNet/IP

The PowerFlex 755 platform is designed for integration into industrial automation systems, and the 755 family provides embedded EtherNet/IP capability.

This is useful when the drive needs to exchange information with a PLC or supervisory system.

Typical information can include:

• Start and stop commands.
• Speed references.
• Drive status.
• Output frequency.
• Motor current.
• Fault information.
• Alarm information.
• Operating status.
• Diagnostic information.

13. EMC Filter

The model is configured with an EMC filter.

EMC management is particularly important in large variable-frequency-drive installations because the high-speed switching used by the inverter can generate high-frequency electrical noise.

The filter is only one part of the complete EMC solution.

The overall installation should also consider:

• Motor-cable shielding.
• Grounding.
• Cabinet bonding.
• Cable routing.
• Control-cable separation.
• Communication-cable routing.
• Motor-cable length.
• Proper termination.

14. CM Jumper Removed

The AN0 configuration is associated with the EMC-filtered arrangement and CM jumper removed.

This is an important catalog-level configuration detail.

The common-mode capacitor arrangement can influence how the drive interacts with the facility’s grounding system.

The correct configuration should therefore be selected according to the electrical distribution system and installation requirements.

This is one reason why replacing a drive solely by matching current and voltage is not always sufficient.

15. Dynamic Braking

The 20G11BC1K4AN0NNNNN is listed with no dynamic-braking transistor.

This can be perfectly suitable for many large industrial applications where rapid deceleration is not required.

For example, a large centrifugal pump can often be allowed to decelerate over a controlled period.

A large fan may also operate without regenerative or dynamic braking.

However, applications with large inertia or frequent rapid stopping should be evaluated carefully.

16. Product Introduction

The 20G11BC1K4AN0NNNNN is essentially a high-power motor-control platform for industrial equipment.

Its main job is to control the speed and electrical behavior of a large AC motor.

Instead of operating a motor directly from a fixed-frequency power supply, the drive controls the electrical output supplied to the motor.

This gives the machine designer much more control over the process.

A pump can run at a lower speed when less flow is required.

A fan can reduce speed when ventilation demand decreases.

A conveyor can accelerate smoothly instead of receiving a sudden mechanical shock.

A process machine can maintain a more stable operating point.

17. Why Variable-Speed Control Matters

In many industrial systems, the motor does not need to operate at full speed continuously.

Operating a motor at a fixed speed and controlling the process using mechanical restrictions can result in unnecessary energy consumption.

Variable-speed control provides another approach.

The drive can adjust motor speed according to the process demand.

This is particularly useful for centrifugal pumps and fans, where the relationship between speed and flow or pressure can make speed control much more efficient than continuously operating at maximum speed.

18. Typical Applications

Application	Suitability
Large water pumps	Excellent
Wastewater pumps	Excellent
Cooling-water pumps	Excellent
Large centrifugal fans	Excellent
Industrial blowers	Excellent
Mining conveyors	Excellent

30. Advantage — High Current Capacity

The 1,465 A current rating is the key characteristic of this model.

This makes it suitable for motors that are much larger than those served by compact VFDs.

The model can therefore be used for major plant equipment rather than only individual machine tools or small production machines.

31. Advantage — 800 kW Normal Duty

The 800 kW Normal Duty rating gives the drive a substantial operating range.

This makes it suitable for many large continuously running motors.

Typical examples include:

• Large pumps.
• Fans.
• Blowers.
• Conveyors.
• Process equipment.

32. Advantage — 630 kW Heavy Duty

The 630 kW Heavy Duty rating is important when the application requires more demanding motor operation.

Heavy Duty selection can become relevant when the motor experiences:

• Higher torque.
• Greater acceleration requirements.
• Higher overload demand.
• More severe production cycles.
• Greater mechanical inertia.

33. Advantage — Air Cooling

The air-cooled construction avoids the need for a liquid-cooling system.

This can simplify plant design.

However, the electrical room still needs adequate heat removal.

Large drives produce substantial heat, so ventilation and temperature control should be considered during the initial project design.

34. Advantage — Industrial Automation Integration

The PowerFlex 755 platform is designed to operate as part of a broader automation system.

A typical architecture can include:

PLC

↓

EtherNet/IP

↓

PowerFlex 755

↓

Large Motor

↓

Process Equipment

This allows the drive to become part of the overall control strategy rather than operating as an isolated speed controller.

35. Advantage — No Local HIM for Centralized Systems

The absence of a local HIM can actually be an advantage in some installations.

For example, a large pump station may have all operator functions handled through an HMI in the control room.

In such an installation, a blank local interface can provide a clean cabinet arrangement while avoiding unnecessary local operator hardware.

36. Advantage — Standardization

The PowerFlex 755 family contains a broad range of current and power ratings.

This allows an industrial facility to standardize around one drive platform.

For example:

• Small motors can use lower PowerFlex ratings.
• Medium motors can use intermediate Frame 7 or Frame 8 configurations.
• Large motors can use Frame 9.
• Very large motors can use larger Frame 9 or Frame 10 configurations.

This can simplify engineering, spare-parts management and maintenance training.

53. Current-Based Selection

For high-power 400 V applications, the PowerFlex 755 family provides several nearby rating classes.

Rating Class	Approximate Current	Approximate Normal Duty
BC910	910 A	500 kW
BC1K0	1,045 A	560 kW
BC1K1	~1,090 A	630 kW class
BC1K2	1,175 A	710 kW
BC1K4	1,465 A	800 kW
BC1K5	1,480 A	850 kW
BC1K6	1,590 A	900 kW

The rating progression is useful when selecting the drive according to motor current and duty requirements.

54. Motor Selection Considerations

A drive should not be selected from motor kW alone.

The following motor information should be checked:

Motor Parameter	Importance
Motor voltage	Must match the drive voltage class
Motor current	Primary drive-sizing factor
Motor power	General capacity reference
Motor frequency	Defines base operating condition
Motor speed	Determines operating range
Motor torque	Determines application suitability
Starting torque	Important for demanding loads
Overload	Important for duty selection
Acceleration time	Affects current demand
Deceleration time	Determines braking requirements
Duty cycle	Affects thermal loading
Cable length	Influences installation and EMC
Motor insulation	Important for inverter-fed motors

55. Why Motor Current Matters More Than kW Alone

Two motors with the same kW rating can have different current requirements.

The actual drive selection should therefore be based on the motor nameplate and the application’s operating conditions.

For the 20G11BC1K4AN0NNNNN, the 1,465 A rating is the critical electrical reference.

The motor should not simply be described as an “800 kW motor” and matched automatically.

The motor voltage, current, duty and overload characteristics must also be checked.

56. Installation Considerations

A drive of this size requires detailed installation planning.

The electrical system should consider:

• Incoming transformer capacity.
• Short-circuit current.
• Protective-device coordination.
• Cable sizing.
• Grounding.
• EMC.
• Motor-cable routing.
• Ventilation.
• Heat dissipation.
• Service clearance.
• Transportation.
• Lifting.
• Floor loading.

57. Heat Management

The drive is air cooled.

Large industrial drives generate significant heat, so electrical-room ventilation should be designed accordingly.

Maintenance teams should periodically inspect:

• Cooling fans.
• Air passages.
• Filters where applicable.
• Cabinet temperature.
• Dust accumulation.
• Ventilation paths.
• Signs of overheating.

58. Electrical Room Planning

The physical installation should provide enough space for:

• Front access.
• Cable installation.
• Maintenance.
• Component replacement.
• Cooling airflow.
• Electrical isolation.
• Safe working procedures.

The 600 mm depth should be included in the initial cabinet-layout design.

The actual height and width should be taken from the final mechanical drawing rather than estimated.

59. Transportation and Lifting

With an approximate weight in the 1,270 kg class, this equipment should be treated as heavy industrial machinery.

The project should consider:

• Factory delivery route.
• Door dimensions.
• Floor strength.
• Forklift capacity.
• Crane capacity.
• Lifting points.
• Temporary storage.
• Final installation position.
• Maintenance access.

The transportation plan should be prepared before equipment delivery.

60. Maintenance

A practical maintenance program can include:

• Cooling-fan inspection.
• Electrical-terminal inspection.
• Cabinet cleaning.
• Grounding inspection.
• Motor-cable inspection.
• Control-wiring inspection.
• Communication checks.
• Fault-history review.
• Parameter backup.
• Temperature monitoring.
• Visual inspection for overheating.

61. Parameter Backup

Parameter backup is particularly important for large industrial drives.

The final configuration should be saved after commissioning.

The backup may include:

• Motor nameplate information.
• Speed limits.
• Acceleration time.
• Deceleration time.
• Control mode.
• Start-command source.
• Speed-reference source.
• I/O configuration.
• Network configuration.
• Fault configuration.
• Process-control parameters.

62. Commissioning Procedure

A practical commissioning process can be divided into several stages.

Step 1 — Verify the Catalog Number

Confirm:

20G11BC1K4AN0NNNNN

The catalog number contains important information about the drive rating and configuration.

Step 2 — Verify Incoming Power

Confirm:

• Voltage.
• Phase.
• Frequency.
• Grounding.
• Protective devices.

Step 3 — Verify Motor Nameplate

Record:

• Voltage.
• Current.
• Frequency.
• Power.
• Speed.
• Power factor.
• Efficiency.

Step 4 — Configure the Drive

Enter the correct motor and application parameters.

Do not assume that settings from another motor are automatically appropriate.

Step 5 — Check Motor Rotation

Verify rotation before connecting the motor to the complete mechanical process.

Step 6 — Perform a Low-Speed Test

Check:

• Motor current.
• Direction.
• Vibration.
• Noise.
• Drive status.
• Mechanical response.

Step 7 — Gradually Increase Speed

Monitor:

• Current.
• Temperature.
• Motor behavior.
• Mechanical response.
• Process performance.

Step 8 — Test Automation Communication

Verify communication between:

• PLC.
• HMI.
• Drive.
• Network.
• Supervisory system.

63. Typical Automation Architecture

A typical large industrial system could be arranged as:

SCADA

↓

HMI

↓

PLC

↓

EtherNet/IP

↓

PowerFlex 755

↓

20G11BC1K4AN0NNNNN

↓

400 V AC Motor

↓

Pump / Fan / Conveyor / Process Machine

This architecture is especially suitable for plants where the drive does not require a local HIM.

64. AN0 Configuration and Centralized Control

The absence of a local HIM makes the AN0 configuration suitable for centralized systems.

For example, consider a large water-treatment plant.

The pump may be located in a remote pumping room.

The control-room operator can use the plant HMI to:

• Start the pump.
• Stop the pump.
• Set speed.
• Monitor current.
• Monitor frequency.
• View faults.
• Monitor process pressure.

The drive can perform the motor-control work while the PLC and HMI handle the operator-facing functions.

65. Advantages in Large Pump Systems

For pump applications, the major advantages include:

• Controlled acceleration.
• Variable-speed operation.
• Process-flow control.
• Pressure control.
• Reduced mechanical shock.
• Centralized monitoring.
• Fault reporting.
• Network integration.
• Easier coordination with other pumps.

66. Advantages in Large Fan Systems

For large fans, the drive can provide:

• Controlled acceleration.
• Variable airflow.
• Process-pressure control.
• Centralized speed control.
• Reduced unnecessary operation at full speed.
• Integration with plant automation.

This is especially useful for industrial ventilation and process exhaust systems.

67. Advantages in Conveyor Systems

For conveyors, the major benefits can include:

• Smooth acceleration.
• Controlled deceleration.
• Reduced belt shock.
• Better speed coordination.
• Centralized control.
• Fault monitoring.
• Process synchronization.

68. Advantages in Mining

Mining equipment can place demanding requirements on motor-control equipment.

The drive can be used in systems where:

• Motor power is high.
• Starting conditions are demanding.
• Process speed must be controlled.
• Centralized monitoring is required.
• Large rotating machinery must be coordinated with other plant equipment.

69. Important Difference Between AN0 and JN0

The target model is:

20G11BC1K4AN0NNNNN

The direct replacement is:

20G11BC1K4JN0NNNNN

The two models share the same major electrical rating class:

• 400 V AC.
• 1,465 A.
• 800 kW Normal Duty.
• 630 kW Heavy Duty.
• Frame 9.
• Air cooled.
• 600 mm deep MCC style.

The significant configuration change is the CM jumper arrangement. The AN0 configuration is associated with the CM jumper removed, while the JN0 replacement is listed with the CM jumper installed.

70. Recommended Replacement Strategy

If the original drive is being replaced, the 20G11BC1K4JN0NNNNN should be the first model evaluated because it is the listed direct replacement.

However, replacement should not be performed by catalog-number comparison alone.

The project should also check:

• Motor data.
• Application duty.
• Existing parameter settings.
• Communication architecture.
• EMC configuration.
• Grounding arrangement.
• Mechanical dimensions.
• Cable connections.
• Control wiring.
• Firmware compatibility.
• Safety configuration.

75. Final Product Assessment

The 20G11BC1K4AN0NNNNN is a very large industrial AC drive designed for demanding motor-control applications.

Its 1,465 A current rating and 800 kW Normal Duty capacity place it among the high-power PowerFlex 755 configurations.

The combination of 400 V AC, Frame 9, air cooling, IP20 / Type 1 protection and 600 mm MCC-style depth makes it particularly appropriate for large industrial electrical rooms and MCC-based installations.

The drive is especially well suited to large pumps, fans, blowers, conveyors, mining equipment, cement equipment, water-treatment systems and other process machinery requiring controlled speed and high motor current.

Its AN0 configuration is useful in centralized automation systems because it does not include a local HIM.

This arrangement makes sense where the PLC, HMI or SCADA system is expected to provide the operator interface.

One of the most important points when dealing with this exact catalog number is its lifecycle status.

The original 20G11BC1K4AN0NNNNN was discontinued on June 30, 2024, and the listed direct replacement is 20G11BC1K4JN0NNNNN.

Therefore, for a new installation, the replacement model should normally be evaluated first rather than treating the original AN0 configuration as a current-production selection.

From an electrical standpoint, the direct replacement remains in the same major rating class, with 1,465 A output, 800 kW Normal Duty, 630 kW Heavy Duty, 400 V AC, Frame 9 and 600 mm depth.

The main catalog-level difference is the CM-jumper configuration.

For projects where a smaller drive is acceptable, the 20G11BC1K2 class provides approximately 1,175 A and 710 kW Normal Duty.

For projects requiring more capacity, the 20G11BC1K5 class provides approximately 1,480 A and 850 kW Normal Duty.

For a completely different application scale, the PowerFlex 753 and PowerFlex 525 families provide smaller alternatives.

The PowerFlex 753 example listed above is rated at 456 A / 250 kW Normal Duty, while the PowerFlex 525 example is only 30 A / 15 kW Normal Duty.

The most important engineering point is that the drive should be selected according to motor current, duty cycle, torque requirement, acceleration, deceleration, environmental conditions and installation configuration, not simply according to the motor’s kW value.

In summary, the 20G11BC1K4AN0NNNNN can be described as a 400 V AC, three-phase, approximately 1,465 A, Frame 9, air-cooled PowerFlex 755 industrial AC drive with approximately 850 kW Light Duty, 800 kW Normal Duty and 630 kW Heavy Duty capability, IP20 / Type 1 protection, 600 mm MCC-style depth, EMC filtering, AC input with precharge, no dynamic-braking transistor, no local HIM and embedded EtherNet/IP capability.

For a replacement project, the 20G11BC1K4JN0NNNNN is the primary model to evaluate because it is the listed direct replacement for the original catalog number.
