---

10. Frame 7 Construction

The 20F1ANE289AA0NNNNN uses a Frame 7 construction.

This large mechanical frame provides space for high-current power components, cooling equipment, power terminals and internal electrical components.

The Frame 7 construction is appropriate for high-power industrial applications.

The physical design provides room for:

• High-current connections
• Power switching components
• Cooling airflow
• Internal bus structures
• Control electronics
• Protection components
• Power terminals

Because of its size, cabinet engineering becomes an important part of the installation.

---

11. Dimensions and Weight

The approximate physical dimensions are:

881.5 mm height

430 mm width

349.6 mm depth

The approximate weight is:

72.6 kg

Mechanical Parameter	Specification
Model	20F1ANE289AA0NNNNN
Frame	7
Height	Approx. 881.5 mm
Width	Approx. 430 mm
Depth	Approx. 349.6 mm
Weight	Approx. 72.6 kg
Enclosure	Open Type
Cooling	Forced Air
Mounting	Cabinet / Panel
Mechanical Category	Large Industrial Drive

These dimensions are suitable for preliminary cabinet planning.

Final installation work should allow additional space around the drive for wiring, ventilation, maintenance and safe service access.

The approximate 72.6 kg weight also means the mounting structure should be designed to support the drive securely.

---

12. Open-Type Enclosure

The drive is supplied in an open-type configuration.

This type of drive is intended to be incorporated into a suitable industrial enclosure.

The enclosure should provide appropriate protection against:

• Dust
• Moisture
• Condensation
• Oil
• Conductive contamination
• Corrosive materials
• Mechanical impact
• Excessive temperature

The enclosure should also provide adequate ventilation.

For a 289 A Frame 7 drive, heat management is especially important.

---

13. Forced-Air Cooling

The 20F1ANE289AA0NNNNN uses forced-air cooling.

Large power electronic devices generate heat during operation.

The cooling system moves air through the drive to remove heat from the power section.

Cooling performance depends on:

• Ambient temperature
• Airflow
• Cabinet ventilation
• Fan operation
• Air cleanliness
• Filter condition
• Cabinet layout
• Drive loading

Dust and debris can restrict airflow.

For this reason, cooling fans and airflow passages should be included in the maintenance program.

---

14. EMC Filtering

The model includes an EMC filter.

Variable-frequency drives use high-speed semiconductor switching.

This switching can generate high-frequency electrical noise.

The EMC filtering arrangement helps control conducted electromagnetic interference.

However, good EMC performance also depends on:

• Grounding
• Cabinet bonding
• Motor cable selection
• Cable shielding
• Cable routing
• Control cable separation
• Proper termination

The EMC filter should therefore be considered as one part of the complete electrical installation.

---

15. CM Jumper Removed

One of the important configuration details of the model is:

CM Jumper = Removed

This is an important distinction when comparing the AA configuration with other PowerFlex 753 configurations.

For example, the closely related JN configuration uses an installed CM jumper.

The electrical system and grounding architecture should therefore be considered before selecting a replacement or alternative configuration.

---

16. AA Configuration and Dynamic Braking

The AA configuration is particularly important because it includes an:

Internal Dynamic-Braking Transistor

The dynamic-braking transistor allows the drive to work with an appropriate external braking resistor arrangement when the application needs to dissipate regenerative energy.

This makes the AA configuration more suitable for applications involving:

• High-inertia loads
• Rapid deceleration
• Frequent stopping
• Large rotating equipment
• Conveyor systems
• Mixers
• Material-handling equipment
• Applications with significant regenerative energy

The braking resistor and overall braking arrangement must still be properly engineered for the application.

---

17. Why Dynamic Braking Matters

When a large motor decelerates, the rotating motor and machine contain stored mechanical energy.

During deceleration, this energy can return toward the drive.

If the application requires rapid stopping, the regenerative energy can become significant.

Dynamic braking provides a method for dissipating this energy through a suitable braking resistor.

A simplified sequence is:

Motor Running

↓

Deceleration Command

↓

Motor Generates Regenerative Energy

↓

DC Bus Voltage Rises

↓

Dynamic-Braking Transistor Activates

↓

Braking Resistor Dissipates Energy

↓

Controlled Deceleration

This makes the AA configuration particularly useful for demanding deceleration applications.

---

18. Braking Advantages

Compared with a configuration without an internal dynamic-braking transistor, the AA version offers a more convenient foundation for dynamic-braking applications.

Potential advantages include:

• Faster controlled stopping
• Better handling of regenerative energy
• Greater flexibility for high-inertia machines
• Better suitability for frequent deceleration
• Improved application flexibility
• Easier integration of a braking resistor

The correct braking resistor must still be selected according to:

• Motor power
• Motor speed
• Load inertia
• Deceleration time
• Stop frequency
• Regenerative energy
• Duty cycle

---

19. Embedded I/O

The drive includes embedded I/O.

This provides drive-level interface capabilities for machine control.

Embedded I/O can be used for functions such as:

• Start commands
• Stop commands
• Speed references
• Status signals
• Fault signals
• Interlocks
• Process feedback
• External sensors

This makes the drive easier to integrate into an industrial control system.

---

20. Blank / No HIM

The model is configured as:

Blank (No HIM)

HIM refers to the Human Interface Module.

A no-HIM configuration is suitable for systems where the drive is controlled primarily through:

• PLC systems
• HMI systems
• Centralized control panels
• Supervisory control systems
• Industrial communication networks

This can create a cleaner machine-panel design when local drive operation is not required.

---

21. AC Input With Precharge

The drive uses:

AC Input with Precharge

and:

No DC Terminals

The precharge circuit manages the initial charging of the DC-link capacitors.

A simplified sequence is:

AC Supply

↓

Precharge

↓

DC-Link Charging

↓

DC-Link Stabilization

↓

Normal Drive Operation

This is especially important in high-power drive systems because the DC-link capacitors represent a substantial electrical load during startup.

---

22. Product Introduction

The 20F1ANE289AA0NNNNN is a high-power industrial variable-frequency drive intended to control large AC motors.

Its primary purpose is to provide adjustable motor speed, controlled acceleration and controlled deceleration.

A variable-frequency drive allows the motor operating frequency to be adjusted.

This creates a flexible operating system:

Start

↓

Controlled Acceleration

↓

Operating Speed

↓

Speed Adjustment

↓

Controlled Deceleration

↓

Stop

This approach is useful for large industrial machinery where fixed-speed operation is inefficient or mechanically undesirable.

↓

Mixing Speed

↓

Process Operation

↓

Controlled Deceleration

↓

Stop

Dynamic braking can be useful where rapid stopping is required.

---

31. Agitator Applications

Industrial agitators may require different operating speeds during different process stages.

Applications can include:

The high current rating makes the drive suitable for large material-handling machinery.

Potential applications include:

• Bulk-material systems
• Large transfer equipment
• Heavy conveyors
• Processing lines
• Production logistics
• Large rotating material-handling systems

The dynamic-braking capability is especially valuable where stopping performance is important.

---

The 289 A continuous output rating provides substantial capacity for large industrial motors.

This is the main reason to select this model instead of smaller PowerFlex configurations.

---

36.2 300 HP Normal-Duty Rating

The 300 HP normal-duty rating makes the drive particularly suitable for large variable-torque equipment.

Large pumps, fans and blowers are typical examples.

---

The 600 VAC class makes the drive suitable for high-power industrial electrical systems.

---

36.5 Frame 7 High-Power Platform

The Frame 7 construction provides a mechanical platform for large current and power requirements.

---

36.6 Internal Dynamic-Braking Transistor

This is one of the most important advantages of the AA configuration.

The internal DB transistor provides a foundation for dynamic-braking applications.

---

36.7 EMC Filter

The integrated EMC filter helps control conducted electrical noise.

---

36.8 Embedded I/O

Embedded I/O simplifies integration with industrial control systems.

---

36.9 No-HIM Configuration

The blank/no-HIM arrangement is useful for centralized automation systems.

---

36.10 Flexible Application Range

The drive can support a broad range of large industrial motor applications.

---

37. Dynamic Braking as a Major Advantage

The dynamic-braking capability differentiates this model from configurations that do not include an internal DB transistor.

For a large rotating machine, the ability to handle regenerative energy can be extremely important.

This is particularly true for:

• Heavy conveyors
• Large mixers
• High-inertia fans
• Large rotating machines
• Machines requiring rapid stopping
• Systems with frequent acceleration and deceleration

The braking system should be designed around the actual regenerative energy of the application.

---

38. Energy-Saving Potential

Variable-speed control can reduce energy consumption in suitable variable-torque applications.

For example:

High Process Demand

↓

Higher Motor Speed

↓

Higher Pump/Fan Output

and:

Low Process Demand

↓

Lower Motor Speed

↓

Lower Output

↓

Potentially Lower Energy Consumption

This is particularly useful for:

• Centrifugal pumps
• Fans
• Blowers
• Cooling systems
• Air-handling systems

Actual energy savings depend on the machine and process.

---

39. Controlled Acceleration

Large motors can create significant mechanical stress during startup.

The drive allows acceleration to be controlled.

A simplified acceleration sequence is:

0 Hz

↓

10 Hz

↓

20 Hz

↓

30 Hz

↓

40 Hz

↓

Operating Frequency

The exact acceleration profile depends on:

• Motor characteristics
• Load inertia
• Machine requirements
• Acceleration time
• Torque requirements

Controlled acceleration can reduce mechanical shock.

---

40. Controlled Deceleration

Controlled deceleration is especially important for large rotating systems.

The motor and machine contain stored mechanical energy while operating.

During deceleration, that energy can return toward the drive.

The AA configuration’s internal dynamic-braking transistor provides a useful means of controlling this regenerative energy when paired with an appropriate braking resistor.

This can be advantageous for applications requiring:

• Fast stopping
• Frequent stopping
• Controlled deceleration
• High-inertia load management

---

41. Braking Application Evaluation

Braking Factor	Importance
Motor Horsepower	High
Motor Speed	High
Motor Current	High
Load Inertia	Very High
Motor Inertia	Very High
Deceleration Time	Very High
Stop Frequency	High
Regenerative Energy	Very High
Braking Resistor	Application Dependent
Dynamic-Braking Duty Cycle	Very High
Mechanical Brake	Application Dependent

The internal DB transistor does not eliminate the need for proper braking-system design.

The braking resistor must be appropriately selected for the expected regenerative energy and duty cycle.

---

42. Cabinet Design

The drive is approximately:

881.5 mm × 430 mm × 349.6 mm

with an approximate weight of:

72.6 kg

The cabinet should therefore be designed around the actual drive dimensions rather than treating it as a compact drive.

Adequate space should be provided for:

• Power cables
• Motor cables
• Control cables
• Airflow
• Heat dissipation
• Service access
• Cable bending radius
• Adjacent equipment
• Maintenance

---

43. Thermal Management

Thermal management is one of the most important design considerations for a high-power drive.

The cabinet should provide adequate airflow.

The installer should consider:

• Ambient temperature

• Cooling-fan performance
• Cabinet ventilation
• Filter condition
• Heat generated by other equipment
• Air circulation

Poor cabinet ventilation can increase internal temperature.

This can negatively affect the operating environment of the drive.

---

44. Electrical Installation Considerations

The installation should consider:

• 600 VAC supply
• Three-phase input
• Input protection
• Grounding
• Motor cable sizing
• Control wiring
• EMC practices
• Cabinet ventilation
• Motor current
• Motor insulation
• Braking requirements
• Environmental conditions
• Available fault current

The 289 A drive should be installed as part of a complete electrical system designed for the appropriate current and fault conditions.

---

45. Motor Selection

Motor Parameter	Importance
Motor Voltage	Critical
Motor Full-Load Current	Critical
Motor Horsepower	Important
Motor Frequency	Important

Motor Torque	Critical
Duty Cycle	Critical
Motor Inertia	Important
Load Inertia	Very Important
Acceleration Time	Important
Deceleration Time	Critical
Braking Requirement	Critical
Ambient Temperature	Important
Installation Altitude	Important

A 300 HP motor should not be selected solely because the drive carries a 300 HP normal-duty rating.

The motor’s actual current and operating profile must be checked.

---

46. Automation Integration

The drive can operate as the high-power motor-control stage in an industrial automation system.

A typical architecture is:

Sensors

↓

PLC / Controller

↓

Speed Reference

↓

20F1ANE289AA0NNNNN

↓

Large AC Motor

↓

Machine

↓

Process

↓

Feedback

Embedded I/O supports direct drive-level control and status functions.

The no-HIM configuration is well suited to installations where the main operator interface is located elsewhere.

---

47. Typical Industrial Control Architecture

The product can be integrated into systems involving:

• PLC control
• HMI operation
• Motor status monitoring
• Process feedback
• Start/stop interlocking
• Speed references
• Alarm handling
• Fault management
• Industrial networking

This allows the drive to function as part of a larger automated process rather than operating as an isolated motor controller.

---

48. Preventive Maintenance

A large Frame 7 drive should be included in a structured maintenance program.

Maintenance Area	Recommended Action
Cooling Fans	Check operation
Airflow	Keep unobstructed
Cabinet Filters	Clean or replace
Power Connections	Inspect
Motor Connections	Inspect
Grounding	Inspect
Control Wiring	Check
Cabinet Interior	Keep clean
Temperature	Monitor
Fault History	Review
Mounting	Inspect
Ventilation	Verify
EMC Connections	Inspect
Braking Resistor	Inspect when installed
Braking Wiring	Inspect when installed

The cooling system and braking components are particularly important for this configuration.

---

49. Cooling System Inspection

The cooling fans should be checked for:

• Abnormal noise
• Reduced airflow
• Mechanical damage
• Dust accumulation
• Intermittent operation

Air passages should remain unobstructed.

The cabinet should also prevent excessive heat from accumulating around the drive.

---

50. Braking System Inspection

If a braking resistor is installed, the maintenance program should include:

• Resistor condition
• Wiring condition
• Terminal condition
• Signs of overheating
• Mounting condition
• Ventilation
• Cable insulation
• Abnormal temperature

The braking resistor can generate substantial heat during braking events.

Its physical installation should therefore provide adequate thermal clearance.

---
