20G1ANF098JA0NNNNN PowerFlex 755 AC Drive — Product Details, Specifications, Applications and Related Models

The 20G1ANF098JA0NNNNN is a high-power industrial AC variable frequency drive designed for three-phase motor control in demanding industrial applications. It belongs to the PowerFlex 755 series and is configured for 690 V AC systems with a 98 A output-current rating and a 90 kW normal-duty power rating.

The following information is presented as a standalone technical product description, without external links or source references. Where physical specifications can vary with configuration, the values are identified as approximate rather than presented as unnecessarily precise figures.

---

1. Basic Product Information

The 20G1ANF098JA0NNNNN is positioned one capacity level above the 82 A / 75 kW model and below the higher-current 119 A and 142 A configurations in the same 690 V PowerFlex 755 range.

---

2. Product Model

20G1ANF098JA0NNNNN

The complete catalog number is important because the different characters identify electrical and configuration characteristics.

The 098 section is particularly important because it identifies the 98 A current class.

The F portion identifies the 690 V class, which differentiates this model from similar PowerFlex 755 drives designed for 400 V, 480 V, or 600 V systems.

The JA0 portion distinguishes this particular configuration from other versions of the same 98 A / 690 V drive.

For replacement work, the complete catalog number should be matched rather than selecting a drive only according to its kW rating.

---

3. Product Introduction

The 20G1ANF098JA0NNNNN is a high-power variable frequency drive intended to regulate the operation of three-phase AC motors.

In a conventional fixed-frequency motor installation, the motor receives electrical power at a relatively fixed frequency and consequently tends to operate around a fixed operating speed.

A variable frequency drive changes the frequency and voltage supplied to the motor. This allows the motor to operate at different speeds while maintaining controlled acceleration, deceleration, and torque.

For a 90 kW motor, this type of control can be useful in applications where the mechanical load changes during production.

For example, a large pump may not need to run at full speed continuously. A conveyor may need different speeds depending on production conditions. A large fan may need reduced airflow during periods of lower demand.

Instead of using the motor simply as an on/off device, the drive becomes an active part of the machine-control system.

---

4. Main Technical Specifications

---

5. Electrical Rating

The most important electrical specification of this model is its 98 A continuous output rating.

The corresponding normal-duty rating is approximately:

The 90 kW rating makes the model suitable for substantially larger industrial motors than the 75 kW / 82 A version.

The 75 kW heavy-duty rating is also important. A motor application that requires significant starting torque or repeated overload operation should be evaluated using the heavy-duty rating rather than simply looking at the 90 kW normal-duty figure.

---

6. Normal-Duty and Heavy-Duty Operation

A variable frequency drive can have different power ratings depending on the type of load.

The normal-duty rating is generally associated with applications having comparatively moderate overload requirements.

The heavy-duty rating is used for applications that demand greater overload capacity and higher torque during starting or acceleration.

For this model:

This distinction is particularly useful when selecting the drive for machinery such as conveyors, mixers, crushers, material-handling equipment, and other high-torque applications.

---

7. Physical Dimensions and Weight

Physical dimensions are particularly important for this drive because the 90 kW unit is a large industrial power-electronics assembly.

The actual physical weight can vary depending on the final configuration, installed options, packaging, and accessories.

For cabinet construction, lifting arrangements, mounting-hole preparation, or mechanical replacement, the exact mechanical drawing associated with the complete catalog number should be treated as the final dimensional reference.

---

8. Product Applications

8.1 Large Industrial Pumps

One of the most common applications for a drive in this power class is large industrial pumping equipment.

The drive can regulate pump-motor speed according to the required process flow.

Potential applications include:

• Water circulation
• Water treatment
• Industrial cooling
• Process water
• Chemical processing
• Irrigation systems
• Large HVAC systems
• Industrial fluid-transfer systems
• Boiler-related pumping equipment

The ability to vary motor speed can provide much finer process control than simply switching a motor on and off.

---

9. Fans and Blowers

Large fans and blowers are another suitable application area.

A ventilation system does not necessarily require maximum airflow at all times.

The drive can adjust motor speed according to the required airflow.

Typical applications include:

• Industrial ventilation
• Factory exhaust
• Dust extraction
• Furnace ventilation
• Cooling systems
• Large air-handling systems
• Process ventilation
• Industrial blowers

The controlled acceleration provided by a variable frequency drive can also reduce mechanical shock during motor starting.

---

10. Conveyor Systems

The 90 kW capacity is suitable for many large conveyor applications, provided that the motor current and duty requirements remain within the drive rating.

Potential applications include:

• Mining conveyors
• Bulk-material handling
• Aggregate handling
• Production conveyors
• Material-transfer systems
• Heavy industrial conveyors
• Packaging and processing systems

Conveyor applications can benefit from controlled acceleration because sudden motor starting can place considerable stress on belts, couplings, gearboxes, shafts, and mechanical structures.

---

11. Mixers and Agitators

Large mixers and agitators can require considerable starting torque.

A variable frequency drive can provide controlled acceleration rather than applying full electrical power to the motor immediately.

Potential applications include:

• Industrial mixing
• Chemical processing
• Material blending
• Food-processing machinery
• Waste treatment
• Industrial agitation
• Process tanks

For these applications, heavy-duty current requirements should be evaluated carefully.

---

12. Material Handling Equipment

The drive can be applied to material-handling machinery where controlled speed and torque are required.

Examples include:

• Feeders
• Transfer equipment
• Conveyors
• Processing lines
• Bulk-material systems
• Industrial handling machinery

Depending on the machine design, additional braking, feedback, or safety functions may be required.

---

13. Process Machinery

The 20G1ANF098JA0NNNNN can be integrated into larger process machines where a 90 kW-class motor is required.

Typical equipment includes:

• Large rotating machines
• Process pumps
• Fans
• Blowers
• Mixers
• Agitators
• Industrial production equipment
• Material-processing machines

The exact suitability depends on motor characteristics, load profile, speed range, acceleration time, and overload requirements.

---

14. Product Advantages

14.1 High 690 V Operating Class

The 690 V rating makes the drive suitable for large industrial motor systems.

For a given power level, operating at a higher voltage can reduce the current required compared with lower-voltage motor systems.

This can be useful for large motor installations and long industrial cable runs.

---

14.2 90 kW Normal-Duty Capacity

The 90 kW normal-duty rating places this model in a high-power industrial category.

It can handle motor applications considerably larger than compact machine drives.

The 120 HP equivalent rating also makes it convenient for installations where motor specifications are expressed in horsepower rather than kilowatts.

---

14.3 98 A Output Capability

The 98 A output-current class is one of the main reasons to select this model.

Motor selection should always consider actual motor current in addition to motor power.

A 90 kW motor does not necessarily have exactly the same current requirement in every installation because voltage, efficiency, power factor, motor construction, and operating conditions all affect current.

---

14.4 Air-Cooled Construction

The drive uses forced-air cooling.

This allows heat generated by the power electronics to be removed through airflow.

For a 90 kW drive, thermal management is an important part of the installation.

The cabinet should therefore provide appropriate airflow and heat dissipation.

---

14.5 Flexible Motor Control

The PowerFlex 755 architecture supports different motor-control methods.

This allows the drive to be used in relatively straightforward variable-speed applications as well as more demanding applications where improved torque or speed regulation is required.

---

14.6 Industrial System Integration

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

Depending on configuration, control systems can exchange information such as:

• Speed reference
• Motor speed
• Drive status
• Start command
• Stop command
• Current
• Voltage
• Fault information
• Alarm status
• Operating condition

This makes the drive suitable for integrated production systems.

---

14.7 Modular Configuration

The PowerFlex 755 architecture allows different options to be incorporated according to application requirements.

Depending on the selected configuration, applications can use functions related to:

• Communication
• Feedback
• Safety
• I/O
• Operator interface
• Braking
• Motor control

This flexibility is particularly useful when the drive is being incorporated into a machine rather than used as an isolated motor controller.

---

15. Filtering Configuration

The JA0 version is an important distinction within the 20G1ANF098 family.

The model is associated with a filtering configuration in which a jumper arrangement is used.

This means that the exact electrical configuration should be checked before replacing it with another 20G1ANF098 variant.

For example, the following models may look very similar:

They should not automatically be treated as identical replacement units.

The complete model number should be checked against the existing installation.

---

16. Installation Considerations

Because the drive is an open-type, high-power device, it is normally incorporated into an electrical cabinet.

The installation should provide:

• Adequate ventilation
• Appropriate electrical clearances
• Proper grounding
• Correct incoming protection
• Correct motor cable sizing
• Appropriate control wiring
• Suitable environmental protection
• Adequate service access
• Appropriate cable routing
• Proper thermal management

The approximate physical envelope is 665.5 × 308 × 346.4 mm, so cabinet dimensions should provide additional space for airflow, wiring, maintenance, and safe installation.

---

17. Cooling Requirements

A 90 kW-class drive can produce substantial heat during operation.

The cooling arrangement should therefore be considered when designing the cabinet.

Important considerations include:

Poor cabinet ventilation can cause internal temperatures to rise even when the drive itself is correctly sized.

---

18. Control and Automation Applications

The drive can be used in systems where the motor needs to respond to commands from a higher-level control system.

For example, an industrial controller can provide a speed reference while the drive controls the motor.

The drive can then return information about:

• Actual speed
• Output current
• Drive status
• Faults
• Alarms
• Operating condition
• Motor-related information

This type of arrangement is useful in production lines where the motor is only one part of a larger automated process.

---

19. Maintenance Advantages

The PowerFlex 755 platform provides diagnostic information that can assist maintenance personnel.

For an industrial facility, useful information can include:

• Fault history
• Drive operating status
• Current
• Voltage
• Temperature-related conditions
• Alarm conditions
• Communication status
• Motor operating information

This can make troubleshooting more systematic.

Instead of simply determining that a motor has stopped, maintenance personnel can use drive information to investigate whether the problem is related to overload, control commands, electrical conditions, motor operation, communication, or another part of the system.

---

20. Five Recommended Models from the Same PowerFlex 755 Series

The following models are useful comparisons within the same 690 V PowerFlex 755 family.

They cover models below and above the target 98 A / 90 kW unit.

The 20G1ANF082JA0NNNNN is useful when the motor requirement is below the 90 kW level.

The 20G1ANF119JA0NNNNN provides additional current capacity for larger motors.

The 20G1ANF142JA0NNNNN is intended for an even larger power range.

For all of these models, the motor nameplate current should be checked before selecting the drive.

---

29. Final Product Summary

The 20G1ANF098JA0NNNNN is a 90 kW / 120 HP, 98 A, 690 V three-phase PowerFlex 755 AC drive designed for high-power industrial motor control.

Its combination of high-voltage operation, 98 A output capability, 90 kW normal-duty capacity, 75 kW heavy-duty capacity, forced-air cooling, open-type construction, flexible motor-control capability, and industrial system integration makes it suitable for large pumps, fans, blowers, conveyors, mixers, process machinery, and other demanding motor-driven equipment.

The model’s Frame 6 construction gives it a substantial physical footprint, with approximate dimensions of 665.5 × 308 × 346.4 mm and an approximate weight in the 48–50 kg range.

The most important electrical selection parameter is not the 90 kW rating by itself. The motor’s actual rated current should be compared with the drive’s 98 A output-current rating, while the application’s starting torque, overload requirement, acceleration time, braking requirements, and operating duty should also be considered.

For applications around the 75 kW level, the 20G1ANF082JA0NNNNN is a closely related lower-capacity option. For larger motor systems, the 20G1ANF119JA0NNNNN and 20G1ANF142JA0NNNNN provide higher current and power capacity.

In practical terms, the 20G1ANF098JA0NNNNN occupies an important position in the 690 V PowerFlex 755 range: it provides a substantial increase over the 82 A / 75 kW class while remaining within the same general Frame 6 high-power drive platform.
