6. Output Current

The most important electrical rating for motor selection is the 17 A normal-duty continuous output current.

The drive is designed for motors whose operating current falls within the applicable drive rating.

The horsepower value is useful as a general selection guide, but motor current should normally be checked against the actual motor nameplate.

Motor current can be affected by:

• Motor voltage
• Motor efficiency
• Motor power factor
• Motor speed
• Motor construction
• Motor loading
• Service factor
• Ambient temperature
• Application duty

For this reason, a 15 HP motor should not automatically be connected simply because the drive has a 15 HP normal-duty label. The motor’s actual rated current and the required overload profile should also be checked.

---

7. Normal-Duty Rating

The normal-duty rating is approximately 15 HP.

This makes the drive suitable for many general-purpose industrial applications where the motor operates under moderate loading conditions.

Typical examples include:

• Pumps
• Fans
• Blowers
• Conveyors
• Feeders
• General material handling
• Production machinery
• Packaging equipment
• Process equipment

Normal-duty selection should be based on the actual motor current and application conditions.

---

8. Heavy-Duty Rating

The heavy-duty rating is approximately 10 HP.

Heavy-duty selection is more important when the machine requires:

• Higher starting torque
• Frequent acceleration
• Frequent deceleration
• Greater overload capability
• High mechanical loading
• Repeated load changes

Applications such as heavily loaded conveyors, mixers, material-handling machinery, and high-inertia equipment may require a heavy-duty selection approach.

The heavy-duty rating should always be checked against the actual motor current and overload requirement.

---

9. 600 VAC Three-Phase Design

The drive is intended for a 600 VAC three-phase industrial power system.

This is an important distinction when comparing it with other models.

A drive with the same current rating but a different voltage class cannot automatically be used as a replacement.

Before selecting a replacement or alternative, verify:

Selection Item	Required Check
Supply Voltage	600 VAC class
Number of Phases	3 Phase
Motor Voltage	Compatible with drive output
Motor Current	Within drive rating
Motor Horsepower	Within applicable duty rating
Duty	Normal / Heavy
Braking	Required or not required
Communication	Required network type
Enclosure	Suitable cabinet installation
Frame	Mechanical compatibility

---

10. Variable Frequency Motor Control

The primary function of the drive is to convert fixed-frequency electrical power into a controlled variable-frequency output for the motor.

This allows the motor to operate at different speeds.

A traditional motor starter mainly provides:

Start → Run → Stop

A variable frequency drive provides much greater control:

Start → Accelerate → Run at selected speed → Change speed → Decelerate → Stop

This is particularly useful in automated machinery.

---

11. Controlled Acceleration

The drive can control how quickly the motor accelerates.

Instead of applying full operating speed immediately, the drive can increase motor frequency gradually.

Controlled acceleration can reduce mechanical stress on:

• Motor shafts
• Gearboxes
• Couplings
• Bearings
• Belts
• Chains
• Rollers
• Conveyor structures
• Machine frames

This can improve machine operating smoothness and reduce sudden mechanical loading.

---

12. Controlled Deceleration

The drive can also provide controlled deceleration.

This is useful when a machine must stop smoothly or when the process requires a defined stopping profile.

Typical applications include:

• Conveyor stopping
• Packaging machinery
• Feeders
• Roll handling
• Material handling
• Process machinery
• High-inertia loads

The required deceleration time depends on the mechanical load, motor characteristics, programmed drive parameters, DC-bus behavior, and braking system.

---

13. Dynamic Braking

The 20G11NE017JA0NNNNN includes an internal dynamic-braking transistor.

This is an important feature for applications where the motor must decelerate relatively quickly.

When a motor decelerates, mechanical energy can be returned to the drive’s DC bus.

A braking resistor can be used to dissipate this energy.

The internal braking transistor provides the switching function required for such a braking arrangement.

Potential applications include:

• High-inertia conveyors
• Rapid-cycle machinery
• Feed systems
• Material-handling systems
• Production machines
• Machines requiring controlled stopping

The braking resistor itself must be appropriately selected for the actual braking energy and duty cycle.

---

14. Embedded EtherNet/IP

The drive includes embedded EtherNet/IP communication.

This makes it suitable for integration into a networked automation architecture.

A typical arrangement can be represented as:

Controller

↓

Industrial Ethernet Network

↓

20G11NE017JA0NNNNN

↓

AC Motor

The network can be used to exchange operating commands and drive information.

Typical Information	Function
Start Command	Starts motor operation
Stop Command	Stops motor operation
Speed Reference	Defines desired speed
Direction Command	Controls direction
Enable	Allows drive operation
Reset	Resets suitable faults
Drive Status	Reports operating condition
Output Frequency	Provides operating-speed information
Output Current	Provides loading information
Fault Status	Identifies drive faults
Alarm Status	Identifies warnings
Operating State	Reports drive condition

This is useful for centralized machine automation.

---

15. Blank / No HIM Configuration

The model uses a blank / no HIM configuration.

HIM means Human Interface Module.

A local operator display is therefore not included as part of this particular configuration.

This configuration can be useful when the machine already has a centralized operator interface.

For example, an industrial system may use:

• PLC control
• Central HMI
• Supervisory control
• Industrial Ethernet
• Remote maintenance interface

In such a system, a separate local display on every drive may not be necessary.

---

16. CM Jumper Installed

The J configuration in the catalog number corresponds to the common-mode jumper being installed.

This is an important distinction from similarly numbered configurations using a different filtering/jumper arrangement.

The CM jumper configuration can affect the electrical relationship between the drive’s common-mode components and ground.

The actual grounding and EMC installation should follow the electrical design requirements for the application.

---

17. Filtered EMC Configuration

The drive uses a filtered configuration.

EMC performance is influenced by the complete installation, not simply the drive itself.

Important installation factors include:

• Motor cable construction
• Cable length
• Cable shielding
• Grounding
• Cabinet bonding
• Cable routing
• Separation between power and control cables
• Communication cable routing
• Motor frame grounding
• Proper termination

The drive’s filter arrangement should therefore be considered together with the complete machine electrical design.

---

18. Forced-Air Cooling

The drive is air cooled.

The power electronics generate heat during normal operation.

Forced-air cooling moves air through the drive to remove heat.

Cabinet designers should account for:

• Ambient temperature
• Drive heat loss
• Air circulation
• Fan operation
• Cabinet ventilation
• Filter condition
• Other heat-generating devices
• Required clearances

If several drives are installed in the same cabinet, their combined heat generation must be considered.

---

19. Open-Type Construction

The drive uses an open-type construction.

It should therefore be installed in an appropriate electrical enclosure.

The cabinet should protect the drive from unsuitable environmental conditions such as:

• Water
• Oil
• Excessive dust
• Metal particles
• Conductive contamination
• Chemical contamination
• Condensation

The enclosure must also provide sufficient ventilation and thermal management.

---

20. IP20/IP00 Class

The drive is an open-type industrial drive and is intended to be protected by the surrounding cabinet or installation.

This means the drive should not be treated as a standalone outdoor device.

The final enclosure should be selected according to the environment.

For example:

Environment	Consideration
Clean electrical room	Standard cabinet may be adequate
Factory floor	Cabinet protection required
Dusty area	Additional enclosure protection may be required
Wet area	Higher enclosure protection required
Washdown area	Special enclosure design required
Corrosive environment	Material and filtration considerations required

---

21. Product Applications

The 20G11NE017JA0NNNNN is suitable for many industrial motor-control applications.

Application	Suitability	Main Benefit
Conveyors	Excellent	Adjustable speed and smooth acceleration

Production Machinery	Excellent	Networked motor control
Process Machinery	Very Good	Variable-speed operation
Mixers	Good	Adjustable motor speed
Machine Auxiliaries	Excellent	Centralized automation
High-Inertia Machinery	Good	Dynamic-braking capability

---

22. Conveyor Applications

Conveyors are a particularly suitable application.

A conveyor motor may need to operate at different speeds depending on production requirements.

The drive can provide:

• Smooth starting
• Adjustable speed
• Controlled stopping
• Speed changes
• Network-based commands
• Drive status feedback
• Fault information

Dynamic braking can also be valuable when a conveyor has significant rotating or moving mass.

---

23. Pump Applications

The drive can regulate the motor speed of a pump.

This can be useful for:

• Water circulation
• Cooling systems
• Industrial fluid transfer
• Process circulation
• Utility systems
• General fluid handling

The motor does not necessarily need to operate continuously at maximum speed.

The speed can be adjusted according to process requirements.

Actual energy savings depend on the pump type, system curve, operating point, motor efficiency, and process profile.

---

24. Fan Applications

Fans and blowers often have changing airflow requirements.

A variable-speed drive can adjust the motor speed to match the required airflow.

Typical applications include:

• Factory ventilation
• Exhaust systems
• Cooling systems
• Industrial air handling
• Process ventilation
• Machine cooling

This allows the drive to become part of the overall process-control strategy.

---

25. Feeder Applications

Industrial feeders frequently require controlled material movement.

The drive can adjust motor speed to influence:

• Feed rate
• Production rate
• Material quantity
• Machine synchronization
• Product throughput

This can be useful in:

• Production lines
• Packaging systems
• Material-processing equipment
• Conveyor feeders
• Automated handling systems

---

26. Packaging Machinery

Packaging machinery often uses several motors that must operate at coordinated speeds.

The drive can be used for:

• Feed mechanisms
• Conveyor sections
• Rollers
• Material transport
• Auxiliary machines
• Adjustable-speed mechanisms

EtherNet/IP communication can make the drive easier to integrate with the machine’s overall control system.

---

27. Material Handling

Material-handling machinery can benefit from controlled motor operation.

Potential applications include:

• Transfer conveyors
• Sorting machinery
• Automated transport
• Production conveyors
• Feed systems
• Material positioning

Controlled acceleration and deceleration can reduce mechanical shock and improve overall machine behavior.

---

34. Same-Series Model Selection

20G11NE011JA0NNNNN

This model is suitable when the motor requires less current than the 17 A version.

It can be considered for smaller 600 VAC motors and applications where the 10 HP normal-duty capacity is sufficient.

---

20G11NE017JA0NNNNN

This is the direct model being described here.

It provides:

• 17 A output
• 15 HP normal duty
• 10 HP heavy duty
• Frame 3
• 600 VAC

It is a practical mid-range choice in the 600 VAC family.

---

20G11NE022JA0NNNNN

---

37. Why Select the 17 A Model?

The 20G11NE017JA0NNNNN occupies a useful position between the smaller and larger drives in the 600 VAC family.

It is suitable when:

• The motor current is above the smaller 11 A class
• A 15 HP normal-duty rating is required
• The system uses 600 VAC
• EtherNet/IP communication is needed
• Dynamic braking is useful
• A Frame 3 mechanical format is acceptable
• A local HIM is not required

It provides a good balance between motor capacity and cabinet space.

---

38. Advantages for Machine Builders

For machine builders, the main advantages are:

1. Adjustable motor speed
2. Controlled acceleration
3. Controlled deceleration
4. Network communication
5. Industrial diagnostics
6. Dynamic braking capability
7. Medium motor capacity
8. Compact Frame 3 design
9. Centralized control capability
10. Flexible application possibilities

The drive can therefore be used as an integrated component of a complete machine rather than simply as an independent motor starter.

---

39. Advantages for Automation Engineers

The embedded communication capability makes the drive useful for automation engineers.

A machine controller can coordinate:

• Motor start
• Motor stop
• Speed command
• Direction
• Acceleration
• Deceleration
• Status
• Fault information
• Operating feedback

This allows the motor to become part of the machine’s control sequence.

For example:

Sensor → Controller → Drive → Motor → Mechanical Process

The drive can therefore form an important link between the electrical system and the mechanical process.

---

40. Advantages for Maintenance Personnel

The drive can provide useful operating and fault information.

This can help maintenance personnel investigate issues involving:

• Excessive motor current
• Mechanical overload
• Acceleration problems
• Deceleration problems
• Communication problems
• Electrical faults
• Thermal conditions
• Incorrect configuration

Instead of treating the motor simply as an on/off device, maintenance personnel can use drive information to understand how the motor is behaving.

---

41. Energy Management

Variable-speed operation can be beneficial when a process does not require full motor speed all the time.

For example:

Process Condition	Possible Drive Operation
Maximum demand	High speed
Normal production	Medium speed
Reduced production	Lower speed
Setup	Low speed
Maintenance	Controlled low speed
Stop	Controlled deceleration

The actual energy benefit depends strongly on the application.

The greatest potential benefit is generally associated with processes where the required motor speed varies substantially during operation.

---

42. Cabinet Design Considerations

Because this is an open-type drive, the cabinet designer should consider the complete installation rather than only the drive dimensions.

Important considerations include:

• Cabinet height
• Cabinet width
• Cabinet depth
• Air circulation
• Heat dissipation
• Power cable routing
• Motor cable routing
• Communication cable routing
• Grounding
• Braking resistor placement
• Service access
• Clearance
• Ambient temperature

The approximate drive envelope is:

424 mm high × 170 mm wide × 212 mm deep

with an approximate weight of:

9.07 kg

---

43. Thermal Considerations

The drive generates heat during operation.

Heat generation increases with:

• Motor load
• Output current
• Switching activity
• Ambient temperature
• Application duty
• Cabinet temperature

The forced-air cooling system must remain unobstructed.

Air filters, if used in the cabinet, should be maintained because blocked airflow can increase internal temperature.

---

44. Motor Selection

The motor should be selected according to its actual nameplate data.

Important information includes:

Motor Parameter	Why It Matters
Rated Voltage	Must match drive output capability
Full-Load Current	Main drive sizing parameter
Horsepower	General capacity reference
Frequency	Determines base operating point
Speed	Required for application
Power Factor	Influences motor current
Efficiency	Influences power requirements
Duty	Determines overload requirements
Insulation	Important for inverter operation
Encoder	Required if feedback control is used

The drive’s 17 A rating should not be treated as permission to operate any 15 HP motor without checking its actual current.

---

45. Dynamic-Braking Application

The integrated dynamic-braking transistor is particularly useful when the application has significant stored mechanical energy.

Examples include:

• Large rotating assemblies
• High-speed conveyors
• Rapid stopping machinery
• Material-handling systems
• High-inertia rollers
• Production equipment

The braking resistor must be selected according to:

• Braking energy
• Braking frequency
• Deceleration time
• Load inertia
• Motor speed
• Duty cycle

Improper braking-resistor selection can result in overheating or drive faults.

---

46. Communication and Control

Embedded EtherNet/IP allows the drive to be incorporated into an industrial network.

A typical control sequence could be:

1. Controller sends enable command

↓

2. Drive becomes ready

↓

3. Controller sends speed reference

↓

4. Drive accelerates motor

↓

5. Drive reports operating status

↓

6. Controller changes speed as required

↓

7. Drive decelerates

↓

8. Drive reports stopped condition

This type of architecture is useful in automated production systems.

52. Conclusion

The 20G11NE017JA0NNNNN is a 600 VAC, three-phase PowerFlex 755 variable frequency drive intended for industrial motor-control applications.

Its 17 A output rating gives it an approximate 15 HP normal-duty capacity and approximately 10 HP heavy-duty capacity.

The Frame 3 mechanical format provides a practical solution for medium-size motor applications while keeping the drive within a relatively manageable cabinet footprint.

The drive’s embedded EtherNet/IP capability makes it suitable for automated machinery in which motor control, status monitoring, speed commands, and fault information need to be exchanged with a central controller.

The integrated dynamic-braking transistor is particularly useful for applications that require controlled deceleration or that contain significant mechanical inertia.

The blank/no-HIM configuration makes the drive suitable for systems where operation is managed through a PLC, HMI, industrial Ethernet network, or another centralized interface.

The drive is particularly well suited to:

• Conveyor systems
• Pumps
• Fans
• Blowers
• Feeders
• Packaging machinery
• Material-handling systems
• Production machinery
• Process equipment
• General industrial motor-control applications

For preliminary mechanical planning, the drive can be treated as approximately 424 mm high, 170 mm wide, and 212 mm deep, with an approximate product weight of 9.07 kg.

The five closest same-series comparison models are 20G11NE011JA0NNNNN, 20G11NE017JA0NNNNN, 20G11NE022JA0NNNNN, 20G11NE027JA0NNNNN, and 20G11NE032JA0NNNNN.

Among these, the 11 A model is appropriate for smaller motors, the 17 A model provides the middle 15 HP normal-duty capacity, the 22 A model provides additional current capacity, and the 27 A and 32 A models move into larger motor applications.

When choosing a replacement or alternative, the most important factors are not simply horsepower and physical size. The actual motor full-load current, supply voltage, duty cycle, overload requirement, braking requirement, communication architecture, cabinet conditions, ambient temperature, and mechanical installation requirements should all be checked before final selection.
