Allen-Bradley 20F1ANF015JA0NNNNN — Detailed Product Overview, Technical Parameters, Applications, Advantages and Related Models

1. Product Introduction

The 20F1ANF015JA0NNNNN is an Allen-Bradley PowerFlex 753 AC Drive designed for industrial motor-speed control and variable-frequency motor applications.

This model is a 690 VAC, three-phase, 15 A air-cooled AC drive with a Normal Duty rating of 11 kW and a Heavy Duty rating of 7.5 kW.

It uses a Frame 6, open-type construction and is intended to be installed inside a suitable industrial electrical enclosure.

The drive includes embedded I/O, AC input with precharge, no DC terminals, a filtered configuration, an installed common-mode jumper, and a dynamic braking transistor.

The inclusion of the dynamic braking transistor is one of the useful characteristics of this particular JA0 configuration. It makes the drive more suitable for applications where controlled deceleration and braking performance are important.

The standard configuration is supplied without a Human Interface Module, so the drive is identified as Blank / No HIM.

The electrical rating that stands out most clearly is the 15 A, 690 VAC configuration.

For Normal Duty applications, the drive is rated at approximately 11 kW, while the Heavy Duty rating is 7.5 kW.

This distinction is important because the same physical drive can be used for different application classes depending on the required load and overload characteristics.

---

4. Product Model Identification

The complete catalog number is:

20F1ANF015JA0NNNNN

The model belongs to the PowerFlex 753 family.

The 015 section identifies the 15 A size.

The J configuration corresponds to the version with the common-mode jumper installed.

The A configuration in the option structure identifies the version incorporating a dynamic braking transistor.

The remaining catalog-number characters identify the detailed construction and option configuration.

For purchasing, maintenance and replacement purposes, it is best to use the complete catalog number rather than referring to the drive only as a “15 A PowerFlex 753”.

Different catalog numbers can have similar voltage, current and power ratings while having different braking, filtering, common-mode or other configuration characteristics.

---

5. What Is the PowerFlex 753?

The PowerFlex 753 is an industrial AC drive platform intended for applications where the speed and operating behavior of an AC motor need to be controlled electronically.

A conventional motor starter generally provides basic start and stop functionality.

A variable-frequency drive goes much further.

It can control motor speed, acceleration and deceleration while also providing various motor-control and protection functions.

This makes the PowerFlex 753 suitable for industrial machines where the motor is an active part of the production process.

For example, a conveyor may need to run at different speeds depending on the production stage.

A pump may need to increase or reduce speed according to process demand.

A mixer may require several operating speeds.

A high-inertia machine may need controlled deceleration.

These are situations where a variable-frequency drive becomes considerably more useful than a basic motor starter.

---

6. 690 VAC Three-Phase Design

The 690 VAC three-phase rating is one of the defining features of this model.

It is intended for industrial electrical systems using higher-voltage three-phase motor supplies.

The 690 VAC class is commonly associated with industrial machinery and larger electrical systems.

The drive should be matched to the actual motor nameplate rather than selected solely according to the apparent motor kW rating.

Important motor information includes:

• Rated voltage
• Rated current
• Rated power
• Rated frequency
• Rated speed
• Motor type
• Power factor
• Efficiency
• Starting torque
• Load characteristics

The motor’s rated current is particularly important when selecting the drive.

---

7. 15 A Output Rating

The drive has a 15 A output-current rating.

This places it above the 12 A version in the same 690 VAC PowerFlex 753 family.

The additional current capacity makes the model suitable for a larger motor or a machine requiring more available output current.

The 15 A rating should not be interpreted as meaning that every 11 kW motor is automatically suitable.

The final selection must consider both motor current and application duty.

For a normal-load centrifugal application, the 11 kW Normal Duty rating may be appropriate.

For a demanding constant-torque application, the 7.5 kW Heavy Duty rating becomes the more relevant figure.

---

8. Normal Duty Rating — 11 kW

The Normal Duty rating is:

11 kW

This makes the model suitable for many medium-power industrial applications.

Normal Duty applications generally have a load profile where the motor does not continuously demand heavy overload torque.

Typical examples include:

• Centrifugal pumps
• Fans
• Blowers
• Ventilation systems
• Light-to-medium conveyors
• Process machinery
• General industrial motor applications

---

9. Heavy Duty Rating — 7.5 kW

The Heavy Duty rating is:

7.5 kW

Heavy Duty operation should be considered when the machine requires greater torque or more demanding acceleration and overload performance.

Typical examples include:

• Heavy conveyors
• Mixers
• Material-handling machinery
• Constant-torque equipment
• Machines with frequent acceleration
• Machines with frequent deceleration
• Machines with high starting torque

This means that a 7.5 kW motor can be a very natural application for this drive when the machine has a demanding load profile.

---

10. Normal Duty and Heavy Duty Comparison

Parameter	Normal Duty	Heavy Duty
Rated Current Class	15 A	15 A drive class
Power Rating	11 kW	7.5 kW
Typical Load	Variable / centrifugal	Constant torque
Typical Equipment	Fans, pumps, blowers	Conveyors, mixers
Overload Requirement	Moderate	Higher
Starting Demand	Moderate	More demanding
Recommended Selection Basis	Motor current + ND load	Motor current + HD load

The difference between Normal Duty and Heavy Duty is not simply a marketing classification.

It reflects the type of thermal and overload demand expected from the drive.

For this reason, an engineer should first determine the actual load profile before selecting the motor-drive combination.

---

11. Dynamic Braking Transistor

One of the notable features of 20F1ANF015JA0NNNNN is its:

DB Transistor

A dynamic braking transistor allows the drive to work with an appropriate external braking resistor arrangement when the application needs controlled dissipation of regenerative energy.

This can be valuable when a motor must decelerate quickly.

During deceleration, a motor can temporarily return energy toward the drive’s DC bus.

If that energy is not managed appropriately, the DC-bus voltage can rise.

A braking system provides a method of managing this energy.

Typical applications where braking can be important include:

• Conveyors
• Centrifuges
• High-inertia machinery
• Hoisting-related equipment
• Material-handling systems
• Rapid stopping applications
• Machines with frequent speed changes

The presence of a braking transistor does not by itself mean that every application automatically has a complete braking system.

The braking resistor, wiring, thermal requirements and application duty must be selected separately according to the actual machine requirements.

---

12. Air-Cooled Construction

The drive uses a forced-air cooling arrangement.

The power electronics generate heat during operation.

The cooling system moves air through the appropriate heat-dissipation areas to control operating temperature.

This makes cabinet ventilation an important part of the installation.

The cabinet should provide sufficient space for:

• Air circulation
• Heat removal
• Cable routing
• Maintenance
• Electrical clearance
• Service access

When several drives are installed in one cabinet, their combined heat generation must be considered.

---

13. Frame 6 Construction

The 20F1ANF015JA0NNNNN uses a Frame 6 enclosure size.

The approximate overall dimensions for this Frame 6 open-type arrangement are:

665.5 × 308 × 346.4 mm

The approximate weight is:

38.6 kg

This is a substantial industrial drive.

It should therefore be treated as a cabinet-mounted industrial component rather than a small machine-mounted inverter.

The physical dimensions are particularly important when replacing an older drive because electrical compatibility does not automatically guarantee mechanical compatibility.

---

14. Mechanical Parameters

Mechanical Parameter	Specification
Frame	Frame 6
Enclosure	Open Type
Cooling	Forced Air
Height	Approx. 665.5 mm
Width	Approx. 308 mm
Depth	Approx. 346.4 mm
Overall Dimensions	Approx. 665.5 × 308 × 346.4 mm
Weight	Approx. 38.6 kg
Mounting	Cabinet / Panel
Installation	Industrial Electrical Enclosure
Ventilation	Required
Maintenance Clearance	Required
Heat Dissipation	Required

The dimensions and weight are useful for preliminary cabinet planning.

For final engineering work, the actual mechanical drawing for the specific installation should always be checked, especially when accessories, wiring arrangements or additional options are installed.

---

15. Open-Type Enclosure

The drive is an Open Type product.

This means the drive itself is intended to be installed within a suitable enclosure or electrical cabinet that provides the required environmental protection.

The cabinet should be designed to protect the drive from:

• Dust
• Moisture
• Direct contamination
• Excessive heat
• Mechanical damage
• Uncontrolled access

The cabinet must also allow adequate cooling.

A sealed cabinet without suitable thermal management can create excessive internal temperature.

---

16. AC Input with Precharge

The input configuration is:

AC Input with Precharge

The model does not have external DC terminals in this configuration.

The precharge system forms part of the drive’s incoming power architecture.

This is important when designing or modifying the electrical system.

It also matters when comparing this model with another PowerFlex configuration because two visually similar drives can have different input arrangements.

---

17. Filtering and Common-Mode Configuration

The model is specified as:

Filtered, CM Jumper Installed

This configuration is relevant to the electrical characteristics of the installation.

Industrial drives use high-frequency switching devices.

As a result, proper grounding, motor-cable routing, shielding and cabinet design can have a major influence on electromagnetic behavior.

The drive’s filtering configuration should therefore be considered together with the rest of the installation.

---

18. Embedded I/O

The PowerFlex 753 platform provides embedded I/O for integration into industrial control systems.

This can allow the drive to receive and provide signals associated with:

• Start commands
• Stop commands
• Speed references
• Status
• Fault conditions
• Interlocks
• Process signals

The actual I/O architecture should be selected according to the machine’s control requirements.

Additional I/O or communication options can also be used when the standard configuration does not provide everything required by the machine.

---

19. Blank / No HIM Configuration

The model is specified as:

Blank (No HIM)

HIM refers to the Human Interface Module.

A blank configuration does not mean that the drive lacks control capability.

It simply means that a standard mounted HIM is not included as part of this particular catalog configuration.

For applications requiring local operator interaction, a compatible interface can be added as appropriate.

In a PLC-controlled machine, local drive-panel operation may not be necessary because commands and monitoring can be handled by the machine-control system.

---

20. Main Product Applications

20.1 Conveyor Systems

Conveyor systems are an excellent application for this type of drive.

A conveyor may need to start smoothly, operate at different speeds and stop under controlled conditions.

The drive can provide adjustable acceleration and deceleration.

The dynamic braking transistor is also potentially useful where the conveyor has significant inertia and requires controlled stopping.

Applications include:

• Production conveyors
• Packaging conveyors
• Material-transfer systems
• Warehouse equipment
• Processing lines
• Heavy-duty conveyor systems

---

21. Pump Applications

The drive can be used for industrial pump systems where variable flow or pressure is required.

Typical applications include:

• Water circulation
• Process pumps
• Cooling systems
• Industrial fluid transfer
• Pressure-control systems
• Process-water systems

For centrifugal pump applications, Normal Duty operation can often be more relevant than Heavy Duty operation.

The actual pump motor current should still be checked carefully.

---

22. Fan and Blower Applications

Fans and blowers are another common application.

The required airflow may change during the operating cycle.

Instead of running the motor continuously at full speed, the drive can adjust the motor speed according to demand.

This provides better process control and may also reduce unnecessary energy consumption.

Typical applications include:

• Industrial ventilation
• Exhaust systems
• Cooling equipment
• Air handling
• Process ventilation
• Dust collection
• Industrial blowers

---

23. Mixer Applications

Mixers can have very different torque requirements depending on the material being processed.

A mixer may start at low speed, increase speed during the main process and then slow down before discharge.

The drive allows the operating speed to be adjusted to suit the process.

For applications with high starting torque, the Heavy Duty rating should be considered carefully.

24. Material-Handling Applications

Material-handling systems frequently require controlled acceleration and stopping.

Sudden starting can place high stress on:

• Gearboxes
• Couplings
• Shafts
• Chains
• Belts
• Bearings

A variable-frequency drive can provide a more controlled operating profile.

When rapid stopping is required, the dynamic braking capability of the JA0 configuration becomes particularly useful.

25. High-Inertia Applications

High-inertia machinery can continue rotating for a considerable amount of time after the drive reduces output frequency.

If the machine needs to stop quickly, regenerative energy can become significant.

Examples include:

• Large fans
• Centrifugal equipment
• Rollers
• Large rotating assemblies
• Certain processing machines

In such applications, the braking arrangement should be designed carefully.

The braking transistor is an important advantage, but the complete braking system still needs to be engineered around the actual machine inertia and stopping frequency.

26. Manufacturing Machinery

The drive can be used in many general industrial machines.

Examples include:

• Processing machinery
• Packaging systems
• Production lines
• Material transport
• Industrial automation equipment
• Machine systems
• General-purpose motor-driven equipment

The main advantage is that motor speed can become part of the overall production-control strategy.

---

27. Main Product Advantages

27.1 690 VAC Industrial Operation

The 690 VAC rating makes this model appropriate for industrial high-voltage motor systems.

This is one of the main reasons to choose this product over smaller low-voltage drive families.

27.2 15 A Capacity

The 15 A current class provides more capacity than the 12 A version in the same family.

This makes it suitable for applications requiring a larger motor or higher operating current.

27.3 11 kW Normal Duty Rating

The 11 kW Normal Duty rating provides useful capacity for medium-power industrial machinery.

It is especially attractive for fans, pumps, blowers and other variable-load equipment.

27.4 7.5 kW Heavy Duty Rating

The 7.5 kW Heavy Duty rating makes the drive suitable for more demanding constant-torque applications within its rated limits.

27.5 Built-In Dynamic Braking Transistor

The DB transistor is a significant advantage for applications where braking energy needs to be managed.

It can simplify the drive selection when an external braking resistor is required.

27.6 Variable-Speed Operation

The drive allows the motor to operate at different speeds.

This provides greater flexibility than fixed-speed motor operation.

27.7 Controlled Acceleration

The acceleration profile can be adjusted to suit the mechanical system.

This can reduce sudden mechanical stress during starting.

27.8 Controlled Deceleration

Controlled deceleration is useful for conveyors, rotating machinery and process equipment.

When combined with an appropriately engineered braking system, stopping performance can be improved significantly.

27.9 Embedded I/O

Embedded I/O simplifies integration into industrial control systems.

The drive can form part of a larger automation architecture without requiring every basic control signal to be handled through additional equipment.

27.10 Industrial Frame 6 Design

The Frame 6 construction is appropriate for larger industrial applications where a compact drive would not provide sufficient power or functionality.

28. Five Recommended Models from the Same Series

The following models are useful related choices within the PowerFlex 753 690 VAC family.

Model	Voltage	Current	Normal Duty	Heavy Duty	Frame	Dimensions	Weight
20F1ANF012JA0NNNNN	690 VAC	12 A	7.5 kW	5.5 kW	6	Approx. 665.5 × 308 × 346.4 mm	Approx. 38.6 kg
20F1ANF015JN0NNNNN	690 VAC	15 A	11 kW	7.5 kW	6	Frame 6 configuration	Approx. 38.6 kg class
20F1ANF020JA0NNNNN	690 VAC	20 A	15 kW	11 kW	6	Frame 6 configuration	Approx. 38.6 kg class
20F1ANF023JA0NNNNN	690 VAC	23 A	18.5 kW	15 kW	6	Frame 6 configuration	Approx. 38.6 kg class
20F1ANF030JA0NNNNN	690 VAC	30 A	22 kW	18.5 kW	6	Frame 6 configuration	Approx. 38.6 kg class

The 20F1ANF012JA0NNNNN is the closest lower-capacity related model.

The 20F1ANF015JN0NNNNN is particularly interesting because it has the same 15 A and power ratings but uses a different option configuration.

The 20 A, 23 A and 30 A models are appropriate when higher motor capacity is required.

When replacing a drive, however, the option suffix should be compared carefully rather than assuming that two models with the same electrical rating are interchangeable.

29. Additional Related Models

Model	Voltage	Current	Normal Duty	Heavy Duty	Typical Application	Dimensions	Weight
20F1ANF034JA0NNNNN	690 VAC	34 A	30 kW	22 kW	Large industrial machinery	Configuration-dependent	Configuration-dependent
20F1ANF046JA0NNNNN	690 VAC	46 A	37 kW	30 kW	Large process equipment	Configuration-dependent	Configuration-dependent
20F1ANF050JA0NNNNN	690 VAC	50 A	45 kW class	37 kW class	High-power motor systems	Configuration-dependent	Configuration-dependent
20F1ANF061JA0NNNNN	690 VAC	61 A	55 kW	45 kW	High-capacity industrial systems	Configuration-dependent	Configuration-dependent
20F1ANF082JA0NNNNN	690 VAC	82 A	75 kW	55 kW	Large motor applications	Configuration-dependent	Configuration-dependent

These are capacity-expansion options rather than direct replacements.

As the current rating increases, the motor power capability also increases, but cabinet design, thermal management, cable sizing, protection and installation requirements must be reconsidered.

30. Five Representative Same-Brand Models

The following models provide a broader comparison across the same brand’s drive portfolio.

Model	Series	Voltage Class	Current / Power Class	Typical Application	Approx. Dimensions	Approx. Weight
20F1ANF015JA0NNNNN	PowerFlex 753	690 VAC	15 A / 11 kW ND	Medium industrial machinery	665.5 × 308 × 346.4 mm class	38.6 kg class
20F1ANF020JA0NNNNN	PowerFlex 753	690 VAC	20 A / 15 kW ND	Industrial process equipment	Frame-dependent	Frame-dependent
20F1ANF030JA0NNNNN	PowerFlex 753	690 VAC	30 A / 22 kW ND	Larger industrial machinery	Frame-dependent	Frame-dependent
25B-D017N114	PowerFlex 525	480 VAC class	17 A class	Compact industrial machinery	Compact frame	Approx. 4–6 kg class
25B-D024N114	PowerFlex 525	480 VAC class	24 A class	Larger compact machinery	Compact frame	Approx. 5–7 kg class

The PowerFlex 525 examples are significantly more compact than the Frame 6 PowerFlex 753.

They are therefore better considered when the application does not require the 690 VAC electrical class or the larger PowerFlex 753 platform.

31. Model Comparison

Model	Series	Voltage	Current	ND Power	HD Power	Frame	Main Application
20F1ANF012JA0NNNNN	PowerFlex 753	690 VAC	12 A	7.5 kW	5.5 kW	6	Medium motor

Production Equipment	Very Good	Depends on Load
Rapid-Stop Machinery	Excellent	Evaluate DB System

---

33. Conveyor Application Advantages

For conveyor applications, the drive can control the entire starting and stopping process.

Instead of applying full motor torque immediately, the motor can be accelerated progressively.

This can reduce mechanical shock and make the machine easier to operate.

The dynamic braking transistor can also be useful where the conveyor needs to stop quickly or where the load has substantial rotational or moving inertia.

This makes the 20F1ANF015JA0NNNNN a particularly interesting option for industrial material-handling equipment.

34. Pump Application Advantages

For pump applications, the main benefit is speed control.

A pump does not always need to run at full speed.

The drive can adjust motor speed according to the required operating point.

For a properly engineered system, this can provide:

• Better process control
• Adjustable flow
• Adjustable pressure
• Smoother starting
• Reduced mechanical stress
• Potential energy savings

The actual energy performance depends on the pump system and operating profile.

35. Fan Application Advantages

Fan systems frequently operate under changing demand.

If the required airflow changes, the motor speed can be adjusted instead of keeping the fan at maximum speed.

This provides a more flexible operating system.

For large industrial ventilation systems, this can be particularly useful because the fan can follow the actual process demand.

36. High-Inertia Machine Advantages

High-inertia machinery can present a special challenge during deceleration.

The machine may continue rotating even after the drive reduces motor output.

The regenerated energy can raise the DC-bus voltage.

The dynamic braking transistor in this model provides a useful method of managing regenerative energy through a properly selected braking resistor.

This is one of the key advantages of the JA0 configuration compared with a configuration without a braking transistor.

37. Electrical Installation Considerations

The installation should consider:

• Incoming 690 VAC power
• Three-phase supply
• Motor cable sizing
• Motor grounding
• Drive grounding
• Cabinet temperature
• Airflow
• Short-circuit protection
• Motor protection
• Electromagnetic compatibility
• Control wiring
• Braking resistor requirements
• Maintenance access

The drive should be installed according to the requirements of the actual electrical system and the motor manufacturer’s specifications.

38. Cabinet Design Considerations

The approximate dimensions are:

665.5 mm high

308 mm wide

346.4 mm deep

The approximate weight is:

38.6 kg

This means that cabinet space should be planned carefully.

The cabinet should also provide sufficient room around the drive for cooling and maintenance.

The drive should not be installed immediately next to heat-producing equipment without considering the resulting temperature rise.

39. Heat Management

Because the drive is air cooled, heat management is important.

The cabinet designer should consider the total heat generated by:

• The drive
• Other drives
• Power supplies
• Transformers
• Contactors
• PLC equipment
• Control components

If the cabinet becomes too hot, the drive’s operating conditions can deteriorate.

Proper ventilation and thermal design are therefore important parts of a reliable installation.

40. Maintenance Recommendations

Routine maintenance should focus on the following areas:

Maintenance Area	Recommended Attention
Cooling Fans	Check operation and airflow
Air Passages	Keep clean
Cabinet	Check dust and contamination
Power Connections	Check for loose connections
Grounding	Inspect regularly
Motor Cable	Check insulation and connections
Control Wiring	Check terminals
Braking System	Inspect resistor and wiring
Drive Parameters	Maintain backup
Fault History	Review abnormal events
Cabinet Temperature	Monitor operating conditions

Industrial drives generally perform best when heat, dust and electrical connection problems are controlled before they become serious faults.

41. Replacement Considerations

If an existing 20F1ANF015JA0NNNNN is being replaced, the replacement should not be selected only by comparing the kW rating.

The following should be checked:

Selection Item	Requirement
Voltage	690 VAC
Phase	Three Phase
Current	15 A class
Normal Duty	11 kW
Heavy Duty	7.5 kW
Frame	Frame 6
Cooling	Air Cooled
Enclosure	Open Type
Input	AC with Precharge
DC Terminals	None
Filtering	Filtered
CM Jumper	Installed
Dynamic Braking	DB Transistor
Embedded I/O	Required
HIM	Blank / No HIM
Dimensions	Approx. 665.5 × 308 × 346.4 mm
Weight	Approx. 38.6 kg
Motor Voltage	Must match
Motor Current	Must match
Load Type	Must be evaluated
Braking Requirement	Must be evaluated
Cabinet Space	Must be adequate

---

42. Why the Dynamic Braking Option Matters

The presence of the dynamic braking transistor gives this model an advantage in applications where rapid stopping is required.

Consider a conveyor carrying a heavy load.

When the conveyor is running, the motor and mechanical system contain kinetic energy.

When the drive commands the machine to stop, that energy has to go somewhere.

If the machine decelerates slowly, the energy can be managed over a longer period.

If the machine must stop quickly, regenerative energy can become much greater.

A braking system can help manage that energy.

Therefore, this model is especially attractive when braking is an important part of the machine design.

43. Important Limitation

Although the model has a dynamic braking transistor, this does not mean that the drive automatically contains every component required for a complete dynamic braking installation.

The appropriate braking resistor and associated installation must be selected according to:

• Motor power
• Motor inertia
• Load inertia
• Deceleration time
• Number of braking cycles
• Duty cycle
• Ambient temperature

This is particularly important for machines that stop frequently.

46. Final Evaluation

The 20F1ANF015JA0NNNNN is a robust industrial AC drive designed around the PowerFlex 753 platform.

Its main electrical characteristics are 690 VAC, three-phase input, 15 A output, 11 kW Normal Duty and 7.5 kW Heavy Duty.

The model uses a Frame 6 open-type air-cooled construction, with approximate dimensions of 665.5 × 308 × 346.4 mm and an approximate weight of 38.6 kg.

One of the most useful characteristics of this particular configuration is the dynamic braking transistor.

That feature makes the model especially attractive for machinery where the motor needs to decelerate quickly or where regenerative energy needs to be managed through an appropriately designed braking system.

The drive is also equipped with embedded I/O, making it suitable for integration into industrial control systems.

Its 690 VAC rating makes it appropriate for industrial higher-voltage motor systems, while the 11 kW Normal Duty rating provides a useful capacity for pumps, fans, blowers and other variable-load equipment.

For more demanding constant-torque applications, the 7.5 kW Heavy Duty rating should be used as the selection reference.

The most closely related models include 20F1ANF012JA0NNNNN, 20F1ANF015JN0NNNNN, 20F1ANF020JA0NNNNN, 20F1ANF023JA0NNNNN and 20F1ANF030JA0NNNNN.

These models provide a convenient progression when comparing different current and power requirements within the same PowerFlex 753 family.

Overall, 20F1ANF015JA0NNNNN is best suited to industrial applications that require 690 VAC three-phase motor control, approximately 15 A output capacity, 11 kW Normal Duty operation, 7.5 kW Heavy Duty capability, variable-speed control and dynamic braking capability.

It is a particularly practical choice for conveyors, pumps, fans, blowers, mixers, material-handling systems, high-inertia equipment and general industrial machinery where controlled motor operation is more important than simple start/stop control.
