6. Electrical Characteristics

The 20G1AND361JN0NNNNN is intended for a 480 V-class three-phase industrial electrical system.

A 480 V-class drive is commonly used in larger industrial machinery and production equipment.

The drive receives three-phase AC input power and produces controlled three-phase output power for the motor.

The output frequency can be varied to regulate motor speed.

This makes it possible to match motor operation with the requirements of the mechanical process.

The exact continuous output-current capability associated with the 361 configuration should be confirmed against the actual product rating information before selecting the motor.

For engineering purposes, the motor’s full-load current should be treated as a primary sizing parameter.

Electrical Parameter	Engineering Consideration

---

8. Product Introduction

The 20G1AND361JN0NNNNN is designed for industrial motor applications where the machine requires controlled and adjustable motor operation.

A fixed-speed motor normally operates according to the electrical frequency supplied to it.

An adjustable-frequency drive introduces another level of control by changing the electrical output characteristics supplied to the motor.

This allows the motor to operate at different speeds.

The machine can therefore operate at different production rates without requiring constant mechanical speed changes.

The drive can also provide controlled acceleration and deceleration.

This is particularly useful for machinery with high inertia or equipment where sudden changes in speed could create mechanical stress.

---

9. Variable-Speed Operation

Variable-speed operation is one of the main functions of the product.

The motor speed can be adjusted according to a programmed speed reference.

The reference may come from local control, an external control signal or an automation system, depending on the configured application.

Variable-speed operation is particularly useful for:

• Conveyors.
• Pumps.
• Fans.
• Blowers.
• Rollers.
• Mixers.
• Feeders.
• Material-handling equipment.
• Processing machines.
• Production lines.

The ability to operate at different speeds can improve process flexibility.

---

10. Controlled Acceleration

Large industrial motors can create significant mechanical forces during startup.

A drive can gradually increase motor speed instead of applying a sudden full-speed command.

This controlled acceleration can reduce mechanical shock on:

• Gearboxes.
• Shafts.
• Couplings.
• Belts.
• Chains.
• Conveyor structures.
• Rollers.
• Mechanical transmission systems.

For machines with substantial rotating inertia, a properly configured acceleration profile can be particularly important.

---

11. Controlled Deceleration

The drive can also control the rate at which the motor slows down.

Controlled deceleration can help produce a smoother stopping process.

This is useful for:

• Conveyor systems.
• Material-handling equipment.
• Rollers.
• Process machinery.
• Large rotating equipment.
• Production machinery.

Where a machine must stop very quickly, the braking arrangement should be evaluated separately.

High-inertia loads can return energy to the drive during deceleration, so the complete braking design must match the application.

---

12. Torque Control

The PowerFlex 755 platform supports advanced motor-control functions suitable for applications where torque performance is important.

Torque control can be particularly useful when the mechanical load changes during operation.

Examples include:

• Conveyors.
• Mixers.
• Rollers.
• Material-handling systems.
• Processing equipment.
• Feed systems.
• Heavy rotating machinery.

The actual torque performance depends on the selected control mode, motor characteristics, application settings and commissioning parameters.

---

13. Motor Protection

The drive can monitor electrical and operating conditions and respond to abnormal conditions through programmed protective functions.

Potential protection functions include:

• Overcurrent protection.
• Overvoltage protection.
• Undervoltage protection.
• Motor overload protection.
• Thermal monitoring.
• Stall-related protection.
• Fault detection.

These functions can help protect the drive and connected motor.

Correct motor nameplate data and protection settings should be entered during commissioning.

---

14. Diagnostic Functions

Industrial machinery requires reliable troubleshooting information.

The drive can provide operating and diagnostic information that helps maintenance personnel investigate machine problems.

Typical information may include:

• Drive status.
• Motor current.
• Speed reference.
• Actual speed.
• Alarm condition.
• Fault condition.
• Operating parameters.
• Drive operating state.

This information can reduce troubleshooting time and help maintenance personnel determine whether a problem is associated with the electrical supply, motor, mechanical load, control command or drive.

---

15. Communication and Automation Integration

The drive can be incorporated into a larger automation architecture when the appropriate communication and control configuration is installed.

A typical system can be represented as:

Industrial Controller → Communication / Control Interface → AC Drive → Motor → Mechanical Load

The controller can provide speed and operating commands.

The drive then converts these commands into controlled motor operation.

The automation system can also receive operating information.

Data	Typical Purpose
Speed Reference	Sets desired operating speed
Actual Speed	Monitors motor operation
Motor Current	Indicates electrical loading
Drive Status	Indicates operating state
Alarm Status	Provides warning information
Fault Status	Identifies abnormal operation
Start/Stop Command	Controls motor operation

The cabinet should provide adequate airflow around the drive.

Air intake and exhaust paths should not be obstructed.

Dust accumulation should also be considered in environments with significant airborne particles.

If the drive is installed in a sealed enclosure, the cabinet may require a suitable heat-exchange or cooling arrangement.

The final cooling method should be selected according to:

• Drive losses.
• Ambient temperature.
• Cabinet dimensions.
• Installation altitude.
• Environmental conditions.
• Other equipment installed in the cabinet.

---

28. Energy Management

Variable-speed operation can provide energy-saving opportunities when the motor load changes with speed.

This is especially relevant to centrifugal pumps and fans.

When full output is not required, reducing motor speed can reduce the amount of power consumed by the motor system.

The actual energy result depends on:

• Motor characteristics.
• Load characteristics.
• Operating hours.
• Speed profile.
• Process requirements.
• Mechanical system design.

Therefore, the drive should be regarded as an important energy-management component rather than a guarantee of a fixed energy-saving percentage.

---

29. Maintenance Advantages

The drive can provide operating information that supports preventive maintenance and troubleshooting.

Useful information may include:

• Drive status.
• Motor current.
• Operating speed.
• Speed reference.

34. Practical Conveyor Application

A conveyor driven by a large AC motor can experience considerable mechanical stress if started at full speed immediately.

The drive allows the conveyor motor to accelerate gradually.

The conveyor can then operate at the required production speed.

If the production rate changes, the speed reference can be adjusted.

During stopping, controlled deceleration can reduce sudden mechanical forces.

This is especially valuable for long conveyors, heavy conveyors and systems transporting sensitive materials.

---

35. Practical Pump Application

A pump system may have different flow requirements during different production periods.

Running the motor continuously at full speed may not always be necessary.

With variable-speed control, the motor speed can be adjusted according to the required process flow.

This can improve process flexibility.

For suitable centrifugal pump systems, reduced-speed operation can also create opportunities for lower energy consumption.

---

36. Practical Fan and Blower Application

Fans and blowers often operate according to changing airflow requirements.

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

When the process requires less air, the motor can operate at a lower speed.

When greater airflow is needed, the motor speed can be increased.

This provides a flexible operating method for industrial ventilation and process-air systems.

---

37. Practical Mixer Application

Mixing equipment can require several different operating speeds.

For example, a production process may use:

1. Low-speed loading.
2. Medium-speed mixing.
3. Higher-speed processing.
4. Controlled deceleration.

The drive can provide these different operating conditions through programmable speed control.

This can eliminate the need for frequent mechanical speed changes.

---

38. Practical Material-Handling Application

Material-handling systems often require controlled movement.

A sudden start can cause material to shift.

A sudden stop can create unnecessary mechanical forces.

The drive can provide controlled acceleration and deceleration.

This can improve the smoothness of material movement and reduce mechanical stress.

---
