6. Product Introduction

The 20G11RC011AA0NNNNN is designed to control the operation of three-phase AC motors.

In a conventional electrical installation, an AC motor connected directly to the electrical supply normally operates at a speed determined largely by the frequency of the incoming power supply and the characteristics of the motor.

Many industrial processes do not require a motor to operate continuously at one fixed speed.

For example, a pump may require different flow rates during different stages of operation.

A conveyor may need to change its speed depending on production requirements.

A fan may need to reduce its speed when less airflow is required.

A processing machine may need controlled acceleration to prevent sudden mechanical loading.

The PowerFlex 755 drive provides a solution by controlling the electrical frequency and voltage supplied to the motor.

By changing the output frequency, the drive can regulate motor speed.

By controlling acceleration and deceleration parameters, the drive can also improve the operational behavior of the equipment.

---

7. Motor Control Functions

7.1 Variable-Speed Control

The main purpose of the drive is to provide adjustable motor speed.

The output frequency supplied to the motor can be controlled according to the requirements of the application.

This allows a machine to operate at different speeds without requiring mechanical speed-changing equipment.

---

7.2 Controlled Acceleration

The drive can accelerate the motor gradually according to programmed parameters.

Controlled acceleration can help reduce:

• Mechanical shock.
• Sudden load changes.
• Belt stress.
• Gearbox stress.
• Material movement problems.

This is especially useful in conveyor and material handling applications.

---

7.3 Controlled Deceleration

The drive can also control how the motor slows down.

This can provide smoother machine stopping behavior compared with simply disconnecting the motor from the electrical supply.

Controlled deceleration is particularly useful when process equipment must stop in a predictable manner.

---

7.4 Dynamic Braking Capability

The 20G11RC011AA0NNNNN includes an internal dynamic braking transistor.

Dynamic braking can be useful when a motor and connected load must decelerate quickly.

Applications with mechanical inertia may generate electrical energy during deceleration.

A correctly designed braking system can help manage this energy and improve controlled stopping performance.

Typical applications include:

• Conveyors.
• Material handling systems.
• Processing machinery.
• Equipment with rotating inertia.
• Machines requiring faster stopping.
