Product Type: Air-Cooled AC Variable Frequency Drive

---

1. Product Overview

The 20G11RC011JA0NNNNN is a high-performance AC variable frequency drive designed for industrial motor control applications. It belongs to the PowerFlex 755 series, which is part of the broader PowerFlex 750-Series drive platform.

This model is designed to control the speed, acceleration, deceleration, and operating characteristics of three-phase AC motors. Instead of connecting a motor directly to a fixed-frequency electrical supply, the drive regulates the electrical output supplied to the motor, allowing the motor to operate at different speeds according to the actual requirements of the equipment or production process.

The 20G11RC011JA0NNNNN is configured for a 400 V AC three-phase power system and has a nominal output current rating of 11.5 A. It provides a normal-duty power rating of 5.5 kW, while its heavy-duty rating is 4 kW.

The product uses a Frame 1, air-cooled construction and has an IP20 open-type enclosure. It includes an internal dynamic braking transistor, EMC filtering, and an installed common-mode jumper configuration.

This drive is suitable for a wide range of industrial equipment, particularly systems where motor speed must be adjusted during operation. Typical applications include pumps, fans, conveyors, blowers, mixers, packaging equipment, material handling systems, and general manufacturing machinery.

The configuration is supplied without a local HIM keypad, which means that an external or separate operator interface can be selected when local drive configuration or monitoring is required.

4. Detailed Technical Specifications

The exact physical configuration of an industrial drive can vary depending on production revision and installed accessories. For installation and replacement planning, the actual nameplate and physical unit should always be checked before final mechanical design.

---

5. Mechanical Dimensions and Weight

The physical size of the drive is an important consideration when designing an electrical cabinet or replacing an existing motor drive.

The approximate mechanical specifications are shown below.

During panel design, additional space should be reserved for cable entry, power connections, control wiring, ventilation, inspection, and maintenance.

The drive should not be installed without considering airflow around the unit. Inadequate cooling can increase the operating temperature of the drive and may reduce the reliability of the overall system.

---

6. Product Introduction

The 20G11RC011JA0NNNNN is designed to provide adjustable control of three-phase AC motors.

In a conventional motor system, an AC motor connected directly to the electrical supply normally operates at a relatively fixed speed determined by the supply frequency and the design of the motor.

This type of operation is suitable for simple applications, but many industrial processes require more flexibility.

For example, a pump may need to provide different flow rates at different times.

A conveyor may need to operate slowly during setup and more quickly during normal production.

A ventilation system may need to reduce airflow when production demand decreases.

A mixing system may require different operating speeds during different stages of processing.

The PowerFlex 755 drive provides a practical solution by regulating the electrical output delivered to the motor.

By adjusting the output frequency, the drive changes the motor speed.

By adjusting the acceleration and deceleration settings, the drive can also provide smoother machine operation.

7. Main Motor Control Functions

7.1 Variable-Speed Control

The primary function of the drive is variable-speed motor control.

The motor speed can be adjusted according to process requirements instead of being limited to one fixed operating speed.

This provides greater flexibility for industrial machinery.

---

7.2 Controlled Acceleration

The drive can increase motor speed gradually according to programmed acceleration parameters.

Controlled acceleration can reduce sudden mechanical stress.

This can help reduce:

• Shock loading.
• Belt stress.
• Gearbox stress.
• Material movement problems.
• Sudden mechanical impacts.

Controlled acceleration is particularly useful in conveyor and material handling applications.

---

7.3 Controlled Deceleration

The drive can control the way a motor slows down.

This provides more predictable stopping behavior than simply disconnecting the motor from the electrical supply.

Controlled deceleration is useful when machinery must stop smoothly or within a defined operating sequence.

---

7.4 Dynamic Braking Capability

The 20G11RC011JA0NNNNN includes an internal dynamic braking transistor.

Dynamic braking can be particularly useful when a motor and its connected mechanical load have significant inertia.

During rapid deceleration, the motor may generate energy.

A correctly designed braking system can manage this energy and support improved stopping performance.

Typical applications include:

• Conveyors.
• Material handling equipment.
• Processing machinery.
• Rotating equipment.
• Equipment requiring frequent stopping.
• Machinery with high mechanical inertia.

---

PID control can be used when motor speed needs to respond automatically to changes in a process variable.

Typical examples include:

• Pressure control.
• Flow control.
• Liquid level control.
• Ventilation control.
• Pump regulation.
• Process air control.

The drive can automatically increase or decrease motor speed based on feedback from the controlled process.
