---

2. Brand and Product Series

The PowerFlex 755 series is intended for industrial applications where a motor needs to operate at different speeds or where the machine requires controlled acceleration, deceleration, torque control, process regulation, or integration with an automation system.

---

3. Detailed Technical Parameters

The dimensions and weight should be treated as practical reference values for product planning rather than a substitute for the mechanical drawing of the exact production configuration.

For cabinet design, additional space should be provided for cable routing, terminal access, ventilation, maintenance, and heat dissipation.

---

4. Electrical Characteristics

The 20G11RC015AA0NNNNN is designed for a 400 V AC three-phase system.

Its normal-duty current rating is approximately 15.4 A.

This corresponds to a normal-duty motor capacity of approximately 7.5 kW.

For heavy-duty applications, the drive is rated at approximately 5.5 kW.

This distinction is important because motor applications do not all have the same load characteristics.

A fan or pump may have a relatively different overload requirement from a conveyor, mixer, hoist, or other constant-torque machine.

Therefore, the motor should be selected according to both its rated current and its actual operating duty.

---

5. Normal-Duty and Heavy-Duty Ratings

The normal-duty rating is generally more suitable for applications where the motor load has relatively moderate overload requirements.

The heavy-duty rating is more appropriate for applications where the motor may experience higher torque demand or more severe overload conditions.

The actual drive selection should always be based on the motor nameplate current and application duty rather than horsepower alone.

---

6. Mechanical Specifications

The mechanical characteristics of the drive are important when installing the unit into an existing control cabinet or designing a new electrical panel.

The cabinet should not be designed using only the physical dimensions of the drive body.

Space should also be reserved around the drive for:

• Power cables.
• Motor cables.
• Control wiring.
• Communication cables.
• Airflow.
• Maintenance access.
• Terminal access.
• Heat dissipation.

---

7. Product Introduction

The 20G11RC015AA0NNNNN is designed to provide controlled electrical power to an AC motor.

A conventional motor starter normally provides basic starting and stopping functions. A variable frequency drive provides much greater control.

The drive can regulate motor speed by changing the frequency of the output power.

This means that a motor can operate at a lower speed when production demand is low and increase speed when greater production capacity is required.

This principle is particularly useful for pumps, fans, conveyors, blowers, and processing equipment.

The drive can also provide controlled acceleration and deceleration.

Instead of applying the full electrical supply directly to the motor and allowing the motor to accelerate rapidly, the drive can use a programmed acceleration profile.

This can reduce mechanical shock and provide smoother equipment operation.

---

8. How the Drive Works

The drive receives incoming three-phase AC power and converts it into controlled electrical power for the motor.

The basic operating process can be understood in three stages.

Stage 1 — AC Input

The drive receives three-phase AC power from the electrical distribution system.

The input voltage for this model belongs to the 400 V AC class.

---

Stage 2 — Power Conversion

The incoming electrical power is processed by the drive’s internal power electronics.

The drive controls the electrical characteristics of the output according to the programmed motor parameters and operating command.

---

Stage 3 — Controlled Motor Output

The drive supplies controlled three-phase AC power to the motor.

By changing output frequency and voltage, the drive can control motor speed and operating characteristics.

This allows the same motor to operate at different speeds according to the requirements of the machine.
