5. Mechanical Dimensions and Installation Data

The physical dimensions of the drive are an important consideration when designing or modifying an industrial control panel.

The approximate mechanical dimensions are shown below.

The actual control cabinet should provide sufficient installation clearance around the drive.

Adequate spacing is important because the drive generates heat during normal operation. The surrounding panel layout should also allow access for wiring, maintenance, inspection, and replacement.

6. Product Introduction

The 20G11NE6P1AA0NNNNN is designed to provide adjustable-speed control for three-phase AC motors.

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

In many industrial applications, however, operating continuously at a fixed speed is not the most efficient or practical solution.

For example, a pump may require different flow rates throughout the day.

A conveyor may need to operate at different speeds depending on production requirements.

A fan may need to reduce its speed when the required airflow decreases.

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

The PowerFlex 755 drive addresses these requirements by converting the incoming AC electrical supply into a controlled output for the motor.

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

This provides greater flexibility than conventional fixed-speed motor operation.

---

7. Motor Control Function

The drive performs several important functions in an industrial motor system.

Variable Speed Control

The drive can increase or decrease motor speed according to the application requirements.

This makes it suitable for processes where production speed or equipment capacity must be adjusted.

---

Controlled Acceleration

The motor can be accelerated according to a programmed acceleration profile.

Controlled acceleration can reduce sudden mechanical shock on equipment.

This can be particularly useful for conveyor systems and machinery with mechanical transmission components.

---

Controlled Deceleration

The drive can control how quickly the motor slows down.

This is useful when a machine cannot simply stop freely because of mechanical inertia or process requirements.

---

Dynamic Braking Capability

The model includes a dynamic braking transistor.

Dynamic braking is useful when the motor and connected load must decelerate more rapidly.

During certain deceleration conditions, energy generated by the motor must be managed by the drive system.

A properly selected braking arrangement can help improve stopping performance.

---

PID Process Control

The drive supports PID control characteristics.

PID control is commonly used when the drive speed must automatically respond to a process variable.

Typical examples include:

• Pressure control.
• Flow control.
• Liquid level control.
• Temperature-related process control.

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

---
