8. Product Introduction

The 20G11ND5P0AA0NNNNN is intended to provide controlled operation of industrial three-phase AC motors.

A conventional motor starter normally provides basic start and stop functions. An industrial variable frequency drive provides a much broader range of control.

The drive can control the motor during starting, acceleration, normal operation, speed changes and stopping.

This makes it useful for machines where the motor needs to follow a production process rather than simply operate at a fixed speed.

For example, a conveyor may need to run at different speeds depending on the production stage.

A pump may need to maintain a particular process flow.

A fan may need to change speed according to ventilation demand.

A processing machine may require different motor speeds for different production steps.

In these situations, variable-frequency control provides a more flexible solution than fixed-speed operation.

---
