Amatrol’s eLearning curriculum is unique in that it thoughtfully combines in-depth theoretical knowledge with practical, hands-on skills. This powerful combination of knowledge and skills solidifies understanding and creates a strong foundation for pursuing more advanced skills.

For example, the AC Variable Frequency Drive eLearning course covers important topics, such as:

Introduction to AC Variable Frequency Drives

Learners begin with an introduction to AC variable frequency drives, including variable speed AC drive basics, two- and three-wire control, and jogging control. Individual lessons focus on topics like the function and operation of two common types of variable speed AC drive, advantages of starting a motor with an AC drive instead of line starting, the external control capabilities of a variable AC drive, and how motor jogging is accomplished with a variable frequency AC drive. Learners will also practice skills, such as operating a motor using the program keypad of a VFD, operating a three-wire control circuit using a variable frequency AC drive, programming a two-wire control circuit, and programming, connecting and operating a variable frequency AC drive for motor jogging.

AC Variable Drives – Speed and Torque Control

In this module, learners will learn control techniques of AC variable frequency drives, including basic speed control, advanced speed control, and torque control. Individual lessons focus on topics like how frequency affects the speed on an AC induction motor, effects of reflected wave voltage, how to program a variable frequency AC drive for multiple speed selections, and understanding Volts per Hertz ratio. Learners will also practice skills, such as control motor speed using the keypad of a variable frequency AC drive, programming and operating a variable frequency AC drive using preset speeds, calculating Volts per Hertz ratio, and programming and operating a variable frequency AC drive to provide low speed boosts.

AC Variable Frequency Drives – Acceleration, Deceleration, and Braking

To finish up Amatrol’s AC Motor Drives eLearning curriculum, the final module focuses on the acceleration, deceleration, and braking of AC variable frequency drives. Individual lessons focus on topics like the importance of ramping, how a variable frequency AC drive can accelerate a motor past its rated speed, and DC injection braking using a variable frequency AC drive. Learners will also practice skills, such as programming and operating a variable frequency AC drive to ramp a motor to stop, programming and operating a variable frequency AC drive to provide S-curve acceleration, and programming and operating a variable frequency AC drive to provide DC injection braking to a motor.
