Amatrol's variable frequency AC drive eLearning course covers important topics, such as:

Introduction to Variable Frequency AC Drives

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

Speed and Torque Control

Learners will study basic principles of speed and torque control. Individual lessons focus on topics like reflected wave voltage, how to program a VFD, and volts per hertz ratio. Learners will also practice skills, such as connecting and operating a circuit to control motor speed using a variable frequency AC drive, programming and operating a variable frequency AC drive to drive a motor above its base speed, and calculating volts per hertz ratio.

Acceleration, Deceleration, and Braking

Learners using Amatrol’s variable frequency AC drive eLearning course will study basic principles of acceleration, deceleration, and braking. Individual lessons focus on topics like ramping, S-curve acceleration, and DC injection braking. Learners will also practice skills, such as programming and operating a variable frequency AC drive to ramp a motor to a 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.

Fault Diagnostics and Troubleshooting

Learners will study various aspects of fault diagnostics and troubleshooting. Individual lessons focus on topics like fault detection, troubleshooting, and clearing faults. Learners will also practice skills, such as determining faults based on the fault display of a variable frequency AC drive, troubleshooting the parameter settings of a variable frequency AC drive, and manually clearing a fault on a VFD.
