Description
In this course we will be working with the Allen Bradley PowerFlex4 variable frequency drive.You may have heard about VFDs, seen them in operation or you might have even installed one or two yourself. Whatever your experience level is with VFDs this course will give your skills a major boost, especially for the model that we will be working with. Using the quick start manual provided in the course, together we will learn step by step the art of wiring and programming a VFD from scratch!In a nutshell:We start off by pulling our VFD out of the box to familiarise ourselves with it.We then learn how to protect the drive and wire it up to our motor for the first time.Resetting the drive back to it's factory settings is next which will prepare us for our first round of programming.After powering-up our drive we use the keypad controls to fire up our motor and explore some display features.Once we have graduated from the keypad controls we will learn all about remote control wiring.Gradually adding levels of complexity to our installation we move onto using the relay outputs and analog inputs.We then explore some advanced wiring and programming concepts with plenty of demonstrations.To bring it home we look at possible fault situations and the fault codes that relate.In detail we will learn:Power wiringGeneral precautionsKeypad operationMotor parameter entryStart source, stop mode and speed reference2-wire, 3-wire and potentiometer controlRamp time adjustmentRelay output wiring and selector programmingSINK vs SOURCE configurationExternal supply controlMultiple preset frequency output0-10volt and 4-20ma analog controlElectric brakingPWM output frequencyFlying start Process factorStart boostVoltage band adjustmentFault codesAnd much more.............If you want to get the edge and learn all about VFDs I'll catch you in the course.
Beginner or advanced technicians curious to learn more about VFDs and motor control,Anyone wanting to learn how to connect a VFD to a motor,Anyone wanting to learn how to program a VFD from scratch,Anyone interested in learning how to wire up the digital or analog control inputs of a VFD,Anyone curious about how VFDs control motors
