Out of curiosity, what are the benefits of a vfd soft starting a conveyor belt rather than just turning on the motor and having the conveyor run full speed?

@automationdirect 3 года назад

Hi Urano, You really have three options: 1) Line Start (On/OFF), 2. Soft Starter and 3) VFD. And of course, it all depends on your application. *Line Start:* There is nothing wrong with Line Start BUT, it does increase the stress on your system going straight to full power rather than easing into it and can cause voltage dips on your main lines since a typical AC motor can draw around 6X full rated amperage on startup. We have a whole bunch of videos showing you how to do this here: www.AutomationDirect.com/Cookbook - look for the "A/C Motors: On/OFF chapter. *Soft Starter:* An economical and easy way to ease a motor up to full speed and reduce inrush current. Search the AutomationDirect website for more info on those. We have a number of videos on those too at www.automationdirect.com/videos - search for "soft starter" *VFD:* Same benefits as Soft Starter, but can do LOTs more including running motor above 60Hz, reverse the motor, and some even have PLCs built in. We have TONs of tutorial videos on VFDs here: www.AutomationDirect.com/Cookbook - look for the "A/C Motors Drive" chapter.

Thanks, that was a great explanation. We are getting error code F021 and F022 on our WEG cfw300. We are running a three phase 1.1kw 220v Electric Motor with it that turns a plastic extrusion screw to recycle plastic here on the island. The input power comes from a big single phase generator that powers the island that we are on. Since we get both under and overvoltage, am I guessing correctly that this has more to do with the fluctuation power supply aka the generator not spitting out pure sine wave power and / or other people plugging stuff in at the same time possibly? Thanks a bunch for your help, it’s highly appreciated. Cheers, Nike #inmoceanforcleanoceans

Thanks for the feedback. Yes, it does sound like you have a supply issue. Are you using the WPS software to configure the drive? If so, then there are some awesome debug and diagnostic capabilities in there that will show you what is going on inside the drive and help you isolate the issue. The software is free (download at AutomationDirect.com), but you will need an optional com module to communicate with the drive. Check out these videos to get started with WPS: WPS Quick Start: www.automationdirect.com/videos/video?videoToPlay=E4EqEJ_m99M&q=wps WPS Diagnostics and Wizards: www.automationdirect.com/videos/video?videoToPlay=e8FIgTNn9bA&q=wps And hopefully you know that we have over 1200 automation videos at: www.automationdirect.com/videos And that there is a "video cookbook" with a whole chapter dedicated to VFDs here: www.automationdirect.com/cookbook

@@automationdirect thanks so much for ur reply! No, we are not using the software 😬 but I will look into it and look at some more of ur videos to understand it all a bit better. Thanks so much for your answer. I guess we will have to find a way to regulate the incoming power from the generator before it reaches the cfw300 then...👍

@automationdirect 3 года назад

@@WhiteSpotPirates Keep in mind, the software just shows you the results in a nice clean graphical environment. You can still see all of that stuff via the parameters. So, yes, watch the videos for hints - especially the videos on under and over voltage. Good luck!

@WhiteSpotPirates 3 года назад

@@automationdirect thank you! Someone recommended to use a voltage regulator before the power hits the cfw300. Do you think that would help with the fluctuating current? Or would h recommend a different device? I was wondering to transform 220v to 12v and then use a sine wave inverter to get clean power, but that’s more pricy than the voltage regulator and probably not necessary? I live on a sailboat , so I am more familiar working with 12 v DC than AC, so trying to figure out how things work 😂

@automationdirect 3 года назад

@@WhiteSpotPirates I'll ask our engineers for suggestions. Standby ... (Please verify: The "Big Generator" is providing single phase 220VC - correct?

@locutusv1 5 лет назад

This usually happens to cheap inexpensive drives

@automationdirect 5 лет назад

Actually, this can happen to any drive - it's good stuff to know!

It happens in my company whete I work. VSD drives 650KW motor that's connected to gigantic fan and every now and then it comes up with overvoltage explained in this video. VSD is 2 meters tall by 600mm wide and costs 100K.
