Morning. I'm doing the same with a 3450 motor where do I find the maximum hz I can push a 2 pole motor to. Or is this just common electrical engineer knowledge.
Hi Aldrich, their are a ton of online resources regarding VFD's and complicated formulas but the simplest rule of thumb is to not exceed more than 90Hz for a non inverter duty motor. You can actually hear the motor become unhappy if you push it to hard for testing. Generally I don't overdrive my motors to much. I try to stay at 60Hz or less and on occasion push to 75Hz. Hope that helps.
@@BurtonsAttic it does. I finally found on engineering.com that you can "push" a 4 pole up to 200% and a 2 pole to 125% or 75 hz I'll just stick with 60hz and be happy with it. Thanks for caring brother. I appreciate your works!
Thanks. By frequency reference I think you mean the Hz display. It is simply the Hz range that you have programmed the parameter for frequency lower and upper limit. The minimum and maximum speed you want the motor to run at. Mine is set at 5Hz to 100Hz (over driven by 40Hz). In a non VFD configuration the motor would just be running at 60 Hz. Hope that helps, if that didn't answer your question LMK.
I read your email, please reply here so others can read. In your current configuration do you have any external input device? Or you just have the potentiometer on the VFD interface? Also here is the link to the online manual, a lot easier to use than the small book that comes with the VFD. www.tecowestinghouse.com/Manuals/L510_instruction_manual.pdf
Slagged the black/output cable is 14/4 meaning it is 14 gauge with 4 conductors/wires which is correct for this particular application. The orange cable is 16/3 which is just a normal extension cord I'm using just for test purposes. In a final installation I would use 14/3 for the input cable or 14/4 and not use one conductor. Yes the orange cable has a 120V plug on it. The VFD turns that 120V into 240V. Almost all cabling for this type of installation is rated for 600V today. Go to your local big box store and look at the electrical cable. This type of cable is on a spool and is sold by the foot. Also it is referred to as multi strand wire/cable.
Andreas in the audio of this video I mention all the parameters that are required for a normal straight forward non industrial application, like just controlling a variable speed motor of some type. Those parameters are pretty much called out the same for all VFD brands. The parameters (PID) are found in the manual that comes with your specific VFD (along with the programming procedure) you just need to gather a little more information about your specific application from the motor data plate. Hope that helps.
Burton's Attic Thank you... yes i listened a few times and cross reference the instructions . Your info was great just my vfd set up was a bit wonky. Got it all sorted. Again thanks.
My dear your demo was not useful, because you showed what you did , mostly they explain step by step for whom to want lear what you are doing , spacialy for wire conection and very important seting up the necessary paramiters,by the way thank you .
