How Does a VFD Work? Now that we have established what they are and what problem they solve, how exactly do VFDs perform their intended job? We know that in order to control the motor rotation, we must reduce the speed at which the current is alternated (flipped directions) as it goes...
To answer that question, first, consider how a VFD control panel works. The speed of a motor is controlled in two ways- either by voltage or by frequency. Controlling the speed through frequency is a preferred option because it results in a constant flux density. This is where a VFD comes...
Before uninstalling, try a fresh install on another PC, if you have that option. When I got the VFD, I did all the serial modbus experiments with plain mach3 install on my notebook PC, just to figure how all this works, and then copied relevant settings to the shop PC. If you do ...
That's just how I got it to fail and found a solution that works. Other people may chime in and give a much better explanation. Below is working main.c code. Details are in comments at top of text. BTW, if using KIT-059, be aware there's a 1uF capacitor hanging off P3.2. ...

"It really would be applicable for any customer, but especially for new customers and for sites where they have critical applications, we would go through and test shaft currents and voltages to see if anything's there on a preliminary to gauge how the motor's operating regarding shaft volt...
- Did a fresh installation of Windows XP Pro w/SP3 (so shoot me ... I like it!) <G> - Installed the current version of JRiver MC17 and imported the library and settings from my old machine. Real slick - wondered how well that would work, but it fired right up and it's just ...
In this paper is given a formula derived by the authors, which shows how the design of VFD affects the display performance of VFD. As is shown by the formula, the Q value (the ratio of the total effective area of theapertures in the aperture plate to that of the metal part of the ...
