Hi Andy, If you average a steady state PWM signal (apply a low pass filter) you get a DC voltage. At 0% PWM you get 0V, at 50% PWM you get 1/2 voltage and at 100% PWM you get full voltage and so

Hi All, How do you change the backgroun and the background color on the Mach2 screen layouts. I have looked in the screen editor and screen tweeker and can not seem to locate how to make these

I like it, except I'm clumsy enough that I would be sure to destroy it while sliding something thru the spindle bore. Andy Wander Verrex Corporation

Uploaded to "Bloy2004".... an idea for mounting sensor to Lathe spindle of 3 in 1 machine (Shoptask specific)

Les: Thanks for the explanation-what I still don't understand about it is how the "Sine Wave", which is generated by the "filtering" of the motor, will vary in frequency, if the only thing that is

A VFD creates an approximation of a sine wave by pulse width modulating a high frequency carrier. The carrier frequency is high enough that the motor effecively filters it out, leaving the sine wave.

Of course, by changing the width of the ON pulkse, while the frequency stays the same, the width of the OFF pulse is changed also, in the opposite direction. For example a 50% PWM pulse train will

I can't speak about the intricacies of the VFD, but PWM is Pulse Width Modulation, where the ONLY thing that is varied is the width of the "ON" pulse(not both ON and OFF). This means that the

No, it is the same base frequency. The width of the pulse ( length of time it is high ) determines the energy it can deliver. 80% PWM = 80% of the time it high and 20% is low. Jim

Unless I'm mistaken, (wouldn't be the first time), the way the frequency variation manifests itself is by modulating the pulse width. Pulses shorter and closer together = higher frequency. Please

You may need to try the special driver. I believe there is a .BAT file that will install it. Jim

Of course, VFD means Variable Frequency, so is this actually a PWM signal? I'm so confused... Andy Wander Verrex Corporation

Hi Bill: Sounds like some driver or application is shutting down the timer. I would do a msconfig from the run button and uncheck everything in the startup tab. Then try again. If all else fails,

I would start in your services app and shutdown any services that are not necessary. Possibly change from automatic to manual for those services that can be changed. It sounds as if some apps are

I just downloaded Mach2Mill and tried to configure it. The manual says I should have about 24,600 Hz. My Puse Frequency starts high but goes down to 1100-1200 Hz., the program will keep running

Jeff: there a way to scale in MACH2 between the pulses and the RPM? YEs, Mach2 will scale the input automatically and display RPM. I believe even Mill can do this as long as the index or timing

don't think. Art and others will confirm. But a PWM signal is not a pulse signal. it will be complicated to convert it. Mach2 accept only index pulses. Olivier.

Art Is it possible to access the motor tuning through the ocx and vb6?. I know i can call the motor tuning dialog but there is no way of passing variables or reading variables is there?.Other than
