Hello Art, Can you please post the sequence needed to initialize the OCX Maybe some demo code you used to test the OCX. I can use the OCX in VB without...
I am considering changing my manual Logan lathe to CNC. I am unclear as to how the carrage speed is coordinated with the spindle feed to allow threading. Is...
Note: This machine is one of those 3 in 1 combinations so to switch to lathe should I be setting up a new lathe screen using XY? Sorry that previous post...
I notice that "index pulse" can be checked on the parallel input to pick up the true speed of a machine. Can the PWM frequency of a VFD be used for this? If...
John: To use the index input you must be using a *.lset screen layout. It is not good enough to rename Y to Z, you must use Z properly. You'll know if the...
Hi Jeff: The spindle control for speed is not a necissity for threading, a manual speed control will work fine. The only prerequisite for threading is a sensor...
... I noticed that. Does that mean they can't be got? Or does it mean there will be a long lead time? Or maybe you have to buy 10,000 of them? I've found...
You are wrong, it is the opposite. It has been collectively decided for the first mach2 threading implementation that carriage moves need to be slave of the...
Not enough precision for threading. Even if you could do a PWM to pulse convertor it will not work. You will need a true encoder, home made or not. More, it...
Olivier: Actually, this question revolved around my Bridgeport mill. In this case I'd like to get "feedback" to MACH2 and to a readout of RPM, but I don't...

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...
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. ...
... 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...
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...
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...
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...
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...
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. ...
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...
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...
