Configuring MPG parameters was created by aleksamc
I would like to use MPG and to configure such function:
MPG has x1, x10 x100 outputs.
I want to use them for "max_velocity_override"
If x10 is anabled than "setp mvoincr.in01 30% of speed"
If x100 is anabled than "setp mvoincr.in02 100% of speed"
I realize it with such code
But what I should do with this part of code to directly write this value to maximum velocity?
I have such code generated with PncConf. I don't have possibility now to check how it works.
Is this right?
PS
I think that "max-vel-override" defines the speed that machine moves in G00 mode. Is it true?

net max-vel-override-incr => halui.max-velocity.counts
net jog-incr-a => mvoincr.sel0
net jog-incr-b => mvoincr.sel1
net max-vel-override-incr <= mvoincr.out-s
setp mvoincr.debounce-time 0.200000
setp mvoincr.use-graycode False
setp mvoincr.suppress-no-input False
setp mvoincr.in00 5
setp mvoincr.in01 30
setp mvoincr.in02 100But what I should do with this part of code to directly write this value to maximum velocity?

# connect max velocity overide increments - switches
setp halui.max-velocity.count-enable true
setp halui.max-velocity.direct-value true
setp halui.max-velocity.scale 1.0PS

Max velocity sets the overall max speed for all movements (other then homing i'm pretty sure)
If you just want to control rapid feed then rapid override is what you want. - it seems it's missing from the docs...
MPG is a pulse dial (you spin it) - your code looks like you are trying to use switches - maybe rotary switches to set MVO.
If so:
I believe your scale needs to be set to you machine's max possible velocity / 100

I'm going to follow this as I'm the process of wiring up a simple rotary switch to control feed override. I have a and b channel in quadrature mode hooked up to mesa on 2 inputs on the 7i77. Is there a good example of simple code I can copy? I initially tried to connecting a and b as an encoder, not sure if there is an easier way to read it in?

I've checked. Rapid feed don't want to work but max velocity override works fine when program is running.

As for me. I used rapid override for 3p switches 5-30-100% (for example).I'm going to follow this as I'm the process of wiring up a simple rotary switch to control feed override.

aleksamc, thanks for the clarification on the 3 position switch.
I will continue my questions in my original post;

I don't follow what you mean.
Rapid override doesn't override rapid moves or the pins are not available?
They should be available in 2.7

It seems, that they are not available, because I wrote all right.
