i start use absolute encoder
if you want to use absolute encoder(i use chines ,every driver this days suport also absolute encoder)you need :
1.read the value from driver(can by etherecat or by rs485 )
2.update mach with the position (this was the hard part becuse even mach have lua function that update the machine cordinate ,its not real work)

Mach4 General Discussion / how reset counter

« on: August 16, 2021, 09:50:53 AM »

i try reset the counter
hreg = mc.mcRegGetHandle(0, "PoKeys_52673/Counter 02")
                  
                  mc.mcRegSetValue(hreg,0)
its real put 0  on counter
but when i start again to count its intiles the old value
also when i shut down even if its show 0 its still remember the old value

steve thanks alot
ill read and test yours advise
i use pokeys ,do you think they analog output suport also -10 or i must add relay to convert polarity for reverse?

in mach4 ,for all that question, you will write the answer(the answer are writen by lua in m6 in yours case or any other m function that you can imagine

this project its retrofit several old Europe cnc ,and that position axiss its only analog ,and i don't want replace the driver+ motor
about timing its not problem i can solve it in some ways,like delay in my action according feedback when close to the final position,also i can do script to learn the decll time so i can be more presize,this not the problem
the problem its very basic simple and i dont understand why any one from mach cant answer,what is command  how control the PMW output
there a tab with it on mach but no any instruction what and how to do

hi craig
i know,but in this case im not care about timing ,because its not axiss that have any interpolation with other axis
its just position device,so i can wait until its reach its position ,and i can slow the motion before i reach the position then stop
but how can i control the PMW without the use of the RPM S3 function i didnt see in any mach document

but after you correct the move,how do you reset the new position ? so mach will know its correct position?

if it so important to you ,connect 2 computers ,its much easy ,one will be supervisor ,so you enev not need 2 screen or 2 keyboard
you can send command to the slave to run directly in mach so user even almos dont know he use second mach

how you correct the position if need? i asked in the past here if there option to modify the machine cordinate but answer was no
only by G52 or similar tool but not real modify the machine cordinate

i think PMC can be the best way
