i have dolly which travels on tracks , engine have hall sensor ,
and im geting proper velues on roborun utility , forward positive count , reverse negative hall counts,
controlling motor via analog joystick ( potentiometer) , engine spins and stops properly,

what i need is to set travel limits minimum and maximum,
i set minimum hall count and maximum hall count and any action for example Estop, but engine just goes by that count.

I'm in open speed mode, do i need to do this in close loop?

Try using as action Forward Limit Switch and Reverse Limit Switch and let us know if it works.

hii

so i tried forward/reverse limit switch and nothing, different hall values.

in roborun utility there is selecting feedback for close loop but for open loop its nothing there, so maybe that the problem,
i think hall sensor must be on the left too in input/output tab, so you can select/feedback or motor command

when i set forward / reverse limit switch on analog input
and trigger it with potentiometer it works perfect - stops as needed.

with hall counter no reaction

and when i set speed/acceleration max speed rpm , its no reaction either motor spins ignoring that limitation

acceleration and deceleration works fine

thanks

now it works engine stops on set hall counter value

one more question .

i need that engine stoping was smooth not hard , do i need to set action to ( run script ) and write script to start deceleration till stop or there is easier way ?

and what i found strange, in run window serial is not on mute , and analog input is disabled , but if you go to configuration window analog input starts working,
quite strange,????
because if i want to recalibrate potentiometer,
i start calibration and motor starts spining, so you need to be careful with analog inputs in configuration screen even if its not active in run window ,

or its a bug ?
