The above note is the best place to start from
I have taken the document from post 2/24/2016 5:20 PM and used a mark-up tool to add commentary and placed in into my old post of 2/25/2016 10:24 PM. I do this reluctantly as I know we (you) are moving in the wrong path. ... I agreed with From your supplied link.. (also works up to 27Vdc?) ...this requires for each direction of movement

{Set :: Mentor tone} We program because of the hardware and to compliment it. Case in point... PWM vs PTO when using the H-bridge. Step0 - understand what is asked by the project and what the aims are. Step1 - get to know the hardware and what is required. It does not need to be experimentally proven but it must be 99.5% sure from research at least. - - - in the actual hardware you are using. Step2 - configure the hardware on the PLC. Step3 - create a model (design) of rule based or mathematical formula to give control. Step4 - coding Step5 - test, evaluate, adapt. w PWM links to look at.. |
