ok you seem to have found a solution if you say it works ..well done best of luck

ok ...show me the code and show me where you have declared the variables... ascending order of what ....the actual AD channel or the value coming from the channel... is this an actual application or is it a learning exercise? if it's the latter then I can point you in a direction if it's the...

ADArray: ARRAY[0..9] OF REAL; ADArray[0] := AD_1; ADArray[1 ] := AD_2; etc does that work? not sure what you want to do but that moves it around ...you can make a loop to store AD values ..but be careful loops in ST chew up the processor. Don't go out of bounds on your array loop and the use...

Array data type An array is a set of data elements of the same type. Basic and user-defined data types, function block types, and classes may be used as array element types. Example: TYPE TArray1: ARRAY[0..9] OF INT := [1,2,3,4,5,6,7,8,9,10]; TArray2: ARRAY[1..2, 1..2] OF USINT := [11,12,21,22]...

No problems...DC drives a great bit of control kit. ..As for the snubber network resetting the values on the temperature controller. That is a bit strange almost suggests that there is some type of feedback to the electronics. If I remember there was some talk about SCR instead of a...

you write a parser...I have written a parser/compiler( the back end ) that converts ladder to c and then used third-party software to convert c to machine code. Unfortunately, I broke the code, I still have it somewhere. I used an LL1 parser ...Writing compilers/parsers is defiantly not for the...

I would guess that the question is related to jolts on the system that you are interpreting as torque/current issues. Usually, on large fans, you use the s curve acceleration as opposed to the trapezoidal acceleration. The trapezoidal acceleration causes a jolt in the system whereas the s curve...

I've heard of perm magnetic motors becoming demagnetized...never seen it. I worked in a power steering manufacturing facility where they used brushless DC motors.,... thousands per day and never saw one. I would think a small experiment would be easy enough to set up...maybe add some heat to...

if the field is strong enough and opposite to the magnet that would demagnetize it. I've seen this effect in magnetizing machines where you feed an item in a particular direction ..it magnetizes,,, then if you feed the item in the opposite way it demagnetizes. Maybe ....lock the rotor and apply...

ok..now I see Well, it can be mechanical or software, those are your two big pictures of the problem... Can you explain that action mechanically...(is there an elastic force being built up that springs it back like that?)... If it can't be explained mechanically then something is going on in the...

ok ...turns back 1 second....sounds like a coding issue Still not very clear ...do you have a video of the issue

I would suggest you take a video of the problem... Then slow it down...I'm not sure if you can post vids on this forum But regardless it might give you a clue... Are you saying that one of the wheels is "skipping" Sounds like a nice project How are you synchronizing the motor...one step is how...

Is that what the Differential gearbox is for? ....sounds like your project just got a whole lot more complicated. Maybe you can adjust wheel speed according to load.....that might be a bit tricky with a stepper motor

yes, I know, sometimes we forget. I think you're doing a fantastic job. Think I might have got the motor down....a bit of a cheat I've put a SISO transfer function for each winding...My DTC doesn't care about the rotor....maybe somebody has a more complete motor model

Thanks, ControlGuy...I didn't mean to sound ungrateful. If all else fails I will look at it more carefully

That looks good ...but my french doesn't go past salt and pepper

yea....I just finished an awful job for Noord stream 2,,,so got some time your welcome by the way there were a few nick nacks in the code....but I assume its work in progress

be careful with the brackets ...depending on the compiler ...it can give some funny results.. ....good practice to end else if with else...I'm guilty of this sin as well

ok....good stuff
