Yes thats me and my methodics. Now you quoting only that part it looks to me i had a tone, wasnt actually intended, and certainly uncalled for, so very much sry for my tone that just now see, it wasnt about you neither your post really, thats just me being a fart.
Ok, so the final currrent value is the value the current would naturally reach if it would not be interrupted, this final value being given by voltage/coil resistance. For 24v in a 1ohm coil, ohms law sets 24A for a final value, that is the final value the rising current will reach if nothing would happen. And lets say our target(peak) is 2A.
Current rises by a curve that at first the current rises very fast, but at the end it rises very slowly, and will hit the final value but almost tangentially (convergence). The horizontal axis being time, and scale of nanoseconds. For a final value 24A is a high, and the first portion that we will use, will be almost vertically, and our peak of 2A will be hit almost instantly. If we set the final at 6A, then we will have to deal with a slower rise time because now we also have a portion where the current is lazy, and rises slower, so our peak will be hit, but will take longer. This is where and how the final value, e.g. V/R matters. Imo, thats direct control, because in the function V/R is a factor that gets multiplied by the rest of the function, thats mathematically a direct dependency. It seems ohms law has direct control, at least it seems for me tbh, But ofc, that can perhaps be interpreted different ways. The current rises naturally as it wants to, and those are the parameters. We control only the point where the current rise gets interrupted, we do that by adjusting the pot on the driver, and that is the "peak value" i was referring to, i think usually denoted Ipeak or Ilimit.

For example when the final value is lower than our setting. For example 12v and 24ohm resistor, then ohms law gives 0.5A final value, and current cant get higher than that. You can set in controller 1A, but ofc it can not get there - can it.Quote
In what cases does the current not reach the peak value set by the controller?
