sorry never use these features ... but now I'm interested on .... on my hal file try to write these row:
net max-acc <= motion.analog-out-04
net max-acc => ini.x.max_acceleration

Linuxcnc close with error on terminal :  "/mihal.hal:1213: Pin 'ini.X.max_acceleration' does not exist "

And we not see how corret it ... i done some other INI custom parameter and it works ... but I understand "ini.x.max_acceleration" is connecter directly with AXIS section on INI file ....I'm in wrong or need to implement somethings?

i use Lcnc2.9.1

regrds

Did you try this way already?
net max-acc   [JOINT_0] MAX_ACCELERATION

I think he wants to change the 'ini.x.max_acceleration' value after startup.
Note that ini hal pins only exist after the gui has loaded, so you need to put that hal line in the postgui.hal file.

there are a way to modify acceleration during motion? or need to integrate Limit on kinematics and use some float pint to archive these targhet?

I'm sorry, forgot to mention this:

The new ini values will only come into effect after a 'quebuster'. For example after 'M66 E0 L0'.
