Does anybody know of a way to reduce the spindle acceleration/deceleration rates on M560v - OSP300 control?

The simpliest way is multiple lines changing spindle speed.
instead of S8000
use
S80M3
S100
S120
S140
and so on ...

hello blurrycustoms

i have recently delivered a code for custom spindle acceleration, smooth little variable steps, sinusoidal jerk, data log, and single-block ignore

default acceleration rate is too high, and it was needed to clamp heavy parts, like 1000, 1500 kg, etc

if you wish, check attached progress : is not a must to read them thgough, i only shared to highlight that research had been done, and fully tested

please feel free to ask anything

i can help with code, posprocess automatization ( regardless of cam software ), implementation, etc there are 5 inputs for the code are : target rpm, gear, direction, delay(droop), and maximum step, but those can be shortened to one single input (like only target rpm ), by placing all other variables "under-the-hood"

The simpliest way is multiple lines changing spindle speed.
instead of S8000
use
S80M3
S100
S120
S140
and so on

such code creates shocks, is not smooth, and steps have to be adjusted, because going from 200 to 300 is different than from 7000 to 7100, from machine behaviour, even if step is the same ( 100rpm ); so such a thing can be considered, and i have controlled it, because it was requested / kindly
