limit3 − Follow input signal while obeying limits

Limit the output signal to fall between min and max, limit its slew rate to less than maxv per second, and limit its second derivative to less than maxa per second squared. When the signal is a position, this means that the position, velocity, and acceleration are limited.

**limit3.***N*
(requires a floating-point thread)

**limit3.***N***.in**
float in

limit3.*N***.out** float out

limit3.*N***.load** bit in (default:
*0*)

When TRUE, immediately set
**out to in**, ignoring maxv and maxa

**limit3.***N***.min**
float in (default: *-1e20*)

limit3.*N***.max** float in (default:
*1e20*)

limit3.*N***.maxv** float in (default:
*1e20*)

limit3.*N***.maxa** float in (default:
*1e20*)

limit3.*N***.smooth-steps** u32 in (default:
*2*)

Smooth out acceleration this many periods before reaching input or max/min limit. Higher values avoid oscillation, but will accelerate slightly more slowly.
