HAL Component — LIMIT3

INSTANTIABLE COMPONENTS — General

All instantiable components can be loaded in two manners

Using loadrt with or without count= | names= parameters as per legacy components
Using newinst, which names the instance and allows further parameters and arguments
primarily pincount= which can set the number of pins created for that instance (where applicable)

NAME

limit3 — 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.

SYNOPSIS

limit3

USAGE SYNOPSIS

loadrt limit3
OR
newinst limit3 <newinstname> [ pincount=N | iprefix=prefix ] [instanceparamX=X | argX=X ]

( args in [ ] denote possible args and parameters, may not be used in all components )

FUNCTIONS

limit3.N.funct ( OR <newinstname>.funct (requires a floating-point thread) )

PINS

limit3.N.in float in ( OR <newinstname>.in float in )

limit3.N.out float out ( OR <newinstname>.out float out )

limit3.N.load bit in ( OR <newinstname>.load bit in ) – When TRUE, immediately set \fBout\fB to \fBin\fR, ignoring maxv and maxa

limit3.N.min float in (default: -1e20) ( OR <newinstname>.min float in (default: -1e20) )

limit3.N.max float in (default: 1e20) ( OR <newinstname>.max float in (default: 1e20) )

limit3.N.maxv float in (default: 1e20) ( OR <newinstname>.maxv float in (default: 1e20) )

limit3.N.maxa float in (default: 1e20) ( OR <newinstname>.maxa float in (default: 1e20) )
