NAME

steptest - Used by Stepconf to allow testing of acceleration and velocity values for an axis.

SYNOPSIS

loadrt steptest [count= N|names=name1[,name2...]]

FUNCTIONS

steptest.N (requires a floating-point thread)

PINS

steptest.N.jog-minus bit in
Drive TRUE to jog the axis in its minus direction
steptest.N.jog-plus bit in
Drive TRUE to jog the axis in its positive direction
steptest.N.run bit in
Drive TRUE to run the axis near its current position_fb with a trapezoidal velocity profile
steptest.N.maxvel float in
Maximum velocity
steptest.N.maxaccel float in
Permitted Acceleration
steptest.N.amplitude float in
Approximate amplitude of positions to command during 'run'
steptest.N.dir s32 in
Direction from central point to test: 0 = both, 1 = positive, 2 = negative
steptest.N.position-cmd float out
 
steptest.N.position-fb float in
 
steptest.N.running bit out
 
steptest.N.run-target float out
 
steptest.N.run-start float out
 
steptest.N.run-low float out
 
steptest.N.run-high float out
 
steptest.N.pause s32 in (default: 0)
pause time for each end of run in seconds

PARAMETERS

steptest.N.epsilon float rw (default: .001)
 
steptest.N.elapsed float r
Current value of the internal timer
