FUNCTION BLOCKS of basic machine elements
Below you can download example function blocks that can be used to model the behavior of basic device elements.
How to download and install a function block for your own project? (course - part 1, watch the clip from 6:25 min.)
1-axis rotary module with positioner
get function block
application example
function block inputs:
ENABLE - enabling the module operation
DEMAND POS - set position of the module in [deg./sec]
MAX VEL - maximum speed in [deg./sec]
% VEL - movement speed as a% of maximum speed
MAX ALPHA - maximum position of the module in [degrees]
MIN ALPHA - minimum position of the module in [degrees]
RV_no - register number in which the current position of the module is stored.
You must provide this register and it must be different for each linear module in a given project.
FREQ - simulation frequency in [Hz] - frequency should be calculated as the reciprocal of the simulation period, which can be set and checked in the top menu -> settings -> simulation in window. For an exemplary period value of 2000 [microseconds], the frequency value is 500 [Hz], because 1 / (2000 [microseconds]) = 500 [Hz].
function block outputs:
POS ALPHA - current position of the output element of the rotary module
MAX_Limit - limit switch MAX position signal - sensor range: 1 [deg.]
MIN_Limit - limit switch MIN position signal - sensor range: 1 [deg.]
