20. Motion functions concepts
This is a series of software functions for the EC-4 board that can meet all modern application
needs. The main characteristics are shown below.
Speed mode Used to generate a position profile that allows you to control the speed of the
motor with the programmed acceleration limits. More than one position profile can be
active at the same time.
Positioner Enables incremental or absolute positioning where all positioning parameters
can be changed dynamically during the execution of the profile itself. More than one
position profile can be active at the same time.
Electrical shaft Used to carry out the electrical shaft function. The master/slave
relationship and the engage/disengage mode are programmable. It is possible to engage
without phase recovery. With phase recovery, post- and pre-trigger functions are also
available. Disengaging can be on command, automatic by module, or on command and by
module.
Electronic cam Provides the functions of an electronic cam. The cam profile
can be open or closed, continuous or by individual module. The cam profile can also be
changed dynamically. The cam is described with a table of any length, and more than one
cam profile can exist. The cam profile can also be described in polynomial form, and
between point pairs a cubic spline interpolation can be done.
Each profile generator can be summed with another or used as input of another, resulting in a
series of virtual axes.
