Movements Trajectories Used In The Controller - Etel DSC Series Operation & Software Manual

3.1.1

Movements trajectories used in the controller

There are 8 types of movements trajectories available in the controller
Four of them are linear movements:
And four of them are rotary movements:
The Step movement is used by ETEL Tools for the controller & system tuning only (refer to
information).
The S-Curve and Rotary S-Curve movements are used in most applications (refer to §12.10. for more
information).
The Look-up table, infinite rotary, rotary look-up table and calculated movements are used in some
specific applications, by advanced users only (refer to §13.3. for more information).
3.1.1.1 Look-up table movement
The look-up table movements are movements whose trajectories are freely set by the user. It is possible to
save in the controller up to 8 different trajectories.
The look-up table movement's trajectory is kept in a table of 2000 points memorized in a controller, so its
name.
