III-16 Controller
General: Function blocks CONTR and CONTR+ and PIDMA provide a complex control function. Unlike CONTR, CONTR+
includes six selectable control parameter sets. However, PIDMA provides a special control algorithm and different
self-tuning.
In the following sections, the main features of the functionblocks CONTR, CONTR+ together and PIDMA separately are
described. Then the common controltechnical application ranges are explained.
III-16.1 CONTR (Controllerfunction with one parameterset (No. 90))
The CONTR block provides a PID controller with numerous functions such as ramp, internal/external/W2 switchover, /process
value tracking, self-tuning, override control, feed-forward control, positioning signal forcing, ratio and three-element control in 12
different controller types (continuous/2-point/3-point/3-point stepping/ ...).
