Positioning Operating Mode (Profile Position Mode)
8.3.1
Overview
The structure of this operating mode is evident in Fig. 8.16:
The target position (
target_position
) is passed on to the curve generator. This generates a
nominal position value (
position_demand_value
) for the position controller, which is
described in the
Position Controller
chapter (Position Control Function, chapter 0). These
two function blocks can be set independently of each other.

All input variables of the curve generator are converted with the variables of the factor
group (see chapter 6.3) into the internal units of the regulator. The internal variables are
marked here with an asterisk and are normally not needed by the user.
