The position controller is enabled by an AND link of the binector inputs p2549 (position
controller 1 enable) and p2550 (position controller 2 enable).
The position setpoint filter (p2533 time constant position setpoint filter) is a PT1 element, the
symmetrizing filter as dead time element (p2535 symmetrizing filter speed precontrol (dead
time) and PT1 element (p2536 symmetrizing filter speed precontrol (PT1)). The speed
precontrol p2534 (factor, speed precontrol) can be disabled via the value 0.
Features
● Symmetrization (p2535, p2536)
● Limiting (p2540, p2541)
● Precontrol (p2534)
● Adaptation (p2537, p2538)
Note
We only recommend that experts use the position controller functions without using the basic
positioner.
