9.4.6.2 Position controller
Description
The position controller is a PI controller. The P gain can be adapted using the product of
connector input p2537 (position controller adaptation) and parameter p2538 (Kp).
Using connector input p2541 (limit), the speed setpoint of the position controller can be
limited without pre-control. This connector input is pre-connected with connector output
p2540.
The position controller is enabled using an AND logic operation 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.
Note
Position controller without basic positioner for experts only
We recommend that only experts use the functions of the position controller without using
the basic positioner.
