Description
The position controller is a PI controller. The P gain can be adapted using the pro-
duct of the connector input p2537 (adaptation position controller) 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-interconnected with
connector output p2540.
The position controller is enabled via binector inputs p2549 (enable position
controller 1) and p2550 (enable position controller 2) that are AND'ed with one
another.
The position setpoint filter (p2533 time constant position setpoint filter) is a PT1
element, the symmetrizing filter as deadtime element (p2535 symmetrizing filter
speed pre-control (deadtime) and PT1 element (p2536 symmetrizing filter speed
pre-control (PT1)). The speed pre-control p2534 (factor, speed pre-control) can be
disabled via the value 0.
