System Structure

In our example, we use an axis which is operated in position control. The ac‐

tuating variable of the process loop, which is to suppress/compensate unwan‐

ted vibration, is an additive command value to the outermost control loop. In

this case, the parameter "P‑0‑0059, Additive position command value, control‐

ler" consequentially is the target parameter of the actuating variable. In this

case, the command value for process control would be the twofold derived po‐

sition profile which is preset by the external PLC. With infinite stiffness, this

would simultaneously be the ideal acceleration profile at the sensor's point of

installation.
