Abstract
An electropneumatic control system for a pneumatic drive and electropneumatic position controller for the system, wherein a volume flow booster having a bypass valve is downstream of the position controller to increase the air capacity, where the pneumatic drive is run in a new operating mode multiple times at maximum air capacity in a first direction to support an operator in adjusting the bypass valve, and where upon exceeding a specified position, the air capacity is set to zero, an overshoot value of the pneumatic drive is determined and output for the operator on a display such that by varying adjustment of the bypass valve, the operator can find and set an adjustment of the valve having low overshoot such that with an adjustment found in such a manner, the transition behavior of the control system can be significantly improved without additional effort.
