Limiting control
Limiting with continuous output. Limiting control with three-point stepping output can be realized by using a continu -
ous controller with the OVC function. A position controller (three-point stepping) provides override control.

Override control is also possible by means of a classical three-point stepping controller. The positioning signals of the
