Refers to a configuration whereby the output variable (e.g. velocity) is not dependent on the load, but only on the target value. A distinction is made between:
- exact position-dependent locking process (positive-lock), in which the input and output variables run in sync (e.g. electric synchronous motor or mechanical linkages);
- estimated position-dependent locking process, in which there is a certain slip between the input and output variables, which causes a slight change to the output variable (e.g. electric motor in parallel circuit or hydraulic drives due to leakage).
