Abstract
A method and system for controlling an actuator, in particular an actuator of a winch, a hoist or a crane, wherein the actuator is controlled using a fail-safe control unit. In order to improve a corresponding method, according to the invention, set point values are calculated in the fail-safe control unit, on the basis of which values the actuator is controlled.

A method for controlling an actuator of a winch, a hoist or a crane via a fail-safe control unit, wherein said method comprises:
- calculating desired values in the fail-safe control unit based on which the actuator is controlled;
- determining actual values via a sensor system comprising a single position measuring sensor or speed sensor;
- and
- monitoring the actuator via the fail-safe control unit by comparing the desired values to the actual values;
- wherein the actual values are fed back to the fail-safe control unit via a single hardware channel of the sensor system that connects the actuator to the fail-safe control unit.
A method for controlling an actuator of a winch, a hoist or a crane via a fail-safe control unit, wherein said method comprises:
- calculating desired values in the fail-safe control unit based on which the actuator is controlled;
- determining actual values via a sensor system comprising a single position measuring sensor or speed sensor;
- and
- monitoring the actuator via the fail-safe control unit by encoder-less monitoring.
A system for controlling and monitoring an actuator of a winch, a hoist or a crane, said system comprising:
- an actuator;
- and
- a fail-safe control unit;
- wherein the actuator can be controlled and monitored via the fail-safe control unit according to the method of claim 1.
