A safety system of an elevator provided herein may comprise a safety controller, a sensor unit configured to generate a first sensor signal indicating a travelling parameter and to provide the first sensor signal to an elevator drive unit of the elevator, and a signal converter connected to the sensor unit and configured to convert the first sensor signal into a second signal in a second format compatible with the safety controller and to provide the second signal in the second format to the safety controller. The safety controller may be configured to receive the second signal in the second format and to determine, based on the second signal, if there is an emergency condition.
