Abstract
The invention relates to a method for stopping conveying equipment for persons, wherein on response of a safety element a braking process performed by a frequency converter co-operating with a drive motor is initiated, by means of which the conveying equipment for persons is brought to a standstill, wherein the braking process is monitored by a safety circuit which comprises at least a first channel and a second channel. The operational safety of the braking system is thereby increased.
