Abstract
A braking method for a passenger transportation system, which system is embodied as an elevator, escalator, or moving walk, is initiated upon the occurrence of a technical problem in the passenger transportation system. An activation signal activates a service brake of the passenger transportation system and an emergency stop is initiated. In addition to the activation of the service brake, the activation signal is immediately fed to a brake control of the passenger transportation system, so that, upon the occurrence of the activation signal, the brake control switches a drive machine of the passenger transportation system into a motor-brake operating mode. The drive machine is only switched by the brake control into a braking-torque-free state when a braking effect of the service brake on moving components of the passenger transportation system is detected and transmitted to the brake control.
