Elevator control system, comprising an elevator control device for operating an elevator car which is adapted to be operated within an elevator shaft, and an inspection control station configured to communicate with the elevator control device for operating at least one function of an elevator system in an inspection or maintenance operation mode, and configured for attachment at a storing location, wherein the storing location is at the elevator car or within the elevator shaft or in proximity of the elevator shaft. The inspection control station is adapted to be detachable from the storing location and configured to operate as remote inspection control station when detached from the storing location through wireless communication with the elevator control device, and is configured to be movable and operable in the inspection or maintenance operation mode from inside and outside of the elevator car and within the elevator shaft.

An example elevator brake includes a first braking member that is biased by a first spring member into engagement with a braking surface. The first braking member includes a first armature arranged to be actuated by an electromagnetic actuator to disengage the first braking member from the braking surface against the biasing force of the first spring member. A second braking member is biased by a second spring member into engagement with a braking surface. The second braking member includes a second armature arranged to be actuated by an electromagnetic actuator to disengage the second braking member against the biasing force of the second spring member. A first electromagnetic actuator actuates the first armature and a second electromagnetic actuator actuates the second armature.

A control arrangement () for an elevator brake, comprises a control circuit () adapted to generate, according to a demand for releasing a first braking member of the elevator brake, a first actuating signal and to generate, according to a demand for releasing a second braking member of the elevator brake, a second actuating signal; a first terminal () for outputting the first actuating signal to a first electromagnetic actuating means () of the elevator brake, a second terminal for outputting the second actuating signal to a second electromagnetic actuating means () of the elevator brake; the control arrangement () being adapted to allow at least the following modes of operation: A) a normal operation mode in which the first and the second actuating signals are supplied synchronously to the first and second electromagnetic actuation means (), respectively, and B) a single braking member test operation mode, in which one of the first and second actuating signals is supplied to the respective one of the first and second electromagnetic actuating means (), and an actuating signal for permanently releasing the respective of the first and second braking members () is supplied to the other one of the first and second electromagnetic actuating means ().

An elevator system and associated method includes power control for operating an elevator () in an emergency mode wherein the elevator () includes a car (), a drive motor (), a motor drive unit () which supplies power to the drive motor () and controls the same and an emergency power supply (). The motor drive unit () has a predetermined normal operation switching frequency. In an emergency mode, power is supplied to the motor from the emergency power supply () while the motor drive unit is in an emergency mode. An actual emergency operation condition characteristic is determined for setting the switching frequency of the motor drive unit () dependent on the actual emergency operation condition characteristic.
