Information
If an emergency evacuation is carried out by opening the brakes, the motor windings should be short-
circuited for the evacuation to prevent an uncontrolled acceleration of the elevator. The short-circuit
generates a speed-dependent braking torque, sufficient in most cases to reduce the elevator speed to
a safe level.
CAUTION!
If operating with synchronous motors from other manufacturers, you have to ensure that a manually
emergency evacuation is approved.
