Brake data

The holding brake is used to clamp the motor shaft when the motor is at a standstill. The holding
brake is not a working brake for braking the rotating motor. When the motor is at a standstill, the
holding brake is designed for at least 5 million switching cycles.
Limited EMERGENCY STOP operation is permissible. Take into account the maximum
permissible individual operating energy as well as service life, total operating energy of the
brake.
Unintentional movements through inadequate braking effect
If you use the holding brake incorrectly, e.g. as an operating brake or you ignore the
permissible operating energy of the brake, then the brake will be subject to excessive and
impermissible wear. As a consequence, there may be no brake effect. Unintentional
movements of the machine or system can result in death or serious injury.
● Observe the permissible number of operating cycles and EMERGENCY STOP properties.
● Operate the motor only in conjunction with an intact brake.
● Avoid repeated brief acceleration of the motor against a holding brake that is still closed.
The holding brakes of the 1FK2 have a torsional backlash of less than 1.5°.
The following table lists additional technical data regarding the holding brakes for operation
