Limited EMERGENCY STOP operation is permissible. Take into account the maximum
permissible single operating energy as w
ell as service life, total operating energy of the
brake.
WARNING
Unintentional movements through inadequate braking e󹪜ect
If you use t
he holding brake incorrectly, for example, 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 e󹪜ect. 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 1FL2 have a torsional backlash of less than 1°.
