1) The specified axial forces are determined by the spring loading and therefore also apply for motors
with holding brake.
Note
Applications with an angular toothed pinion directly on the motor are not permitted with
standard bearings because the permissible axial forces are exceeded.
8.1.11 Available encoders

8.1.12 Brake data
WARNING
Unintentional movements through inadequate braking effect
If you use the holding brake incorrectly, e.g. as a safety brake, or you ignore the number of
permissible operating cycles of the brake, the brake does not close reliably. 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.
