17.9 Service brake, holding brake with safety function

The dimensioning of the electromechanical brake on the motor shaft is carried out according to the

required holding torque of the application as a pure "holding brake" at standstill.

• The function of the brake as "service brake", i. e. the cyclic stopping of the rotating motor shaft

from full speed under normal operating conditions is not checked by the DSD.

• The requirement for a holding brake with safety function also recurringly used for emergency-

off purposes for controlled and uncontrolled drives, is not checked by the DSD..

• For these functions, in addition to the torque check, further dimensioning steps are required ad-

ditionally, which are to be gathered from the brake catalogues.

 Note!

Only relevant for motors that are repeatedly stopped from full speed via the electrome-

chanical motor brake!

As a general rule, these are motors directly connected to the mains in start-stop opera-

tion, or brakes in variable-speed drives for emergency-off processes,which are activated

more frequently!
