% % Safety factor of the brake

• The safety factor is calculated from the ratio of the

rated braking torque and the braking torque required.

• The result is limited to 10 and is displayed even if

the value calculated is higher.

• The DSD only checks the dimensioning as holding

brake!

Possible messages:

Rated torque/dimensioning torque < safety factor of
