Configuring notes
To guarantee safe operation, the safety-related brake must be configured on an application-
specific basis.
When doing this, braking torque tolerances, thermal load capacity of the brake, the
speed limits of rotors and active environmental influences must be carefully taken into
consideration.
The safety-related brakes may only be used as a holding brake with emergency stop function.
The brake may only be switched (opened or closed) when it is at a standstill. Emergency
stops are an exception to this rule. A maximum of 2000 emergency stop operations are
permissible over the complete service life of the brake. The brake holding torque must be
used when selecting and dimensioning brakes (M4 torque).
The safety characteristic values of the safety-related brake are applicable under the
precondition that the system is designed so that 80% of the rated brake torque is adequate
for the safety function. This must be carefully ensured when selecting and dimensioning the
brake.
When used in safety-related application, rotors must always be replaced after 10 years.
For technical reasons, the specified rated torques can generally only be reliably achieved after
a brief run-in procedure. The run-in procedure has been completed after applying a braking
energy of 5xW
for the calculation are provided in the configuration notes for the brake provided in Catalog
D50.1.
However, actual torques can deviate from the specified braking torques as a result of
fluctuating properties of the organic friction lining and changing environmental conditions.
These must be taken into account by applying the appropriate safety margins when selecting
and dimensioning the brake. Especially in humid conditions and fluctuating temperatures, an
increased break loose torque can occur after long non-operational periods.
The friction lining must be reactivated at regular intervals if the brake is solely used as
holding brake without any dynamic load being applied. You can achieve this by applying
