DANGER Carry out electrical connection only in
de-energised condition.
Electrical shock possible.
Only trained personnel should carry out
the connection.

10 Initial Operation
10.1 Definition of the Braking Torques
10.1.1 Static braking torque
Effectively averaged, fully developed torque for slipping
brake with smallest speed values.
Guideline value: n = 3 [rpm]
10.1.2 Dynamic braking torque
Effectively averaged, fully developed torque in a braking
procedure from the output speed up to standstill.
For correct evaluation, a sufficient slip
time is required (sliding speed between
1 m/s and 10 m/s).
The permitted friction work and speed val-
ues must not be exceeded.
10.2 Run-in Procedure
The stated brake nominal torque (see 5.2.1.1 for details)
is valid for the friction lining pairings in new condition in
standard climate conditions.

If the friction lining pairing requires conditioning, the
brakes may have to be run in during operation.

In case of longer storage or downtime, the brakes
may have to be run in to achieve the specified brak-
ing torque.
10.3 Brake Inspection (Before Initial Opera-
tion)

Braking torque inspection:
Please compare the requested braking torque with the
torque stated on the type tag (10) (see also braking
torque
5.2.1.1 for details).

Release function inspection:
by energizing the brake.
10.4 Brake Test (initial operation)
CAUTION
During the Brake Test danger to per-
sonnel and damage to machines can-
not be ruled out in case of malfunc-
tions (incorrect installation, control er-
rors etc.). Risks to personnel and ma-
chine damage cannot be ruled out.
Do not enter the danger zone.
Possibly take measures for catching or
damping the load
The brake test is used to inspect the braking torque, and
must be carried out cyclically depending on the applica-
tion. This is to be defined by the customer.
To avoid wear on the brake, the brake test must be con-
ducted so that the motor builds up torque slowly against
the closed brake up to the lower tolerance limit of the
braking torque.
See the document “Hinweise und
Empfehlungen zum statischen Brem-
sentest” (Remarks and suggestions re-
garding static brake tests) on our website

If the rotor (4) is pulled through at this torque, regenera-
tion of the friction linings is necessary.
The regeneration of the friction linings is an independent
procedure.
