Notice
Functionality for different operating conditions
¾
The brakes are dimensioned in such a way that the specified rated torques are reached
safely after a short run-in process.
¾
Since the material properties of the friction linings are subject to fluctuations and as a re-
sult of different environmental conditions, deviations from the specified braking torque are
possible. This has to be taken into account by appropriate dimensioning of the tolerances.
Increased breakaway torque can occur in particular as an result of long standstill periods in
humid environments with varying temperatures.
7.2
Function checks before initial commissioning
DANGER
Danger: rotating parts!
¾
The brake must be free of residual torque.
¾
The drive must not be running when checking the brake.
DANGER
There is a risk of injury by electrical shock!
The live connections must not be touched.
7.2.1
Function check of the brake
If a fault or malfunction arises during the function check, you can find important information for trou-
bleshooting in the chapter Troubleshooting and fault elimination, Page 48. If the fault cannot be fixed or
eliminated, please contact the customer service department.
7.2.2
Release / voltage control
1. Switch off the supply to the motor and brake securely.
2. When switching on the brake supply, make sure that the motor DOES NOT start up (e.g. remove the
two bridges on the motor terminals).
–
Do not
disconnect the supply connections to the brake.
– If the rectifier for the brake supply is connected to the neutral point of the motor,
also
connect the
neutral conductor to this connection.
DANGER
Danger: rotating parts!
Your system should be mechanically immobilized in the event that it could start moving
when the brake is released.
3. Switch the power on.
