7.11 Replacing the holding brake
WARNING
The pneumatic holding brake is not a safety component.
The pneumatic holding brake prevents the guide rail from moving
with respect to the guided slides when a force less than 150 N
per brake is applied to the guide (braking effect when new).
In normal operation the braking effect is released by compressed
air and a spring assembly applies the brake when required. Note
that the braking effect is immediately released when the
compressed air supply is switched on, and this can lead to
dangerous movements.
•
The slide or guide rail must not be moved when the brakes are
applied. This can damage the product. This especially reduces
the braking effect
•
The braking effect is also influenced by worn or dirty brake
surfaces. Observing the braking effect and if it decreases,
consult our service department for advice.
•
Make sure the holding brake is integrated sensibly into the
servo controlled concept of the automated system. Note that
this is a stationary holding brake and is not suitable for
continuous operation.
WARNING
Risk of injury when opening the brake cover!
Switch off the control unit and compressed air!
The brake piston is pre-loaded with disk springs.
