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 com-
pressed 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 module. 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, con-
sult 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 con-
tinuous 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.
