11.5 Safe brake control
11
BST safety-related brake module
for control cabinet installation
Features
Brake control for safe disconnection of our electromechanical brake
Advantages
–
Simple installation in the control cabinet on the mounting rail
–
Aligned for safe switching of our brakes
–
The BST as electronic switching element achieves:
-
Wear-free switching off of the brake in normal operation as well as for emergency stop braking
operations
-
Elimination of the consideration of permitted operating cycles, such as for relays
-
Elimination of the contact monitoring (feedback) in the higher-level safe logic, e.g. for relays
-
Elimination of the MTTF
D
calculation due to the confirmation of the characteristic safety value
from SEW-EURODRIVE
–
Status display of the switching status of the brake control directly at the BST
–
TÜV-certified for suitability of the brakes in safety-relevant applications
Voltage supply
The BST is supplied via the DC link of the inverter
