功能
Safe Brake Control (SBC)
The SBC function permits the safe control of a holding brake.
SBC始终与STO并行激活。
效果
A holding brake which is active in a de-energized state is con-
T.rolled and monitored using safe two-channel technology. Due to
T.he two-channel control, the brake may still be activated in the
控制电缆中保温故障的事件。这类错误
通过测试脉冲提前检测到。
笔记：
安全制动控制不会检测制动器中的机械故障
itself, such as worn brake linings. For Motor Modules in booksize
格式，电机制动器的端子集成在一起。一个addi-
T.ional Safe Brake Relay is required for Power Modules in blocksize
格式。电源需要额外的安全制动适配器
M.odules in chassis format.
应用
SBC功能与STO功能结合使用
or SS1 to prevent the movement of an axis in the torque-free
国家，例如因为重力。
Customer benefits
同样，该功能可节省外部硬件的使用和
associated wiring.
Safe Brake Test (SBT)
SBT诊断功能执行制动功能测试
regular intervals or before personnel enter the danger zone.
效果
A good way to check the proper functioning of brakes that have
变得佩戴是将扭矩施加到封闭的制动器上。驾驶
S.ystems that have two brakes, e.g. motor brake and external
brake, can be tested with different torque values.
应用
SBT诊断功能适用于实施安全
brake in combination with the SBC function.
Customer benefits
该功能检测制动力学中的故障或磨损。
Automatically testing the effectiveness of brakes reduces
维护成本并提高安全性和可用性
of the machine or plant.
