安全综合
安全制动测试（SBT）
SBT功能定期执行制动功能测试
intervals.
Activation
检查具有的刹车正常运作的好方法
become worn is to apply a torque to the closed brake. Drive sys-
tems that have two brakes, e.g. motor brake and external brake,
可以用不同的扭矩值进行测试。
Application
SBT功能适用于实施安全制动器
结合SBC功能。
客户福利
The function detects faults or wear in the brake mechanics. Au-
造型测试制动器的有效性降低了维护 -
NANCE成本并提高植物的安全性和可用性/
machines.
Safely-Limited Speed (SLS)
The SLS function ensures that the drive does not exceed a pre-
设置速度限制。
Activation
The SLS function monitors the drive against a parameterized
速度极限。可以选择四个不同的限制值。就像在那样
SO的情况，速度设定值不会独立影响。
After SLS has been selected, the higher-level control must bring
the drive down below the selected speed limit within a parame-
可行的时间。如果超出速度限制，可自定义
drive-integrated fault reaction occurs.
SLS限制阶段1可以乘以变换的因素
通过PROFISAFE以16位分辨率的分辨率。这几乎允许
要指定无限数量的限制。
Application
如果人们处于A的危险区域，则使用SLS函数
machine and their safety can only be guaranteed by reduced
速度。典型的申请案例包括那些操作的申请
erator must enter the danger zone of the machine for the pur-
poses of maintenance or setting up, such as a winder in which
the material is manually threaded by the operator. To prevent in-
jury to the operator, the roller may only spin at a safely reduced
速度。SLS is often also used as part of a two-stage safety con-
cept。虽然一个人处于较少的关键区域，但SLS功能是
激活，驱动器只能在较小的区域中停止
潜在风险较高。SLS不仅可以用于操作员Pro-
切割，但也用于机械保护，例如机械保护。如果是最大值
speed must not be exceeded.
客户福利
The SLS function can contribute to a significant reduction in
downtime, or greatly simplify or even accelerate setup. The over-
all effect achieved is a higher availability of the plant. Moreover,
可以省略诸如速度监视器等外部组件。
