功能
安全方向（SDI）
SDI功能可确保驱动器只能移动
S.elected direction.
Effect
Deviation from the direction of motion currently being monitored
is detected reliably and the configured drive-integrated fault
反应已启动。可以选择哪个方向
rotation is to be monitored.
应用
当驱动器只能在一个移动时使用SDI函数
direction. A typical application is to permit the operator access
T.o a danger zone, as long as the machine is rotating in the safe
方向，即远离运营商。在这个状态下，运营商
可以将材料送入工作区/取出材料
工作区没有危险。
Customer benefits
The function saves the use of external components such as speed
监视器和相关接线。释放危险区域
while the machine is moving away from the operator increases
productivity. Without the SDI function, the machine must be safely
S.T.opped during material loading and removal.
Safely-Limited Position (SLP)
The SLP function monitors the axis to ensure that it remains
within the permissible traversing range.
Effect
When SLP is activated, the traversing range limited by the
configured software limit switches is safely monitored. If the
允许遍历遍历范围，可配置的故障
reaction occurs. It is possible to toggle between two traversing
范围，即使机器正在运行。
应用
SLP.is used for applications in which machine operators have to
enter a protection area, e.g. for feeding in and removing material.
安全监控轴位置确保轴不能
进入为运营商而释放的保护区
例如，他们处于危险之中，在存储和检索机上，
龙门起重机或加工中心。
Customer benefits
SLP.can be used for highly-effective protection area monitoring.
The function does away with the use of external components
如硬件限位开关和相关接线
束缚。由于限制过冲后的反应时间短，
可以减少安全间隙。
