Safety Integrated
安全停止1（SS1）
SS1功能导致电机快速安全地停止
switches the motor to torque-free mode after coming to a stand-
still, i.e. STO is activated.
激活
SS1功能可以根据符合的安全性停止驱动器
EN 60204-1, Stop Category 1. When the SS1 function is se-
施工，驱动器沿着快速停止坡道自动制动
and automatically activates the Safe Torque Off and Safe Brake
控制功能（如果配置）在参数化安全性时
延迟时间到期。
应用
The SS1 function is used when, in the event of a safety-relevant
incident, the drive must stop as quickly as possible with a sub-
顺序过渡到STO状态（例如紧急停止）。
因此，它用于将大型离心块带到止动件
quickly as possible for the safety of the operating personnel, or
T.o brake motors at high speeds as quickly as possible. Exam-
典型应用的PLE是锯，研磨机旋转 -
Dles，离心者，卷绕机和储存和检索机器。
Customer benefits
The targeted stopping of a drive by means of SS1 reduces the
risk of danger, increases the productivity of a machine, and al-
lows the safety clearances in a machine to be reduced. The prin-
ciple is to bring the drive actively to a standstill, compared with
just using the STO function. Complex mechanical brakes that
易于磨损通常不需要制动
发动机。
安全停止2（SS2）
SS2功能将电机快速带到静止状态
安全性，然后在电机有电机时激活SOS功能
停了下来。
激活
安全停止2功能可以根据安全地安全地停止驱动器
使用EN 60204-1，停止类别2.当SS2功能是SE-时
lected, the drive brakes autonomously along a quick stop ramp.
In contrast to SS1, the drive control remains operational after-
wards, i.e. the motor can supply the full torque required to main-
T.ain zero speed. Standstill is safely monitored (Safe Operating
停止功能）。
应用
与SS1一样，SS2功能可确保最快的替代
celeration of the motor. However, the motor power is not
switched off. Instead, a control system prevents it from leaving
静止位置 - 即使它受到外力的影响。
Typical applications for SS2 include machine tools, for example.
Customer benefits
SS2功能可确保快速轴停止。因为控制
remains active, after the safety function is deselected, produc-
无法在不参考的情况下继续运行。这确保了
短的设置和停滞时间和高productiV.ity.
