VDI96622
集成安全功能STO（IEC 61800-5-2）允许按照IEC 60204-1进行0类停车
无外部电源接触器。对于0类停机，无需中断电源电压。
这减少了系统成本和响应时间。
0类停止（IEC 60204-1）
在停止类别0（安全扭矩关闭，STO）中，驱动滑行至停止（前提是没有外力
相反操作）。STO安全相关功能旨在帮助防止意外启动，而不是停止电机，因此，根据IEC 60204-1，该功能对应于自动停止。
在存在外部影响的情况下，滑行时间取决于物理
所用部件的特性（如重量、扭矩、摩擦力等），以及其他措施，如
因为可能需要机械制动器来帮助防止任何危险的发生。也就是说，如果
这意味着对您的人员或设备有危险，您必须采取适当的措施。
1类停止（IEC 60204-1）
对于1类停车（安全停车1，SS1），您可以通过控制系统启动受控停车，或
通过使用特定的功能安全相关装置。1类停车是一种受控停车
机器执行器实现停止所需的电源。
由控制/安全相关系统控制的停止既不与安全相关，也不受监控，也不
在断电或检测到错误的情况下，按照规定执行。这必须由
具有安全相关延迟的外部安全相关开关装置。
警告
非预期设备操作
 确保在滑行期间不会对人员或材料造成危险
轴/机器。
 在滑行期间，请勿进入作业区。
 确保在滑行期间，没有其他人可以进入作业区。
 在存在人员和/或设备危险的地方，使用适当的安全联锁装置。
不遵守这些说明可能导致死亡、重伤或设备损坏。

The integrated safety function STO (IEC 61800-5-2) allows for a category 0 stop as per IEC 60204-1 without external power contactors. It is not necessary to interrupt the supply voltage for a category 0 stop. This reduces the system costs and the response times. Category 0 Stop (IEC 60204-1) In stop category 0 (Safe Torque Off, STO), the drive coasts to a stop (provided there are no external forces operating to the contrary). The STO safety-related function is intended to help prevent an unintended startup, not stop a motor, and therefore corresponds to an unassisted stop in accordance with IEC 60204-1. In circumstances where external influences are present, the coast down time depends on physical properties of the components used (such as weight, torque, friction, etc.), and additional measures such as mechanical brakes may be necessary to help prevent any hazard from materializing. That is to say, if this means a hazard to your personnel or equipment, you must take appropriate measures. Category 1 Stop (IEC 60204-1) For stops of category 1 (Safe Stop 1, SS1), you can initiate a controlled stop via the control system, or through the use of specific functional safety-related devices. A Category 1 Stop is a controlled stop with power available to the machine actuators to achieve the stop. The controlled stop by the control/safety-related system is not safety-relevant, nor monitored, and does not perform as defined in the case of a power outage or if an error is detected. This has to be implemented by means of an external safety-related switching device with safety-related delay. WARNING UNINTENDED EQUIPMENT OPERATION  Make certain that no hazards can arise for persons or material during the coast down period of the axis/machine.  Do not enter the zone of operation during the coast down period.  Ensure that no other persons can access the zone of operation during the coast down period.  Use appropriate safety interlocks where personnel and/or equipment hazards exist. Failure to follow these instructions can result in death, serious injury, or equipment damage.
