VDI9803
为了避免恢复电源后（例如断电后）电机意外重启，
必须将参数IO\U AutoEnable设置为“off”。
还要验证主控制器不会触发意外重启。
使用安全功能时的防护等级
必须确保导电物质不会进入产品（污染等级2）。导电的
物质可能导致安全功能失效。
受保护电缆安装
如果安全功能STO的信号之间存在短路和其他接线错误，如交叉故障
如果这些短路和交叉故障
上游设备未检测到，需要按照ISO 13849-2安装受保护的电缆。
如果是无保护电缆安装，安全功能的两个信号（两个通道）可能
如果电缆损坏，应连接到外部电压。如果两个通道连接到外部
电压，安全功能不再工作。
ISO 13849-2描述了安全相关信号电缆的受保护电缆安装。用于
必须保护安全功能STO免受外部电压的影响。带有接地连接的屏蔽有助于
保持外部电压远离安全功能STO信号电缆。
接地回路可能会导致机器出现故障。仅在一端连接的屏蔽足以
接地，不会创建接地回路。
 安全功能STO的信号使用屏蔽电缆。
 请勿将电缆用于安全功能STO的信号或其他信号。
 连接屏蔽的一端。
警告
非预期设备操作
如果功率级的自动启用存在危险，则将参数IO\U AutoEnable设置为“off”
在应用程序中。
不遵守这些说明可能导致死亡、重伤或设备损坏。
警告
不可操作的安全功能
确保导电物质（水、污染或浸渍的油、金属屑等）
无法进入驱动器。
不遵守这些说明可能导致死亡、重伤或设备损坏。

To help avoid unintended restart of the motor after restoration of power (for example, after power outage), the parameter IO_AutoEnable must be set to "off". Also verify that a master controller will not trigger an unintended restart. Degree of Protection when the Safety Function is Used You must ensure that conductive substances cannot get into the product (pollution degree 2). Conductive substances may cause the safety function to become inoperative. Protected Cable Installation If short circuits and other wiring errors such as a cross fault between the signals of the safety function STO can be expected in connection with safety-related signals, and if these short circuits and cross faults are not detected by upstream devices, protected cable installation as per ISO 13849-2 is required. In the case of an unprotected cable installation, the two signals (both channels) of a safety function may be connected to external voltage if a cable is damaged. If the two channels are connected to external voltage, the safety function is no longer operative. ISO 13849-2 describes protected cable installation for cables for safety-related signals. The cables for the safety function STO must be protected against external voltage. A shield with ground connection helps to keep external voltage away from the cables for the signals of the safety function STO. Ground loops can cause problems in machines. A shield connected at one end only is sufficient for grounding and does not create a ground loop.  Use shielded cables for the signals of the safety function STO.  Do not use the cable for the signals of the safety function STO for other signals.  Connect one end of the shield. WARNING UNINTENDED EQUIPMENT OPERATION Set parameter IO_AutoEnable to "off" if the automatic enabling of the power stage presents hazards in your application. Failure to follow these instructions can result in death, serious injury, or equipment damage. WARNING INOPERABLE SAFETY FUNCTION Ensure that conductive substances (water, contaminated or impregnated oils, metal shavings, etc.) cannot get into the drive. Failure to follow these instructions can result in death, serious injury, or equipment damage.
