GE ISH100/30025/0/0/00/0/00/01/00 伺服电机必须正确使用变频器启用功能才能正常工作。然而，不能排除逆变器启用功能的意外丢失。逆变器启用功能的此类损失仅限于相关安全标准要求的上限。（见9.8安全标准）这用特性PFH和SFF来表示。从这些标准的意义上讲，可以满足停止类别0（安全扭矩关闭，STO）和停止类别（安全停止1，SS1）的要求。这两类都导致了无扭矩电机，而SS1在预定时间后进入这种状态。

GE ISH100/30025/0/0/00/0/00/01/00 伺服电机根据危险和风险分析结果，可能有必要选择一个额外的制动器作为安全选项（例如，用于未决负载）。该功能通过PS-5输入端的信号进行选择，该信号用于PS-5组的所有驱动器。电源电压（AC）无需中断。如果只有连接到PS-5的一些驱动器应处于安全状态，则可以通过配置驱动器来实现。这是有趣的，例如对于清洁模式。

GE ISH100/30025/0/0/00/0/00/01/00 伺服电机如果设置了可选模块iSH-DIS1，则IE信号将被忽略。要执行紧急停止，必须中断PS-5上的电源。由于逆变器启用功能的设计寿命为15年，因此无需进行例行检查即可维护或验证功能安全性。由于组件的老化和相关的故障率，在这15年之后，无法对逆变器启用功能做出任何声明。如果希望在这段时间后确保安全标准和产品责任方面的功能，需要更换iSH。

The GE ISH100/30025/0/0/00/0/00/01/00 servo motor must use the frequency converter activation function correctly to function properly. However, the accidental loss of the inverter activation function cannot be ruled out. The loss of inverter activation function is limited to the upper limit required by relevant safety standards. This is represented by the characteristics PFH and SFF (see 9.8 safety standards). In the sense of these standards, it can meet the requirements of stop category 0 (safety torque closure, STO) and stop category 1 (safety stop 1, SS1). Both of these types result in a torque free motor, and SS1 enters this state after a predetermined time.

The GE ISH100/30025/0/0/00/0/00/01/00 servo motor may need to select an additional brake as a safety option (e.g. for pending loads) based on the results of the hazard and risk analysis. This function is selected through the signal from the PS-5 input end, which is used for all drivers of the PS-5 group. The power supply voltage (AC) does not need to be interrupted. If only some drives connected to the PS-5 should be in a safe state, it can be achieved by configuring the drives. This is interesting, for example, for cleaning mode.

If the optional module iSH-DIS1 is set for the GE ISH100/30025/0/0/00/0/00/01/00 servo motor, the IE signal will be ignored. To perform an emergency stop, the power supply on the PS-5 must be interrupted. Due to the design lifespan of the inverter activation function being 15 years, there is no need for routine inspections to maintain or verify functional safety. Due to the aging of components and related failure rates, it is not possible to make any statements regarding the activation function of the inverter after these 15 years. If you want to ensure the functionality of safety standards and product responsibility after this period, you need to replace iSH.
