介绍 +Q957 防止误启动选件，并说明如何布线、启动、测试、验证、使用和维护。
防止误启动 (POUS) 功能用于禁用变频器（逆变器）输出功率半导体的控制电压。这样可防止变频器生成电机旋转所需的力矩。POUS 功能会激活变频器的传动互锁 (DIL) 功能。
通过使用此功能，可以在不关闭和断开变频器的情况下，对机器的非电气部件执行短时间操作（如清洁）和/ 或和维护工作。
用户可使用控制台上安装的开关激活防止误启动功能。打开开关后（处于关闭位置），将激活 POUS 功能，且 POUS 指示灯亮起。

Emerson 1C31224G01 controller determines whether the program jumps according to whether the jump condition is met. When the instructions involved in the input, output state, DCS read from the input image register and component image register, according to the user program, the operation results are stored in the component image register. In the case of component image registers, the contents vary as the program executes.
