指令值模块以24 V直流电压运行，电源单元［7］提供内部所需正、负电压。电源单元开始工作后，绿色“power”LED点亮。通过使能输入端口3的信号，可接通或关闭操纵信号。无使能信号时，操纵信号相对于指令值参考地GND为0%。

求和环节 [2] 将通过“Z”电位器调节的偏置量叠加到外部给定的指令值上，从而补偿控制侧的零点偏差，并精确调整液压零点。利用可调特性曲线发生器 [3]，可分别设置正、负信号的阶跃量和最大值，使其独立匹配液压系统要求。

电位器“S+”“S–”用于补偿阀的遮盖区，“G+”“G–”用于设定比例伺服阀的最大流量，参见图示、特性曲线及调试说明。

操纵信号与指令值采用同一参考电位。参考电位发生波动时，加法器［4］对操纵信号进行相应修正。
