●电缆敷设时环境温度应不低于0℃。●电缆弯曲半径：三芯电缆不小于电缆外径15倍；单芯电缆不小于电缆外径20倍。电缆额定电压的选择●电缆的额定电压应适合于电缆系统的运行状况，用Uo/U（Um）KV表示。Uo--电缆设计用的导体对地或金属屏蔽之间的额定工频电压；U--电缆设计用的导体间的额定工频电压；Um--设备可承受的“最高系统电压”的最大值。
HYAP屏蔽通信电缆屏蔽通信电缆型号；高频电缆HYAPHYAPHYVPHYVPZRHYVP屏蔽通信电缆执行标准：YD/T屏蔽通信电缆结构特点：HYAP型市内通信电缆采用全色谱绝缘，铝塑综合护套(即电缆的纵包屏蔽铝带与护套粘结成一体，形成密封护层)，具有电气性能优越，施工方便的特点。
AD模块它的模拟量电压与数字量之间的关系如下图：在模块端10v模拟量对应4000数字量，按照此关系进行转换。在设备端位置传感器距离与模拟量电压信号之间的关系是：200mm量程对应10v模拟量输出，那里在PLC程序要得到准确的位置，位置与数字量之间的关系就是1mm=20数字量或者1数字量=0.05mm，加入我们检测了2000的数字量，经过换算就知道位置是100mm。至于开关量与模拟量之间的转换关系，应该说是模拟量怎么控制开关量，比如说电机转速超过某值就要关掉电机、温度大于多少度就要停止加热或小于多少要加热，这时候我们经过AD模块监控这些数据，在PLC中进行比较，根据比较结果来输出相应的开关动作。

严格来讲，编码器只会告诉你改如何定位，要如何执行，是需要靠数控系统（或者plc之类控制器）控制伺服或者步进电机来实现定位的，编码器好比人的眼睛，知道电机轴或者负载处于当前某个位置，工业上用的一般是光电类型编码器，下边简单说明一下。简单说下编码原理和位置测量光电编码器是在一个很薄很轻的圆盘子上，通过紧密仪器来腐蚀雕刻了很多条细小的缝，相当于把一个360度，细分成很多等分，比如成1024组，这样每组之间的角度差是360/1024度=0.3515625度。
Steel tape armoured mainly as the radial mechanical protection layer of the cable, and it also have additional total shielding effect, especially steel tape armoured and copper wire, copper tape screened, is adopted two different shielding materials, play a complementary role in electromagnetic wave shielding, shielding effect will be better.
