Flame-retardant cable: the electric wire and cable are produced by external heating. In order to achieve the purpose of flame retardant, the three elements must be caused, namely, combustible gas, heat and oxygen. Therefore, generally USES is added in the sheath material containing halogen halide and metal oxide, from the perspective of flame retardant, that's very good, but, because of the halide is contained in these materials, in a lot of smoke and released when halogenated body, so, the low visibility when fire, bring a lot of personnel evacuation and fire obstruction, whereas people more for functioning suffocated to death.

在阻燃型系列产品中，成功地应用了隔氧技术，不仅0.6/1KV的聚氯乙烯绝缘和交联聚乙烯绝缘阻燃电力电缆能达到GB/T12666.5《成束电力电缆燃烧试验方法》中A类，而且额定电压6/10KV及8.7/15KV交联聚乙烯阻燃电力电缆也能达到A类高阻燃要求且有较大裕度。
下面介绍速度-动态转矩（ue）特性的测量法。步进电机的动态转矩有最大失步转矩与起动转矩。这两种转矩随驱动频率的增加而下降，原因是由于线圈的电抗增加，电流减少造成的。在低速运行时，其运行在振动带区域，转矩会突然下降，此为转子的自然振动频率与驱动频率共振产生的现象；或者，在转子转动方向突然发生改变瞬间，同时接收到驱动指令脉冲，也会产生此现象。这些现象均需要正确测量电磁转矩。本节介绍3种测量转矩的方法及其测量原理。
This product is suitable for electronic computers with rated voltage of 500V and cables with high re of anti-interference. Type K B low density polyethylene with anti-oxidation property is adopted for insulation of cable core. Polyethylene high insulation resistance, good resistance to voltage, small dielectric coefficient and temperature and the influence of variable frequency dielectric loss is small, can not only meet the res of transmission performance, and can ensure the service life of the cable. In order to reduce crosstalk and external interference between circuits, the cable adopts shielding structure. The shielding res of cables are respectively adopted according to different situations, such as the method of shielding the hinged combination, the method of shielding the hinged combination, and the method of shielding the hinged combination after the hinged combination. Shielding materials are round copper wire, copper belt, aluminum belt/plastic composite belt three. Shielding pair and shielding pair have good insulation performance. If there is potential difference between shielding pair and shielding pair, the signal transmission will not be affected.

1.1FC105功能描述SCALE（FC105）功能将一个整形数INTEGER（IN）转换成上限、下限之间的实际的工程值(LO_LIMandHI_LIM)，结果写到OUT。公式如下：OUT=[((FLOAT(IN)–K1)/(K2–K1))*(HI_LIM–LO_LIM)]+LO_LIM常数K1和K2的值取决于输入值（IN）是双极性BIPOLAR还是单极性UNIPOLAR。双极性BIPOLAR：即输入的整形数为–27648到27648，此时K1=–27648.0，K2=+27648.0单极性UNIPOLAR：即输入的整形数为0到27648，此时K1=0.0，K2=+27648.0如果输入的整形数大于K2，输出(OUT)限位到HI_LIM,并返回错误代码。
