详细介绍

CTB810,HN800 通信终端板连接到MB810左侧

用于长度超过3 m的数字信号和所有模拟信号的屏蔽电缆。如果两个接地点属于同一接地线，则通过金属夹或类似方法直接在干净的金属表面上连接两端的每个屏幕。否则，将电容器的一端接地。在转换器柜中，这种连接必须直接在靠近端子的金属板上进行，如果电缆来自外部，也必须在PE杆上进行。在电缆的另- -端将屏幕与信号发射器或接收器的外壳很好地连接起来。使电机电缆远离其他电缆线路。多个驱动器的电机电缆可以并联安装，彼此相邻安装。电机电缆、输入电源线和控制电缆应安装在单独的托盘上避免电机电缆与其他电缆长时间并联，以减少驱动器输出电压快速变化引起的电磁干扰。如果控制电缆必须穿过电源线，请确保它们以尽可能接近90度的角度排列。请勿将备用电缆穿过驱动器或机柜。电缆桥架之间以及与接地电极之间必须具有良好的电连接。铝托盘系统可用于改善局部电位均衡。

Shielded cables for digital signals and all analog signals exceeding 3 meters in length. If two grounding points belong to the same grounding wire, connect each screen at both ends directly on a clean metal surface using a metal clip or similar method. Otherwise, ground one end of the capacitor. In the converter cabinet, this connection must be made directly on the metal plate near the terminal, and if the cable comes from outside, it must also be made on the PE pole. Connect the screen to the housing of the signal transmitter or receiver at the other end of the cable. Keep the motor cables away from other cable routes. The motor cables of multiple drives can be installed in parallel, adjacent to each other. Motor cables, input power lines, and control cables should be installed on separate trays to avoid prolonged parallel connection between motor cables and other cables, in order to reduce electromagnetic interference caused by rapid changes in driver output voltage. If the control cables must pass through the power cord, make sure they are arranged at an angle as close to 90 degrees as possible. Do not thread spare cables through drives or cabinets. There must be good electrical connection between cable trays and the grounding electrode. The aluminum tray system can be used to improve local potential balance.
