图3-20 RS485-(TDS-PA01)-现场总线通信的接线
如果多个驱动器通过RS485连接到网络中,则对通信系统的干扰会增加,因此
接线特别重要,您可以按照下图连接电缆:
图3-21 PLC与驱动器之间的通信(驱动器和电机接地良好)
如果通信仍然异常,则可以采取以下措施:
① 向PLC(或主机PC)提供单独的交流电源,并隔离交流电源;
② 如果使用RS485/RS232转换模块,则该模块应由单独的电源供电;
③ 将磁芯安装到通信电缆上,如果现场条件允许,降低载波频率。

Fig. 3-20 Wire connections of RS485-(TDS-PA01)-PROFIBUS communication
If several drives are connected in the network via RS485, the disturbance to the communication system increases, so
the wiring is especially important, you can connect the cables according to the figure below:
Fig. 3-21 Communication between PLC and the drive (the drive and motor are grounded well)
If the communication is still abnormal, then the following actions can be taken:
① Feed a separate AC supply to the PLC(or host PC) and isolate the AC supply;
② If RS485/RS232 conversion module is used, then the module should be powered by a separate power supply;
③ Mount magnetic core to the communication cable, reduce the carrier frequency if the field conditions permit.
