Project Description:Aikesiman Machinery Co., Ltd. is the largest, most professional non-woven fabric machinery manufacturers in southern China. After the application as Schneider inverter and servo motor control, inverter and servo using CANOPEN bus protocol, Aikesiman provide equipment, such as Guangdong and Xiamen, several textile mills project has appeared in the case of system instability, are in operation for some time the system will be off station or even does not work, reboot, and running for some time, and then appear the same fault, which greatly affected the normal operation of the factory.

Project Modification Plan：Schneider Guangdong, Shenzhen Schneider has sent all the relevant technical support engineers to find fault, tested and confirmed to affect the servo and inverter for the field bus communication interference, but the source of interference is not very clear, the failure probability is random. Schneider finally decided to use easy control of CANOPEN bus fiber optic repeaters and isolating repeaters to project upgrading project, the distance or easily disturbed sites using YFO series CANOPEN bus fiber optic repeaters, fully shielded bus interference ; for the short distance, the site less susceptible to interference using YHO3 series CANOPEN bus isolation repeaters, isolated bus segment, and filter out interfering signals. Try not to be under the premise wiring changes, adding communications relay module, project after upgrading, stability of the system, never appeared similar failure.
