The overcurrent alarm in plywood production line servo repair is more common, content economic electromechanical failure in dealing with such 'OC' error can be said to be handy, plus plenty of accessories, server repair is very fast. The points: lightning plywood production line servo repair plant generally has lightning absorb networks, mainly to prevent the instant the lightning invasion, so that damage to the server. But in practical work, especially the power cord row hit introduced, absorb network server alone is not content with the requirements. In lightning active region, the subject is particularly important if the power supply is a row hit into the line, installed into the line the inverter dedicated arrester (optional), or according to specifications from the server 20m distant embed pipe do The dedicated ground protection. If the power cable entry, you should do a good job of the lightning protection system of the control room, prevent lightning fleeing the destruction device. The practice shows that this method is basically able to effectively solve the lightning topic. Plywood production line servo error failure ER08 maintenance analysis: server to thrown ER08 fault code indicates that the drive is in undervoltage fault state. Main reasons the input power is too low or the lack of phase, the the server internal voltage detection circuit is abnormal, abnormal server main loop circuit. The general-purpose servers voltage input range of three phase 320V ~~ 460V. When the server is in the practical application of full load operation, may float to the surface and the input voltage drops below 340V undervoltage protection, then progress to the mains input voltage or server derating;, if the input voltage is normal, the server running but thrown the ER08 fault, and you can judge for server internal failure. Plywood production line servo repair encountered in day-to-day maintenance will not only overcurrent error will encounter other types of failure, if not solve the problem, you can contact Yung economic mechanical and electrical engineers for technical assistance.
