Overview
The PWM voltage transmitted on the output cable of the Siemens analog module 6ES7531-7PF00-0AB0 $r $n frequency converter also contains rich high-frequency components, which can generate electromagnetic wave radiation and form radiation interference. The characteristic of radiation interference is that when other electronic devices approach the frequency converter, the interference phenomenon becomes severe. How to solve the interference problem. The interference processing method for frequency converters suppresses the harmonics generated by frequency converters. Optional filtering products include frequency converter input filters, frequency converter output filters, frequency converter input reactors, frequency converter output reactors, etc.

Inserting a reactor in series into the input circuit is an effective method to suppress lower harmonic currents. In addition, to prevent the frequency converter from interfering with signals and control circuits, separate isolated power supplies need to be used to power the controller instruments and industrial computers.
During debugging, various possible situations should be fully considered, and each branch and possible progress path in the system's different working modes and selective sequence function table diagram should be checked one by one without omission. After discovering the problem, the ladder diagram and the program in the PLC should be modified in a timely manner until the relationship between the input and output quantities meets the requirements in various possible situations.
If the set values of some timers or counters in the program are too large, in order to shorten debugging time, they can be reduced during debugging, and their actual set values can be written after simulating debugging. While designing and simulating debugging programs, it is also possible to design and manufacture control consoles or cabinets, and install and wire other hardware besides PLCs simultaneously.
With the advancement of technology, the development of intelligent chips has gradually matured, and the intelligence level of equipment has correspondingly increased. As a result, the automation control system composed of open standard fieldbus technology between intelligent devices has also gradually matured. So Siemens PLC not only uses industrial Ethernet and Profibus.
The common terminal of the contact is in the same direction as the incoming end of the coil, and the outgoing end is divided into normally open and normally closed. The method to determine normally open and normally closed is to insert the relay into the relay socket and measure the on/off status of the common terminal to the two output terminals with the on/off range of the multimeter. The one that is on is normally closed, and the one that is not is normally open. If you don't have a multimeter, I have a little experience to tell you. Generally, the contacts of the intermediate relay are open and closed, that is, the top row is the normally open point and the bottom row is the normally closed point. In general, when the auxiliary contacts provided by the contactor are insufficient or the control voltage does not match the voltage of the contactor coil, we can use an intermediate relay as a transfer point to complete the connection of the entire circuit.
