Overview
Siemens interface module 6ES7155-5BA00-0AB0 $r $n has been compared and tested, and it has been confirmed that the problem lies in the control board. After analysis, the problem may lie in the latch, as these signals are all controlled by this chip. After replacement, it was indeed repaired. In general, the inspection of faulty frequency converters should be carried out from the outside to the inside, from the outside to the inside, from static to dynamic, and from the main circuit to the control circuit. The following three checks are generally mandatory. Use a multimeter to test the diode characteristics and three-phase balance characteristics of the DC positive and negative terminals respectively.

This step can preliminarily determine the quality of the inverter module, and thus determine whether it can output without load. If there is a phase to phase short circuit or unbalanced state, it cannot be output without load. Open the cover and observe. If no problems are found in the above two steps, you can open the chassis, remove the dust, and carefully observe whether there is any damage inside the frequency converter, whether there are charred parts, whether the capacitor leaks, and so on.
Delete data blocks created by SFC from working memory; The remaining data blocks have preset values from the loaded memory. Reset the process image and all timer counters and bit memory, regardless of whether they have persistent allocation. The program in OB is executed once and then the loop program starts executing. During a hot start, restart the program execution at the program interrupt without resetting the timer counter and bit memory. At startup, all data flags, memory timers, process maps, and current values of data blocks are maintained, and the program in OB is executed once. Then the program is powered off from the breakpoint and CPUSTOP resumes execution.
After the execution of this' remaining loop ', the loop program begins to execute. Coldrestart initializes all data process maps, bit memory timers, and counters, including data blocks that are reset to their initial values stored in the loadmemory, regardless of whether the data is configured to be maintainable or non maintainable. Firstly, execute the startup organization block OB, which is not supported by all CPUs. The difference and connection between frequency converter and soft starter. Frequency converter and soft starter are actually two different products with different purposes. Frequency converters are mainly used in motor speed regulation. While they have the performance of soft starters and other starters, they also have significant advantages in starting characteristics compared to other starter devices.
