Theese berger lahr drives are known for having faults because of the old caps. So I already have new ones at hand. Tantals for example will be changed to multilayer ceramics, but that is another story.

Yes, suprisingly theese machines were sold as engraving machines. Really beefy engraving lol.

But of cause I will install a spindle with more power. Nothing fancy for this project. Just a er25 4kW spindle and an old vacoon vfd laying around.

The PDO entries of the EtherCAT master are 128 in number. Any error will occur if the number exceeds this limit. For the same type of enumerated points, you can use the abbreviated form for writing. For example：<pdoEntry idx="6000" subIdx="01" bitLen="32" halPin="bit-in" halType="bit"/> Here, an input point with a sub-index ranging from 1 to 32 is declared.

Dear friends, hello everyone. Regarding this issue, due to the busy work, it has been a week since then. Currently, we have basically understood the problem. I extracted two different Ethercat master station data from Wireshark and conducted a comparative analysis. From it, we can see that the entries of the PDO have a slight difference in the arrangement order. The main difference is reflected in the two special status words, namely " {0xf200, 0x01, 16}," and  {0xf100, 0x01, 16}. We are currently in contact with the manufacturer to confirm these two PDO entries. These two entries are used for a special design. Additionally, there is a problem with the parsing data of the data sent from IGH to PDO by the IO module!
