Why can't I see it directly as % on the PLC side? Attachment Ekran görüntüsü 2025-03-11 155355.jpg (170 Downloads)

This is defined in the Profidrive standard. The scaling of the current is calculated with p2002. On plc side 16384 must be scaled with the same value from p2002. A detailed description is available in the operating instructions of the DCM under chapter 10.3.
