SMW System-55 ACCU-Smart Controller

The SMW System‑55 ACCU‑Smart is an industrial servo control and indexer controller used in CNC rotary tables and indexing units, featuring programmable steps and high repeatability. Common failure points for this class include power supply module degradation, I/O relay wear, and signal line insulation breakdown; the board often shows burn marks on the main driver ICs or capacitors. Begin troubleshooting by verifying 24 V DC input stability, inspecting all connectors for corrosion or loose pins, and checking the status LEDs for error codes before proceeding to a detailed PCB inspection.[oss-gpt-20b] Post Comment
