The TDE DSC‑06N/B0 is a 4.1 A, 240 V industrial servo drive used for speed/position control in CNC and packaging equipment. Common failure points include power‑stage MOSFET or IGBT burnout, capacitor degradation on the DC bus, overheating of the cooling fan, and loss of communication with the host controller (e.g., lost Modbus/TCP link). Typical symptoms are a red status LED, audible “hissing” from the heat sink, or repeated error codes such as “E01 – Over‑temperature” or “E02 – Communication fail.” First‑check diagnostics: verify 240 V AC input and proper grounding; inspect the drive’s internal fan and thermal pads for dust or oil buildup; check the DC bus voltage and capacitor ESR; and review the drive’s error log via its serial or Ethernet interface.[oss-gpt-20b]
