The Delem DA‑66W is a press‑brake controller that runs an embedded real‑time Windows OS and offers 2‑D graphical programming with automatic bend calculation and collision detection. Common failure points for this model include the power‑input board (overvoltage or thermal overload), the main logic PCB (shorts in the I/O lines or damaged capacitors), and the motor‑driver interface (faulty current sensors or encoder signals). Initial checks should verify that the unit receives correct 24 V DC, inspect the control board for burnt components or loose connectors, and review any logged error codes on the display to pinpoint whether the issue is electrical, mechanical, or software.[oss-gpt-20b]
