Okamoto DX-4B-1 Servo Drive
 |
The Okamoto DX‑4B‑1 is a 400 W servo drive controller used to regulate motor torque and speed via PID algorithms and I/O interfaces. Common failures on this model include internal short circuits in the power stage (often reported by repair shops), degraded or failed MOSFETs, and blown protection fuses, leading to loss of output or erratic behavior. First‑check diagnostics: verify that the input supply voltage is within spec and that all fuses are intact; inspect the board for visible burn marks or solder bridges; and read any diagnostic error codes from the controller’s LCD or serial log to pinpoint a specific fault.[oss-gpt-20b] |
