Sanyo-Denki PDT-B3B-10 Servo Board
 |
The Sanyo Denki PDT‑B3B‑10 is a servo amplifier/drive board used in CNC and industrial motor control systems. Common failure points for this model include burned or degraded MOSFETs on the output stage, damaged gate drivers, and capacitor degradation leading to over‑voltage spikes; insulation breakdown between power and signal traces can also cause erratic behavior. First‑check diagnostics should verify that the board receives correct supply voltage (48 V DC nominal) and that all input signals from the controller are within spec; inspect for visible burn marks or swollen electrolytics, then test output transistors with a multimeter and confirm PWM waveform integrity on an oscilloscope.[oss-gpt-20b] |
