Esa NSK ESA-Y3008T25-21.1 Drive

ESA‑Y3008T25‑21.1 is an NSK Megatorque servo motor driver rated for 180–242 V AC and 1.5 A output, commonly used in CNC spindle or linear motion systems. Typical failure modes include power supply degradation (over‑voltage/under‑current), overheating of the MOSFET array, firmware mismatches leading to error codes, and insulation breakdown between drive pins and motor leads. First‑check diagnostics: verify input voltage and current against spec; inspect for burn marks or swollen capacitors on the PCB; review any displayed fault codes via the serial port or diagnostic LED; and confirm that the motor’s feedback encoder is correctly connected and functioning.[oss-gpt-20b] Post Comment
