Fuji Electric FRE-100 Ac Servo Amp

FRE‑100 is a Fuji Electric AC servo drive used for high‑speed motor control in industrial automation. Common failure points for this class of drives include power supply over‑voltage, capacitor degradation on the DC bus, overheating of the MOSFET array, and loss of communication with the host controller due to corrupted firmware or damaged I/O modules. Initial checks should verify that the input voltage is within spec, confirm proper grounding and isolation, inspect for visible signs of component damage (burn marks, swollen capacitors), and review any error codes displayed on the drive’s panel or via its diagnostic port.[oss-gpt-20b]
