TDE Automazione Servo Drive is a 3‑phase brushless servo controller designed for precise motion control, typically powered from 200–460 V AC with a 24 V DC control supply and capable of up to 7 A output. Common failure modes in this class include power‑stage overheating or burnout (especially if cooling is inadequate), loss of communication on Modbus/CANopen/Profibus/EtherCAT interfaces, and degradation of the sensor‑less control algorithm leading to oscillation or stalled motor conditions. Initial diagnostics should verify the AC input voltage and phase balance, confirm the 24 V DC rail integrity, inspect for visible signs of thermal damage or blown fuses on the power stage, and review any fault codes displayed on the drive’s HMI or communicated via its network protocols.[oss-gpt-20b]
