The Yaskawa CACR‑SR05BE12G‑E is a 0.5 kW AC servo drive from the Servopack series, designed for CNC and robotic applications with a 200–240 V input range and 50/60 Hz operation. Common failure points in this class include overheating of the power MOSFET array, insulation breakdown on the motor winding connections, and encoder signal loss or drift; these can manifest as over‑temperature alarms, erratic speed control, or loss of position feedback. First‑check diagnostics should verify that the supply voltage is within spec and stable, inspect all I/O connectors for corrosion or loose contacts, and review any fault codes in the drive’s diagnostic display for indications of motor overload or encoder errors.[oss-gpt-20b]
