The Diversen WL‑00215 is a Panasonic AC servo driver designed to control industrial AC servo motors from 200–220 VAC. Common failures on this class of drivers include over‑temperature shutdowns due to inadequate cooling, phase or voltage sensor faults, and failure of the integrated power MOSFET array; these can manifest as error codes such as “E01” (over‑current) or “E02” (phase loss). Begin troubleshooting by verifying the input supply voltage and waveform, inspecting for burnt components or loose connections on the driver board, and checking the motor phase wiring and encoder signals. If an error code is present, cross‑reference it with Panasonic’s technical reference to identify the specific fault condition.[oss-gpt-20b]
