Teijin Seiki Co. AR15 drive

The Teijin Seiki AR15 is an AC servo drive used to control high‑precision industrial motors, typically integrated into machine tool or conveyor systems. Common failure modes for this class of drives include power supply over‑voltage, overheating of the IGBT/triac modules, and loss of communication with the host PLC due to faulty serial or Ethernet links. First‑check diagnostics: verify that the 200–230 V input is within spec and that the drive’s internal fuses are intact; inspect for visible signs of burnt components or thermal damage on the board; and review any displayed fault codes or status LEDs against the manufacturer’s troubleshooting guide.[oss-gpt-20b] Post Comment
