Tajima MP131-2 Control Unit

The Tajima MP131‑2 is a servo‑drive controller board used in industrial embroidery machines and similar motion‑control applications. Common failure points for this class of units include power‑rail voltage drops, over‑current protection trips on the motor driver outputs, and firmware corruption or communication link loss with the host PLC. Begin troubleshooting by verifying that the 24 VDC supply is within spec and that all input/output connectors are clean and securely seated; check the board’s status LEDs or diagnostic display for error codes, then inspect the power‑regulation ICs and motor driver chips for burn marks or capacitors with bulging/bleeding. If the unit still fails to initialize, perform a firmware reload or reset using the manufacturer’s service tool.[oss-gpt-20b]
