Mitsubishi MDS-B-SP-110 Amplifier Repair Service

Professional diagnostic and board-level repair service for this Mitsubishi MDS-B-SP-110 Amplifier.

MDS‑B‑SP‑110 is an 11 kW AC spindle drive/spindle amplifier designed for CNC applications, operating at 200–230 V AC and supporting both synchronous and asynchronous motors with air‑cooling. Common failure points in this class of drives include overheating due to dust accumulation on cooling fins, insulation degradation of power MOSFETs or IGBTs, and failure of the built‑in current sensor or encoder interface. First‑check diagnostics: verify input voltage and phase balance, inspect for visible signs of thermal damage or loose connections, and review any fault codes displayed on the drive’s panel or communicated via its PLC interface.
