Mazak 94101 WA Micro Disk System

The Mazak 94101 WA is a micro‑disk program transfer unit that interfaces with Mazak CNC machines via a 100 V AC supply and provides a numeric keypad, membrane switch, and display for operator interaction. Common failure modes in this class of equipment include power supply degradation (voltage drop or capacitor failure), drive motor/stepper coil wear, and firmware corruption on the micro‑disk media. Initial troubleshooting should verify that the unit receives proper 100 V AC input, check all connector pins for continuity and secure attachment, and review any error codes displayed on the HMI before proceeding to inspect internal capacitors and the disk read/write heads.[oss-gpt-20b]
