Quality Measurement Systems Q‑500 is a 2–3‑axis electro‑optical digital readout (DRO) used on CNC mills and lathes to provide real‑time axis position feedback. Common failure modes include mis‑alignment or contamination of the optical sensor head, damaged or frayed wiring between the reader and the machine controller, power‑supply voltage drops, and loss of calibration data after a reset or firmware update. First‑check diagnostics: verify 24 V DC supply to the DRO module; inspect the sensor head for dust, debris, or physical damage and clean with isopropyl alcohol; confirm all wiring connections are secure and free from corrosion; review any error codes on the machine controller that reference the DRO or readout.[oss-gpt-20b] |
