Sony Magnescale LA10‑35RH0 DRO is a magnetic scale digital readout used on CNC lathes and milling centers to provide high‑resolution axis position feedback. Common failures include loss of signal or drift due to coil degradation, misaligned or damaged magnetic tape, power supply instability, or connector corrosion; the unit may also exhibit intermittent “no data” displays if the internal microcontroller resets. Initial diagnostics should verify 24 V DC input and continuity across the drive‑to‑readout cables, inspect the magnetic tape for scratches or contamination, and check the DRO’s serial port or display panel for error codes or flashing indicators before proceeding to component replacement.[oss-gpt-20b]
