Polatech SMD 026 976 linear encoder

Polatech SMD 026‑976 is a linear position encoder used in Polar/EB and 115EMC cutting machines to provide precise axis feedback. Common failure modes include broken or missing cables, pinout mismatches, and signal line shorts that cause misread positions or loss of communication with the drive controller. First‑check steps: verify power and ground continuity on the encoder cable, test input/output voltage levels against spec, inspect for visible insulation damage or solder joint failures, and review any error codes logged by the machine’s control system.[oss-gpt-20b]
