Encoder & position alarms: 31 alarm codes

The feedback path: encoder body, encoder cable, battery, measuring board and the stored position memory motor-side encoder -> encoder cable -> drive / measuring board acquisition -> position count and zero data -> battery-held memory

Inspection line: measure battery voltage and cable continuity first, then watch the feedback for jumps

Spares we carry: we carry feedback-path parts: encoder cables, battery packs, connector pins and the measuring-board type data for the brand

Most frequent causes (by pages seen)

• Loose or oxidized encoder connectors (seen on 3 pages)
• Encoder connector loose inside the joint (seen on 2 pages)
• Long storage without power (seen on 2 pages)
• Battery connector loose or corroded (seen on 2 pages)
• Cable fatigue from repeated torsion (seen on 1 pages)
• Encoder cable broken in the cable chain (seen on 1 pages)
