획득 & Replacement Guideline

5.1 Original Replacement Rules

Confirm complete model + exclusive factory ID to avoid parameter mismatch
Match 12-core shielded cable specification and length
Verify hollow shaft diameter (Φ10mm/Φ8mm), spring clamp type and stator coupling

5.2 Domestic Alternative Selection Criteria

Replacement Item	Must Match	Adjustable	Impact Level
Mechanical Dimension	Shaft diameter, mounting hole, housing size	—	Critical
Electrical Parameter	해결, signal type, supply voltage	Cable length (±1m)	Critical
Interface Definition	Pin assignment, shielding method	Connector type	중간
Precision Grade	Angular error, repeatability	Temperature drift	중간

5.3 Common Faults & 유지

Cable damage / shielding failure → Replace original cable assembly
Code disk oil contamination & dust accumulation → Professional cleaning (no scratching)
접촉불량 & signal attenuation → Re-terminate wiring and inspect connectors
Bearing noise & excessive backlash → Replace complete encoder unit
