Control Techniques SAE 1100 SNP CRA 001 is an AC spindle drive used in CNC milling and drilling machines, typically powered at 380/460 V with a variable‑frequency motor controller. Common failures on this class of drives include power supply over‑voltage or under‑voltage causing the VFD to trip, capacitor degradation leading to phase imbalance, and encoder/feedback loss due to wiring corrosion or connector wear. First‑check steps: verify input voltage and filter capacitor condition; inspect all I/O connectors for loose or corroded pins; review any fault codes displayed on the drive’s panel or via its diagnostic port.[oss-gpt-20b] |
