Product Description
Delta Tau ACC‑70E (Part No.603962‑102) is a MACRO fiber‑optic ring communication expansion board for UMAC / Turbo PMAC motion control system, 3U UBUS rack plug‑in card. It establishes high‑speed real‑time fiber communication between main controller and remote MACRO servo drive nodes for distributed multi‑axis motion control network. Fiber‑optic transmission provides excellent immunity against industrial electromagnetic interference. It supports MACRO ring topology for servo‑axis expansion. Compatible with UMAC and Turbo UMAC rack systems.
