Acroloop Motion Control Systems — 00:D0:5B (MA-L)

Acroloop Motion Control Systems, Inc. holds a single IEEE MA-L block, 00:D0:5B, registered to "ACROLOOP MOTION CONTROL" out of Chaska, Minnesota. The registry name reads short because the raw the IEEE MA-L registry row splits mid-name — the organization line carries "ACROLOOP MOTION CONTROL" while the trailing "SYSTEMS CHASKA MN US 55318" lands in the address field, a common IEEE CSV formatting quirk rather than two separate facts; the full corporate name is Acroloop Motion Control Systems. Behind this lone prefix sits a real, well-documented industrial manufacturer, not a bare single-OUI shell. Acroloop built the ACR series of multi-axis motion controllers — the ACR1500, ACR2000, ACR8000/8010/8020, ACR8100/8200 lineage — plus OEM software such as AcroMill NT and the AcroLIB programming API, used in CNC and industrial-automation machinery. The company was acquired by Parker Hannifin Corporation in 2001 and folded into Parker's Compumotor Division; the product line continued under the "Parker Acroloop" brand and later evolved into Parker's ACR9000-series controllers. Legacy manuals and catalogs remain hosted on parkermotion.com and divapps.parker.com, and specific model numbers still surface on independent industrial-surplus and repair-vendor listings. Because these are embedded/industrial controller products rather than consumer IT gear, the 00:D0:5B OUI would appear on networked motion-control hardware rather than general networking equipment. IEEE publishes no assignment date for OUI blocks, so no registration date is recorded here.

IEEE assignment

00:D0:5B → "ACROLOOP MOTION CONTROL", Chaska, MN, US [Confirmed] — IEEE MA-L (raw row MA-L,00D05B,ACROLOOP MOTION CONTROL,SYSTEMS CHASKA MN US 55318)

Registry / block size

MA-L (24-bit OUI); single prefix (00:D0:5B) only [Confirmed] — the IEEE MA-L registry. No match in the IEEE MA-M registry (MA-M) or the IEEE MA-S registry (MA-S).

Registered company name

Acroloop Motion Control Systems (registry field truncates to "ACROLOOP MOTION CONTROL"; "SYSTEMS" carried into the address line by an IEEE CSV column-split artifact) [Confirmed] — the IEEE MA-L registry, https://controlrepair.com/product/manufacturer/acroloop-motion-control-systems-1808

HQ / country

Chaska, MN 55318, US (registry address) [Confirmed] — the IEEE MA-L registry. One independent web source additionally gives a street address of 3650 Chestnut Street North, Chaska, MN 55318 [Likely] — https://controlrepair.com/product/manufacturer/acroloop-motion-control-systems-1808

Company status

Registration date

Unknown — IEEE publishes NO assignment/registration date for OUI blocks (the IEEE MA-L registry columns are only Registry, Assignment, Organization Name, Organization Address). Any "date registered" on third-party MAC-lookup tools is a database artifact, not an IEEE fact. (A "Oct 7, 2002" date on the AcroLIB manual is a document-effective date, unrelated to OUI registration, and is not used here.)

[Confirmed] — the IEEE MA-L registry

IANA reference

N/A — not applicable to OUI/MAC vendor registry data; leave blank [Confirmed]

Security / abuse context

Unknown / no findings — no CVEs, advisories, or threat-intel reports surfaced for this OUI or the ACR-series controllers. Expected null for legacy industrial motion hardware; sourced absence, not a confirmed clean bill of health. [Unknown]

Analyst note

single-OUI vendor, but backed by a genuine, checkable device catalog and post-acquisition corporate lineage — the opposite of a bare unverifiable registration.
