Serial numbers

Understanding Universal Robots serial numbers

General SN:

UR20 / UR30 SN:

OEM vs. Standard Robots:

(Only applicable for e-series)

How to differentiate standard robots from OEMs is from the SN structure:
SN structure: YYYY (year) G (generation) S (size) XXXXX (production number).

The number from the OEM starts with:

90000 if DC OEM
- Eg.: 20215590001
80000 if AC OEM
- Eg.: 20215580001

E-Series

	Made from	Made to	Serial no. from	Serial no. to
UR3e	2018	Still in production	20185300000	Still in production
UR5e	2018	Still in production	20185500000	Still in production
UR10e	2018	Still in production	20185000000	Still in production
UR16e	2019	Still in production	20195600000	Still in production

The control boxes have changed for both CB3.1 and e-Series in June 2019: https://www.universal-robots.com/articles/ur/documentation/product-alert-control-box-updates-june-2019/

UR10e 12,5Kg vs. 10Kg:

The UR10e - 12,5Kg has a different number than the old UR10e - 10Kg:

UR10e 10Kg: YYYY (year) 5 (e-Series Generation) 0 (10Kg) 00000 (Production Number)
- Eg.: 20215000001
UR10e 12,5Kg: YYYY (year) 5 (e-Series Generation) 2 (12,5Kg) 00000 (Production Number)
- Eg.: 20215200001

cb3.1

	Made from	Made to	Serial no. from	Serial no. to
UR3	2015	Still in production	2015330001	Still in production
UR5	2016	Still in production	2016351864	Still in production
UR10	2016	Still in production	2016301779	Still in production

UR3

The CB3.1 controller is a bit different from the CB3.0 controller due to the following
- It runs of a USB version with more process power
- It runs of a USB key (USB 3.0) where all former CB-versions runs of a flashcard

The control boxes have changed for both CB3.1 and e-Series in June 2019: https://www.universal-robots.com/articles/ur/documentation/product-alert-control-box-updates-june-2019/

cb3

	Made from	Made to	Serial no. from	Serial no. to
UR5	2014	Still in production	2014350001	2016351863
UR10	2014	Still in production	2014300001	2016301778

CB2 and CB3 looks the same on the outside. However, on the inside there are many differences. Here is a quick overview of the differences.

True absolute magnetic encoders
- Old type UR uses incremental optical encoders
- Each mark on encoder disk is unique, making it unnecessary for battery backup
- This results in no referencing needed at power up and other advantages
Safety Control Board (CB3) replaces Masterboard(CB2)
Additional I/O, Total is now 16 inputs and 16 outputs in control box
- 8 inputs and 8 outputs are easy configurable as Safety signals or general-purpose signals
- Connectors replaces screw terminals
- Connectors are hardcoded, avoids incorrect insertion
UR Safety 3.0, Patented adjustable Safety System
- UR Safety 3.0 is certified by TÜV
- All safety functions are safety rated to Performance Level d (PLd)
            Tested in accordance with:
              EN ISO 13849:2008 PLd
              EN ISO 10218-1:2011, Clause 5.4.3
Software improvements
- Program execution will continue from where it stopped (result of the true absolute encoder)
- Realtime performance, part of software re-written
- Conveyor tracking, decoding of encoders now runs at 40kHz (CB2: 125Hz)
- Singularity, speed is reduced around singularities, so the robot is able to move through singularities

The “end of Support” for CB2 is scheduled for the 30/06/2022: https://www.universal-robots.com/articles/ur/documentation/product-alert-end-of-support-cb2/

Note: The controller on a CB1 can be updated to a CB2. Ask Global. Prod. Supp. about price and how
