FANUC M-900iB/400L industrial robot with R-50iA controller
FANUC M-900iB/400L with R-50iA controller is a extended-reach heavy-payload 6-axis industrial robot from the M-900 family. It has a rated wrist payload of 400 kg and a maximum working reach of 3704 mm.
Variant name / also known as: FANUC M-910/400F-37B.
The M-900 family is part of FANUC's range of very-high-payload industrial robots. It is intended for heavy component handling, large fixtures, automotive production and press applications. The mechanical configuration of this model is identified as Extended reach, allowing the robot to be selected for a clearly defined combination of payload, reach and installation layout.
This model uses 6 controlled axes and has a published positioning repeatability of ±0.10 mm. Its stated mounting arrangement is floor. Final payload capacity must be checked against the complete tool, workpiece, center-of-gravity and inertia data rather than the nominal wrist payload alone.
Controller compatibility: the model is listed for the R-50iA control generation. For CMS classification, all supported cabinet forms are consolidated under the single controller name R-50iA. Electrical supply, cabinet size, safety options, fieldbus interfaces, software packages and regional availability still have to be confirmed for the exact robot order code.
Typical applications
- advanced manufacturing
- handling of parts
- loading and unloading of parts
- press tending
For a Eurobots project, FANUC M-900iB/400L can be evaluated for new automation, controller-standardization studies, replacement projects, process trials and complete robotic cells. Engineering approval should be based on the exact mechanical-unit specification, load diagram, mounting orientation, environmental option and controller software release.
Alias note: the variant name FANUC M-910/400F-37B has been retained to help identify the exact FANUC order-code style model.
