# FANUC M-950/500F-28A

Hardware · `M-950/500F-28A` · verification: source checked

The M-950/500F-28A is a six-axis serial-link industrial robot with a 500 kg maximum load capacity at the wrist and a 2830 mm reach. It is built for lifting and moving large, heavy objects. Because it uses a serial-link mechanism rather than a parallel link, the arm can extend upright and rotate backward with reduced interference, which suits tight installation layouts.

## Study notes

- Serial-link mechanism, not a parallel-link design; the arm can extend upright and rotate backward with minimal interference.
- Repeatability of ±0.08 mm is stated as based on ISO 9283.
- Mechanical weight of 2500 kg is given without the controller.
- Motion ranges: J1 370°, J2 150°, J3 392°, J4 720°, J5 244°, J6 720°.
- Maximum moments/inertia: J4 3420 N·m / 1100 kg·m², J5 3420 N·m / 1100 kg·m², J6 1850 N·m / 445 kg·m².
- Average power consumption is 5 kW.
- Body protection is IP54; wrist and J3 arm protection is IP67.
- Maximum axis speeds may not be reached during short-distance motions.
- Runs on the R-50iA controller series, offered with three cabinet options.
- Compatible with the FANUC tablet teach pendant.
