Head to head
ABB IRB 4600 vs Yaskawa Motoman GP50
A specification duel across payload, reach, precision, and footprint, with a plain read on which arm suits which job.
High-speed arm for handling and palletizing support
Versatile 50 kg robot for handling and packaging
Specification duel
Green marks the stronger figure. Unconfirmed specs are shown but not scored.
The verdict
The specs separate them here: the ABB IRB 4600 carries more, 60 kg to the Yaskawa Motoman GP50's 50 kg. If precision drives the job, the Yaskawa Motoman GP50 holds the tighter repeatability at ±0.03 mm. They run different controllers, the ABB IRB 4600 on the OmniCore and the Yaskawa Motoman GP50 on the YRC1000, so whichever platform your team already programs and stocks parts for is a real tiebreaker. Mounting options differ: the ABB IRB 4600 lists Floor, Tilted, and Inverted, and the Yaskawa Motoman GP50 lists Floor, Ceiling, Wall, and Tilt. Both are aimed at material handling and machine tending, with the ABB IRB 4600 stretching to arc welding and the Yaskawa Motoman GP50 to packaging.
Choose this one when
Job fit first, then the controller and cell constraints that decide which arm you can actually install.
Choose the ABB IRB 4600 when
- Fast cycle times for a 60 kg class arm
- Wide reach for pallet and large-part work
- Slim lower arm for tight cell integration
- Broad EOAT and vision ecosystem support
Watch for
- Higher power draw than smaller ABB arms
- Large swept volume needs generous cell space
Choose the Yaskawa Motoman GP50 when
- Good payload to reach balance
- Fast cycle times for its class
- Reliable in continuous packaging lines
- Ceiling mount option available
Watch for
- Not intended for the heaviest palletizing loads
- Larger footprint than compact GP models
Controller ecosystem
Programming habits, spare parts, and pendant familiarity often decide the pick when payloads are close.
- Brand
- ABB
- Controller
- OmniCore
- Class
- 6-axis industrial
Service, spares, and pendant training for the ABB IRB 4600 run through ABB's OmniCore stack.
- Brand
- Yaskawa
- Controller
- YRC1000
- Class
- 6-axis industrial
Service, spares, and pendant training for the Yaskawa Motoman GP50 run through Yaskawa's YRC1000 stack.
These arms run different controllers (OmniCore vs YRC1000). If your team already programs one of them, retraining programmers and stocking a second set of spares usually costs more than a small payload or reach advantage on paper.
Mounting, footprint, and mass
How the arm can be oriented in the cell, and how much mass you have to mount.
| Field | ABB IRB 4600 | Yaskawa Motoman GP50 |
|---|---|---|
| Mounting | Floor, Tilted, and Inverted | Floor, Ceiling, Wall, and Tilt |
| Robot mass | 445 kg | 570 kg |
| Protection (IP) | IP67 | IP67 wrist / IP54 body |
Heavier arms want stiffer bases and more clearance around the swept volume, and they push freight and rigging costs up on the install. IP ratings only cover the section they name, so a wrist-only rating protects the wrist and nothing else; check the body rating separately before you commit the arm to a washdown or dusty cell.
Application fit

Speed and cycle-time planning
Speed is rarely a single datasheet number across brands. Use payload, reach, and class as the planning frame, then confirm cycle time in a path study.
The ABB IRB 4600 is a 6-axis industrial arm rated 60 kg at 2050 mm with ±0.06 mm repeatability. The Yaskawa Motoman GP50 is a 6-axis industrial arm rated 50 kg at 2061 mm with ±0.03 mm. Class changes how speed shows up in a cell: collaborative arms slow down near people and can speed up in a guarded mode, while industrial arms run at rated speed inside a fence or scanner field. Which arm cycles faster on your part depends on the path, the payload, and the safeguarding, so confirm the takt with a path study before you quote it.
Common questions
- Which has more payload, the ABB IRB 4600 or the Yaskawa Motoman GP50?
