Which has more payload, the ABB IRB 390 FlexPacker or the FANUC DR-3iB?

The ABB IRB 390 FlexPacker has more payload at 15 kg versus 8 kg.

Which reaches farther?

The FANUC DR-3iB has more reach at 1600 mm versus 1300 mm.

Which is more precise?

The ABB IRB 390 FlexPacker holds tighter repeatability at ±0.02 mm.

Should I choose the ABB IRB 390 FlexPacker or the FANUC DR-3iB?

Match the pick to the job. The ABB IRB 390 FlexPacker is a delta arm at 15 kg and 1300 mm. The FANUC DR-3iB is a delta arm at 8 kg and 1600 mm.

Do the ABB IRB 390 FlexPacker and FANUC DR-3iB use the same controller?

No. The ABB IRB 390 FlexPacker uses IRC5 / OmniCore and the FANUC DR-3iB uses R-30iB Plus.

How do the IP ratings compare?

The ABB IRB 390 FlexPacker is rated IP67. The FANUC DR-3iB is rated IP69K. Check wrist versus body coverage before washdown or dusty cells.

The verdict

The specs separate them here: the ABB IRB 390 FlexPacker carries more, 15 kg to the FANUC DR-3iB's 8 kg. If precision drives the job, the ABB IRB 390 FlexPacker holds the tighter repeatability at ±0.02 mm. They run different controllers, the ABB IRB 390 FlexPacker on the IRC5 / OmniCore and the FANUC DR-3iB on the R-30iB Plus, so whichever platform your team already programs and stocks parts for is a real tiebreaker. Mounting options differ: the ABB IRB 390 FlexPacker lists Inverted, and the FANUC DR-3iB lists Ceiling.

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 390 FlexPacker when

Very high pick rates for light items
Washdown-rated construction available
Larger work envelope than the IRB 360 family
Strong vision-guided picking integration

Watch for

Payload limited to light packaging items
Requires overhead structure for ceiling mount

Choose the FANUC DR-3iB when

Very high pick rates for light parts
Washdown-rated option for food and pharma
Small moving mass keeps cycle times low
Compatible with vision-guided picking

Watch for

Low payload limits use to light items
Ceiling mount requires overhead structural support

Controller ecosystem

Programming habits, spare parts, and pendant familiarity often decide the pick when payloads are close.

ABB IRB 390 FlexPacker

Brand: ABB
Controller: IRC5 / OmniCore
Class: delta

Service, spares, and pendant training for the ABB IRB 390 FlexPacker run through ABB's IRC5 / OmniCore stack.

FANUC DR-3iB

Brand: FANUC
Controller: R-30iB Plus
Class: delta

Service, spares, and pendant training for the FANUC DR-3iB run through FANUC's R-30iB Plus stack.

These arms run different controllers (IRC5 / OmniCore vs R-30iB Plus). 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 390 FlexPacker	FANUC DR-3iB
Mounting	Inverted	Ceiling
Robot mass	133 kg	170 kg
Protection (IP)	IP67	IP69K

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 390 FlexPacker is a delta arm rated 15 kg at 1300 mm with ±0.02 mm repeatability. The FANUC DR-3iB is a delta arm rated 8 kg at 1600 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.
