ABB IRB 6400 2.4/120 industrial robot with S4C controller

SKU: IRB 6400 M97A 2.4/120
control: S4C
capacity: 120kg
reach: 2.4m
stock: 4
weight: 2,100kg


The 6400 M97A (2.4m) is modular in construction and as standard the 6400 has 120kg capacity and 2.4m reach but there are several types available with capacities up to 150kg and reach up to 3.0m.
The S4C controller is a further development of the S4, the "C" stands for compact and indeed this type of controller is substantially smaller and lower than the original S4. The S4C controller is well regarded for its stability and reliability and has a very fast boot up time, much faster than many current models giving minimum downtime. Normally supplied with one I/O card giving 16 inputs and 16 outputs it can be fitted with many more if needed. Analogue I/O is also available. The controller can also work as a PLC by controlling and monitoring I/O signals. Up to 3 background programs (for monitoring signals for example) can be run in parallel with the actual robot program and even when the robot program has stopped. Outputs can be set at a specific time or distance before a programmed position and can be executed concurrent to the robot motion. The controller also has built in dual chain (0V and +24V) safety circuits meaning that the robot can be run without the need for extra emergency stop relays etc. Another benefit of the S4C controller over the S3 or S4 is that it is much easier to feed with data as it has an optional Ethernet connection. Thus it can easily be used with programs supplied by CAD-CAM software system that converts CAD models into robot paths.

The robot arm uses epicyclic (planetary) gearboxes for the major axis and is both simple and reliable. It should be noted that the arm is also very rugged and is less vulnerable to damage than many of its competitors. The robot is entirely powered by ac servo motors, the "rams" on the side of the arms are not hydraulic or pneumatic, they are simply enclosed mechanical springs. The springs and weight on the back of the robot make it very well balanced meaning the forces required to move the robot are remarkably small. Life expectancy or MTBF (mean time between failure) is largely dependant on service practises (once a year is normal) but we expect 6400's to last for at least 100,000 hours. Having said this we have seen very good examples with much more than this.
These are the main types of S4 controlled IRB 6400 model, prices can depend on the availability of a certain model, for example the 3.0m reach is comparatively rare:


120kg2.4mThe standard IRB 6400 model
150kg2.4mFitted with uprated axis 4 motor and modified parameters - some axis slightly slower
120kg2.8mFitted with 404mm extension in the upper arm and modified parameters to give increased reach - at the expense of payload and lower speed
75kg3.0mFitted with 606mm extension in the upper arm and modified parameters to give even more reach - at the expense of payload and lower speed
75kg2.25mThe IRB 6400PE "poke robot" designed to apply pressures up to 5000N has slightly shorter top arm, no balance weight and uprated motors
120kg2.9mThe IRB 6400S "shelf robot" designed to work below itself has a different module above axis 1 that changes the angle of the rest of the arm
The IRB 6400 is employed by the hundred around the world in a multitude of applications including spot welding, MIG welding, palletising, handling, pick and place, machine tending, milling, woodworking, cutting, de-burring, plastics, even NON EX painting and spraying applications. Our IRB 6400s are supplied complete with the arm, control cabinet (including I/O), cables and teach pendant. We clean, test and repaint them before shipping and if you need manuals we can provide them. Most of the ones we supply will have around 30,000 hours but this can vary - we are more focused on the robot's background and overall condition.
