This is the 400kg payload IRB 7600-400 with 2.55m reach.
The 7600 is designed for the high payload and high accuracy. Typically used for handling large loads the 7600 is also often used for high tolerance milling as the strength and stiffness of the arm is exceptional.
Characteristics such as high available torque and inertia capability, rigid design and powerful acceleration have earned this market leader its “Power Robot” title. A major concern with robots handling payloads of up to 630 kg will be to safeguard your personnel in the unlikely event of an accident, as well as to protect both the robot itself and your investment. ABB have therefore added a range of measures falling under the umbrella designator of Active Safety - and Passive Safety - system. The robot optimizes the acceleration and retardation, which results in shortest cycle time possible. Payload comes in several versions between 150 - 500 kg (up to 630 kg with “wrist down”). Max reach between 2.55 – 3.5 mm.
The M2000 S4C+controller, although cosmetically similar to the S4C it replaced is quite different internally. Where the S4C used ABB's own computer system (that is in turn very like the S4) the S4C+ has a PC style computer that allows greater connectivity and has much greater power than its predecessors. Similarities to the S4C include the servo drive system, the programming language and teach pendant. Incidentally the reason for the convoluted name was because Siemens had already trademarked the S5 name for their PLC systems! 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. Because of the controllers excellent connectivity it can easily be used with programs supplied by CAD-CAM software system that converts CAD models into robot paths.
At Global Robots we check, test and service each ABB IRB 7600 and they come with our 3 months parts warranty. The 7600 is quite rare on the used market, as not too many have been made and those are still mostly in their first application. For a high payload robot they are possibly the best, very quick and strong but based on standardised ABB modular design. Many high payload machines we see are virtually one offs whereas there are hundreds of IRB 7600 (but not the thousands like IRB6600's) this means that the IRB7600 is reliable and dependable.
