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.
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.
