At Mitsubishi Electric ”switchgear cabinets” are
relics of the past – everything is now packed into a
single compact controller. Depending on the robotmodel either
the CR1 controller with a footprint no larger than an A4 sheet
of paper or the CR2/CR3 controller is used.The powerful control
performance is the same in both the smaller and larger versions.
The only difference between the two is in the power output
stages. No matter which controller you use you always work
with the same
programming language – MELFA BASIC IV – and
have the same options at your disposal.
This transparent compatibility
pays offwhen you need to use different robot types or models
when the needs of your application change. The impressive
performance specifications of
these controllers speak for
themselves.
Number-crunching power
A 64-bit RISC processor with DSP provides ample power for
3-D circular and linear interpolation and for multitasking
with up to 32
programs running in parallel.
Gentle joining
The standard ”compliance control” function guarantees
gentle positioning. This function can be activated and deactivated
as required,
making it possible to optimise
demanding joining and
assembly processes, saving
wear and tear on both
components and robots.
Sensorless collision monitoring
Potential collision situations
are identified reliably without
an additional sensor,
preventing damage to both
workpieces and peripherals.
Work space limitation
You can define multiple ”no go” areas within the
robot’s work space that the robot is not permitted to
enter, even in teaching mode. This makes it possible to protect
the product being manipulated and the robot from dangerous
collisions.
Digital inputs and outputs
In their standard
configurations the CR1 has 16
digital inputs and 16 digital
outputs, the CR2/CR3
32 digital inputs and 32 digital
outputs. Optional remote I/O boxes make it possible to increase
this to up to 256 inputs and 256 outputs for complex applications.
Large program memory
The controller can store up to
88 independent programs, all
of which can call each other,
for example when different
program sequences are needed for different products.
Teaching Box:
The convenient
Teaching Box is used for
manual entry of the
working positions of the
MELFA robot. It also has
functions for testing the
entire programmed
movement sequence
after it has been
entered. |
