Communication with external equipment or integration
of fi eldbus networks — the expansion cards provide
diverse options to fl exibly expand your system accor-
ding to your requirements and at a low cost.
RS-232C serial interfaces
The standard controller is equipped with an RS-232C port. For expansion,
we offer a further serial expansion card with four additional interfaces.
Expansion I/O cards
If the 24 standard inputs and 16 outputs are not enough and you do not
want to set up a fi eldbus network, 32 inputs and outputs can be added to
your system for every card. You can use a total of up to four expansion
cards.
Fieldbus card
Is your installation already provided with a fi eldbus system or do you wish
to reduce the effort for establishing further connections? Then you can use
the following master and slave card options for different bus systems: Profi -
bus, DeviceNet, CC-Link and Ethernet IP. Depending on your requirements
they can also be combined.
In many fi elds of robot-assisted automation, Conveyor
Tracking has become indispensable. The reason is
obvious: With a vision system, objects on conveyors
are detected even in chaotic positions so that the robot
can pick them up while the conveyor keeps running.
To allow that, Machine Vision, Conveyor Tracking and
robot must be one unit without any interface problems.
A real Epson challenge.
More fl exibility
An encoder constantly measures the conveyor motion. Even if speed chan-
ges between detection and handling of an object, the robot can accurately
grip or position the object.
Multi-conveyor and multi-robot: The RC620 supports up to 16 conveyors
which can be freely combined with all robots connected to the control in
Conveyor Tracking. Another advantage: Objects found on the conveyors
are arranged in intelligent queues. These are then handled by multiple
robots and there is no need for the operator to interfere.
Sensor Tracking
Sensor Tracking is another, cost-effective possibility for Conveyor Tracking
if all parts are on a zero track on the conveyor. Instead of detecting the
object position by camera, Conveyor Tracking is triggered by a sensor, e.g.
a light barrier. When the object enters the robot pick-up area, the robot can
accurately pick it up.
Pulse generator
The PG board mainly serves to read conveyor speed for Conveyor or
Sensor Tracking via an encoder. In combination with corresponding further
software options it can also be used to control kinematics not consisting of
Epson components. Stepper as well as servo motors are supported.
