EPSON RC620 Robot Controller

Controller with PC

RC620 is the optional controller of the C, G, RS and S-Series robots. The RC620 is a robot controller and a Windows-based industrial PC, in one box. The robots are connected to the controller. All programming is done on the controller, and communication with other parts of the robotic cell are also done through it. The RC180 includes everything that is needed to operate the robot, and its capabilities can be extended with various options.

Limitless possibilities

The RC620 can do everything that the RC180 can, and a lot more. The RC620 can control up to 4 different robots. By connecting an external display, keyboard and mouse, programming is done directly on the controller. It can also be used as a Fieldbus master communications unit.

Simple to understand programming language: SPEL+

EPSON robot programming is done in a Windows-based programming environment called EPSON RC+. The programming language itself is called SPEL+.
SPEL+ is very similar to BASIC. It is quick to learn and easy to understand. After programming and compiling in EPSON RC+, the program is transferred to the robot controller. From that point, the controller controlls the robot (without the need of the PC).

Do you need to control other devices as well? No problem. SPEL+ can do a lot more than just robot control. It is a multitasking language, capable of controlling task parallel or independent of the robot.

Complex motion control

SPEL+ includes a wide range ot motion commands: PTP (point-to-point motion), linear motion, CP (continuous path motion), etc. or special motion commands such as Jump or Palletizing commands.

Robot Simulator, to plan ahead

With the use of the 3D robot simulator, you can plan ahead, design and simulate your application before your robot even arrives. Inside EPSON RC+ you can add 3D models to model your robotic cell, and check the cycle times. You can run study and verify your concept ideal before having to manufacture anything.

Camera System

CV1, Compact Vision

For vision applications you can use EPSON's own smart camera system. It connects to the robot controller simply through an Ethernet network, and its prorgamming is fully integrated into the EPSON RC+ robot programming environment. For standard camera applications we offer the CV1 Compact Vision system with support up to 2 cameras.

The CV1 can be ordered with 2 different types of cameras: the standard camera (640 x 480 pixels) and a higher resolution camera (1280 x 1024 pixels), for mobile and fixed applications. For maximum flexibility and a perfect fit for your needs, we offer different size lens for the cameras.
