Epson Releases RC620 Robot Controller

Epson Releases RC620 Robot Controller
– Work cell controller provides full control over entire robot automation systems –

Seiko Epson Corporation (“Epson”, TSE:6724) announced a new controller for use with Epson industrial robots. An upgrade from Epson’s current RC180 controller, the new RC620 is capable of driving almost all Epson industrial robot models*1. With functions that allow it to fully control entire robot automation systems, including robots and peripheral equipment as well as multiple manipulators, the RC620 acts as a work cell controller, providing greater flexibility for building a diverse range of systems. The RC620 robot controller will begin shipping at the end of October.

Product features
1.A wide variety of systems can be built by using multiple manipulators and additional axis functions.

  • The RC620 drives two SCARA robots (8 axes) and, with the addition of drive units, up to 16 manipulators (20 axes).
  • An Epson linear axis or a drive axis of another supplier can be added as a travel axis, and pallet definitions that include the additional axis can be created, so even a large automation system with a large working envelope can be built using small robots, thus improving space efficiency.

2.High expandability. A wide variety of options can be added to this powerful, PC-based controller, making it easy to provide the flexibility needed to meet a diverse range of applications for entire robot systems. Its open architecture means off-the-shelf PC hardware and software can be used.

3.High-speed conveyor tracking enables rapid pick-and-place of fast-moving parts and products.

4.A high-resolution image processing option boosts positioning and alignment accuracy.

5.Fieldbus master: A variety of fieldbuses act as masters or slaves so that data can be freely exchanged with peripheral equipment.

6.Background tasks: Even when an emergency stop switch is pressed, a safety door is opened, or an error is issued, tasks that are being executed by the program and that do not involve robot movement can continue, so peripheral equipment can be monitored and communications with other controllers can be processed.

7.Data acquired from peripheral equipment (e.g. inspection systems, measuring instruments, and sensors) are saved in a file and can be used as process control data, etc.

8.One-push back-up
The status of the controller and manipulators can be saved in a file in USB memory with a single push – great for analyzing errors and quick restoration of operations.

9.GUI builder:Users can easily create custom operator windows without using a special display device or PLC.
