R-50iA Controller - Enhancements

Powerful perforamance

Powerful Performance

Enhanced robot control performance has improved the signal output and sensor tracking on the robot’s motion path, enabling higher precision. This is a significant benefit for robotic applications such as dispensing and other demanding tasks that require exceptional robot path control.

Vision enhancements

Built-in Vision Enhancements

Improvements to FANUC’s built-in vision include an all-new camera design with five-million-pixel resolution – four times the current version, which significantly increases the robot’s field of view. In addition, easy unified GigE Ethernet communication ensures that the R-50iA camera is effortlessly linked to the Ethernet network. As a result, you can control the newly designed waterproof camera, complete with LED illumination, using just a single Ethernet cable.

FANUC’s integrated vision has a common vision user interface for the iPendant, TabletTP and PC, making it easy to use with any device.

Energy savings

Energy Savings

The R-50iA’s new 6-Channel amplifier is designed to be energy-efficient. It incorporates low power use elements, which minimizes energy consumption during robot operation. Additionally, low-power fans ensure efficient cooling of the controller without drawing excessive power.

A new eco mode switch is a user-friendly addition to the controller. By activating this switch, you can easily transition the robot into energy-saving mode. In this mode, the robot’s power consumption is further reduced, contributing to overall energy conservation and sustainability. These enhancements not only optimize the R-50iA controller’s performance but also align with eco-conscious practices.

R-50iA Controller - New Features

Cyber security

Cybersecurity

FANUC’s new R-50iA is the world’s* first robot controller to obtain third-party certification for international cybersecurity: IEC62443-4-1 and 4-2. It provides multiple layers of defense to secure data exchange, whether it’s file transfers (SFTP), or web communication (HTTPS), or IoT (MQTT TLS).

The R-50iA also includes password-based user authentication, simplifying the management of user groups in the field. This feature ensures authorized access while effectively preventing unauthorized entry.

Support functions

Robot System Setup Support Functions

The enhanced and flexible system setup functions make it easier to build automation systems and facilitate seamless integration with the robot. A key new feature of the new R-50iA controller, is the ability to execute Python scripts, which are widely used for system integration. By leveraging Python examples, system customization becomes more straightforward, allowing data output during program execution and ultimately saving valuable time and integration costs.

In addition, the R-50iA controller serves as a core element in automation systems. It supports software PLC functions adhering to international standards and communicates signal processes in six different languages, including ladder logic and structured text.
