Features

01Further Cost Reduction Based on the RCX340 Platform

Changing the rotational sensor from a resolver to an encoder eliminates the need for a signal conversion circuit, reducing both component count and overall cost.

02Reduced Startup and Commissioning Time

By relocating the absolute encoder backup battery to the robot, the number of required batteries is reduced, lowering maintenance costs.

03Compliance with International Standards and Safety Certifications

We are continuously working to ensure compliance with applicable regulations and safety standards in the regions where our products are sold.
