How does MELFA SafePlus enable collaborative operation on an industrial robot?

The RV-FR Series is not a lightweight cobot—it is a full industrial robot with collaborative safety functions layered on top. MELFA SafePlus provides Safety-Limited Speed (SLS), Safety-Limited Position (SLP), Safe Torque Off (STO), Safe Stop 1 and 2 (SS1/SS2), and Safe Operation Stop (SOS). These functions restrict the robot's speed and work envelope when an operator enters the shared workspace, then restore full performance when the zone is clear. Safety logic is configured per I/O without requiring a separate safety PLC. The advantage over purpose-built cobots is that when collaborative mode is not needed, the robot runs at full industrial speed—cycle times as low as 0.32 seconds on the RV-7FR.

What payload and reach options does the RV-FR Series cover?

The lineup spans 13+ models from the 2 kg / 504 mm RV-2FR to the 80 kg / 2,100 mm RV-80FR. Mid-range models (RV-7FR, RV-13FR, RV-20FR) cover the 7–20 kg sweet spot for assembly, machine tending, and packaging. Long-arm variants (suffixed L or LL) extend reach without increasing payload. All models share the CR800 series controller architecture and MELFA Smart Plus functions including force sensing, predictive maintenance, and autonomous calibration.

What environmental variants are available?

Standard models carry IP40 rating. Oil-mist versions (IP67) suit machining environments. Cleanroom models meet ISO Class 3 for semiconductor and medical applications. ESD-compliant, ATEX Zone 1/2, and food-grade (FDA-compliant coating) variants are also available—making the RV-FR one of the broadest single-platform robot families for regulated manufacturing environments.
