Editor's notes
Unverified (free text): official-product-page. Page accepts 24 V or 48 V input; 48 V recorded as the nominal used for the speed figures. The RobotShop page is internally inconsistent (nominal power 166 W vs 300 W; backlash 3.5 vs 5 arcmin). Peak torque not stated ("torque increased by 20%"). Group F recorded the RMD-X8-P20-120-E (43/120 Nm, EtherCAT) from OpenELAB as the headline variant; this pass found the Pro V2 1:9 CAN at RobotShop — the editor should pick one representative variant. Company EtherCAT membership supports `industrial_bus: true`.
