Full specifications

Performance

How much it lifts, how far it reaches, how precisely it repeats.

Payload Maximum mass the robot can carry at the wrist flange, including the gripper/tool. Higher means it can handle heavier parts.: 4 kg

8th pct in class
Reach Maximum horizontal distance from the base axis to the wrist — defines the size of the work area. Higher means a larger envelope.: 515 mm

5th pct in class
Repeatability How close the robot returns to the same taught point on repeated tries (ISO 9283, ±). Lower is better — tighter precision.: 0.02 mm

59th pct in class
Axes (DOF) Number of independently driven joints / degrees of freedom. 6 is standard for articulated arms; 4 for SCARA/palletizers; 7 adds elbow redundancy.: 6
Max TCP speed Top linear speed of the tool centre point. Higher means faster cycle times.: 9,000 mm/s

62th pct in class

Physical

Size, mass and how it mounts.

Robot weight Mass of the manipulator (arm) without controller. Lighter eases mounting and mobile use; heavier often means stiffer/higher payload.: 22 kg
Mounting Orientations the robot can be installed in (floor, ceiling/inverted, wall, tilted, mobile base).: floor, ceiling, wall

Power & controller

Electrical supply and the control cabinet that drives it.

Power supply Required input voltage / phase for the controller.: 3-phase 200 V AC
Controller The control cabinet / unit that runs the robot.: CR800

Environment

Conditions it can operate in — dust, water, temperature, cleanliness.

IP rating (arm) Ingress protection of the body against dust/water (IEC 60529). First digit = dust, second = water. Higher resists harsher environments.: IP40

9th pct in class

Safety

Standards met and collaborative-operation capability.

Collaborative Whether the robot is designed to work safely next to people without fencing (power-and-force-limited).: No
Safety standards Certified safety standards (ISO 10218-1, ISO/TS 15066) and functional-safety level (PLd/PLe, SIL2/3).: ISO 10218-1

Control & software

Programming, languages and ecosystem.

Programming How the robot is taught: pendant, hand-guiding (lead-through), block/flow-chart, scripting, offline simulation.: teach-pendant, offline-programming
Languages Native robot programming language(s) — e.g. KRL (KUKA), RAPID (ABB), URScript (UR), INFORM (Yaskawa).: MELFA BASIC VI
Teach pendant The handheld programming/jog device supplied.: R87TB / R56TB pendant
Simulation Offline programming / simulation software for the robot.: MELFA-Works (RT ToolBox3)
Offline programming Whether programs can be built and validated offline in a digital twin before deployment.: Yes

Connectivity & I/O

Signals, fieldbuses and tooling interfaces.

Fieldbus Industrial networks supported for PLC/cell integration (PROFINET, EtherNet/IP, EtherCAT, Modbus TCP, CC-Link, etc.).: PROFINET, EtherNet/IP, CC-Link IE, Modbus TCP
