What is the payload capacity and working radius of the FAIRINO FR20 cobot?

The FR20 handles a 20 kg payload, with a 25 kg max per its load curve. The effective limit depends on the payload’s center of gravity relative to the flange.

The FR20 has a 1,854 mm max TCP reach, with joint limits of: J1 ±175°, J2 +85°/−265°, J3 ±160°, J4 +85°/−265°, J5 ±175°, J6 ±175°. Some singular poses, like a fully contracted elbow or parallel wrists, are mechanically unreachable, limiting edge-case positions.

What is the precision and performance of the FAIRINO FR20?

The FR20 offers ±0.1 mm repeatability (ISO 9283) for precise handling. TCP speed reaches 2 m/s, with joint speeds of ±120°/s (J1–J3) and ±180°/s (J4–J6), enabling fast, smooth motion. Acceleration is user-adjustable (0–100%) to match industry application needs without compromising path quality.

The FR20 controller supports joint, linear, and circular moves (MoveJ/MoveL/MoveC/Circle) with real-time B-spline planning for smoother, low-jerk paths. Cornering uses configurable blending with a 0–1000 mm smooth radius and Acceleration Smooth Mode to maintain continuous motion and minimize settling.

What safety features and collaborative capabilities does the FAIRINO FR20 offer?

The FR20 has hardware E-stops on the button box and teach pendant that cut joint power and trigger an emergency stop. Category-0 stop times range from 170–700 ms and distances from 0.22–0.80 rad, measured with the arm fully extended at full speed (180°/s) and max load. 

The FR20 supports hand-guiding through Drag teaching mode, activated via the button box. An end-of-arm LED indicates states like Automatic, Manual, Drag, Start/Stop, Enable, and errors to aid operator awareness.

The FR20 supports force/torque-assisted dragging with singularity avoidance and offers collision detection via the FT_Guard command with configurable force and torque thresholds.

The FR series cobots are certified to ISO 10218, ISO 13849, and ISO/TS 15066 for functional safety, and hold CE, KCs, NRTL, RoHS 2.0, and IP54 product certifications, with IP65 available as an option.

What programming methods, development tools, and software environments are available with the FAIRINO FR20?

The FR20 is programmed via FAIRINO’s WebAPP, accessible from any PC or tablet at 192.168.58.2. The same interface is mirrored on the teach pendant.

The interface provides both graphical programming and Lua scripting for building tasks in one environment, with multilingual UI support. Programs are created by teaching points (via drag mode or button-box) or by coding directly using commands like PTP() in the editor. Lua is the native scripting language, with all commands and teach files written and run as Lua programs in the WebAPP.

The FR20 uses FAIRINO’s self-developed open platform, offering SDKs for C#, C++, and Python, and supports ROS / ROS 2 for integration with common tools and research stacks. The WebAPP also provides communication primitives (e.g., socket send/receive) for connecting to external systems via Lua. 

• SDK manual: https://fairino-doc-en.readthedocs.io/latest/SDKManual/index.html

The Controller Communication Protocol provides API access over TCP/IP for robot state, motion modes, I/O, and peripherals, enabling host applications to control the arm. The WebAPP also converts CAD-generated G-code (G0–G3) into Lua trajectories (MoveJ/MoveL/MoveC/Circle) for offline path planning and verification.

What connectivity and integration options are available on the FAIRINO FR20?

The FR20 offers 50+ connectivity options. The tool flange includes 2 DI, 2 DO, 1 AI, 1 AO, and a 24 V/1.5 A supply for end-effectors. The controller adds 16 DI, 16 DO, 2 AI, 2 AO, and two high-speed pulse inputs for cell-level I/O.

Standard networking includes Ethernet (TCP/IP) with Modbus TCP/RTU. Optional MiniPCIe boards enable CC-Link, PROFINET, EtherNet/IP, and EtherCAT fieldbuses.

The controller has two network interfaces with default IPs 192.168.57.2 and 192.168.58.2 for WebAPP access and device integration. The Safety Box connects via RJ45/PoE and mirrors the WebAPP on the plant network. For host control, the protocol supports UDP configuration for PLC/IPC links, including IP, port, cycle, and reconnect settings.

What is the mechanical design and build quality of the FAIRINO FR20?

The FR20 features an aluminum-steel arm with sealed IP54 joints (IP65 optional) and a compact 240 mm base. The arm weighs ~85 kg and can be mounted in any orientation. Noise is <70 dB during typical operation.

The controller has a galvanized IP54-rated chassis, measuring 245 x 180 x 44.5 mm and weighing 2.1–2.5 kg.

What installation and setup requirements does the FAIRINO FR20 have?

Install the FAIRINO FR20 on a rigid, flat base with at least 5x its weight capacity, high stiffness, and no resonance. Keep it structurally separate from moving equipment. Use six M10 (≥8.8 grade) bolts torqued to ≥45 Nm and two Ø8 mm locating pins. FAIRINO recommends mounting directly to solid ground due to the robot’s mass and inertia. If using a mobile platform or external axis, minimize acceleration.

FR20 model collaborative robot installation size

The FR20 uses either the AC Controller 5 kW or DC Controller 5 kW. Use a controller matched to site power: options include AC 100–240 V, 50–60 Hz, 10 A (2 kW) or AC 100–240 V, 50–60 Hz, 16 A (5 kW), with DC-input variants also listed; the robot must be electrically grounded and the control-box ground resistance ≤ 1 Ω. 

Use 4 mm² copper or 16 mm² aluminum conductors if no mechanical protection is provided. Install an upstream air switch and consider an EMC filter. Always isolate power and post a safety warning before wiring. For I/O power, the controller's internal 24 V supply (1.5 A max) is default; if higher load is needed, use the external 24 V supply (up to 2 A) via the “Power Communication” terminals per the schematic.

Robot wiring schematic diagram

Before first run, check all physical connections and grounding. Test the teach pendant cable, clean the control-box air filter, check terminal tightness, confirm mains connection, and ensure ground resistance is ≤1 Ω. Validate safety circuits by wiring redundant safety I/O and confirming Emergency and Safety Stop functions per your risk assessment. Power on only after all checks are complete and safety signage is removed.

What maintenance requirements does the FAIRINO FR20 have?

The FAIRINO FR20 requires 8+ maintenance procedures to retain mechanical fastening integrity, electrical safety, and functional stopping performance over monthly, semi-annual, and annual intervals. These include visual/mechanical checks of the arm, functional tests of safety circuits, and controller housekeeping performed with power isolated.

Controller / teach pendant / button-box checklist (E-stop, safety I/O, mode switching, pendant cable, control-box air filter, terminal tightness, ground resistance ≤1 Ω, and main power checks)

Note: F = Functional check, V = Visual inspection.

Operational maintenance (planned stops)

Power down, then inspect the robot–controller cable, base and tool-flange bolts, joint backs, rear covers, and rubber rings. Clean the arm with water, isopropyl alcohol, 10% ethanol, or 10% naphtha — avoid bleach. Minor grease at joints is normal and doesn't affect lifespan.

Preventive maintenance (monthly / semi-annual)

Test the Emergency Stop to ensure the robot halts and joint power cuts. Verify safety I/O, start/stop, and mode switching on the button box. Inspect the pendant cable. Clean the control-box air filter, check and tighten terminals, confirm main power, and ensure ground resistance is ≤1 Ω. Use a torque wrench to check base and tool-flange fasteners per install specs. Clean the controller interior with an ESD vacuum — do not use compressed air.

Comprehensive maintenance (annually)

Repeat full arm and controller inspections. Re-test Emergency Stop from both the pendant and button box. Recheck base and tool-flange torque, and verify controller power and grounding as before.

Skills and tools

With power off, perform operational cleaning and visual checks using hand tools and approved cleaners. Preventive tasks require a torque wrench, ESD vacuum, controller access for terminal and air filter checks, and ground resistance testing (≤1 Ω). Functional tests include E-stop activation and restart per procedure. Always isolate control-box mains before any work; never use compressed air inside the controller. Downtime results from required isolation, inspection, torque checks, and restart steps.
