Factors to consider when selecting FANUC robots:
1. Application Scenarios
– Welding, handling, assembly, spraying, palletizing, polishing, die-casting, etc. (Different processes correspond to different series).
– Example: Die-casting island loading and unloading requires high-temperature protection, welding requires matching welding machine interfaces.
2. Load and Workpiece Parameters
– Workpiece weight + end tool (fixture/suction cup) weight + 20% safety margin.
– Example: Handling a 100kg mold, fixture 30kg → requires a model with a load capacity of ≥130kg.
3. Working Range
– Horizontal Radius (Reach): Maximum coverage distance (e.g., 3 meters).
– Vertical Stroke (Z-axis): e.g., 1500mm lifting requirement.
4. Accuracy and Speed
– Precision assembly requires ±0.02mm high accuracy, while general handling can relax to ±0.1mm.
– High-speed production lines require high cycle times (e.g., ≤10 seconds per cycle).
5. Environmental Conditions
– High temperature, dust, humidity, etc. (e.g., die-casting island requires IP67+ high-temperature coating).

II. Key Selection Steps
Step 1: Match Load and Reach
– Load reference table:
| Load Range | Recommended FANUC Series | Typical Models | Reach |
|————–|————————-|———————–|—————|
| ≤10kg | LR Mate Series | LR Mate 200iD/7L | 0.9-2.2m |
| 10-50kg | M-10iD/M-20iD Series | M-20iD/35L | 1.4-2.8m |
| 50-300kg | M-710iC/M-900iA Series | M-710iC/70L (70kg) | 2.0-3.1m |
| Over 300kg | M-2000iA Heavy Series | M-2000iA/1200 (1200kg)| 2.5-3.7m |
– Example:
– Requirement: Load 130kg, reach 3 meters → select M-710iC/70L (dynamic load needs verification) or M-900iA/200L (200kg, 3.2m reach).
#### Step 2: Function Configuration
– Control System:
– Standard: R-30iB Plus controller.
– Advanced: Force control (Force Sensor), vision (iRVision) optional.
– End Interface:
– Digital I/O, Ethernet/IP protocol (communication with fixtures/PLC).
#### Step 3: Environmental Adaptation
– Protection Level:
– General workshop: IP54.
– Die-casting/Spraying: IP67 + explosion-proof/high-temperature options.
#### Step 4: Simulation Verification
– Use FANUC ROBOGUIDE software:
– Import robot model and production line 3D layout.
– Check for interference, cycle time, and reachability.

### III. Selection Tools and Resources
1. Official Selection Tools
– FANUC Robot Selector: Online input parameters to automatically recommend models.
– Load Calculation Table: Contact suppliers for dynamic load verification tools.
2. Documentation Reference
– Download FANUC model manuals (e.g., “M-710iC Series Specifications”) to confirm detailed parameters.
3. Supplier Support
– Provide application scenario videos or drawings, FANUC agents can customize solutions (e.g., special reach or protection).
—
### IV. Common Mistakes to Avoid
– Error 1: Ignoring dynamic load (impact force may exceed limits during acceleration/deceleration).
– Solution: Use load at 80% of rated value (e.g., for a 70kg model, actual load ≤56kg).
– Error 2: Insufficient reach.
– Solution: Reserve a 10% margin (if 3 meters radius is needed, select a 3.3m reach model).
—
### V. Typical Application Selection Examples
#### Case 1: Handling in Die-Casting Island (100kg Workpiece, 3m Radius)
– Selection:
– Model: M-710iC/70L (70kg load, 3.1m reach).
– Configuration: IP67 protection + high-temperature fixture + ROBOGUIDE simulation.
– Alternative Solution: If load exceeds limit → M-900iA/200L (200kg, 3.2m reach).
#### Case 2: Automotive Welding (50kg Welding Gun, ±0.1mm Accuracy)
– Selection:
– Model: ARC Mate 120iD (20kg load, optional welding machine interface).
– Configuration: Welding software package + anti-spatter shield.
