Study notes

The standard type robot model is listed as SRA100B-01.
Listed applications include machine tending, material handling, palletizing, spot welding, and dispensing.
Allowable static load torque is 580 N·m on axis 4, 580 N·m on axis 5, and 290 N·m on axis 6.
Allowable moment of inertia is 45 kg·m² on axis 4, 45 kg·m² on axis 5, and 22.7 kg·m² on axis 6.
Installation is floor mounting.
The FD controller provides fourth-generation servo gun control software and pressure calibration up to 10 points.
The SRA series includes payloads from 100 kg to 240 kg, invert-mount models, long-reach models over 3 m, and a hollow-arm option for internal routing of spot-welding utilities.
For aluminum spot welding, the document states tip life of more than 400 welds between dress cycles.

Safety

Operating humidity range is 20 to 85%RH, with no dew condensation allowed.
Maximum installation altitude is 1,000 m above sea level.
Vibration at the installation face must not exceed 0.5G (+8 m/s²).
If the robot is used above the permitted height, the permitted temperature is affected by height; consult a Nachi-Flukoshi office.
