Study notes

  • The document references an FD controller; no matching controller id is in the supplied reference list.
  • Applications listed are machine tending, material handling, palletizing, and spot welding.
  • Installation is floor-mounted.
  • Forearm payload is listed as 20 kg for the SRA133H.
  • Wrist allowable static load torque: J4 830 N·m, J5 830 N·m, J6 441 N·m.
  • Wrist allowable moment of inertia: J4 85 kg·m², J5 85 kg·m², J6 45 kg·m².

Safety

  • Ambient humidity must be 20–85%RH without condensation.
  • Vibration must not exceed 0.5G (4.9 m/s²).
  • Permitted height is not higher than 1,000 m above sea level; above this height, permitted temperature is affected by height.
  • Noise level is 79.6 dB(A) while operating at maximum speed with rated load.
