Study notes

  • Uses an AC servo drive system and articulated construction.
  • Applications listed: machine tending, material handling, palletizing, spot welding, dispensing.
  • Paired with Nachi FD controllers; no matching FD controller id is available in the reference list.
  • Hollow arm routes pneumatic, power, and servomotor cables internally, eliminating external dress packages.
  • SRA-H series payloads range from 100 kg to 220 kg and include floor-mount, invert-mount, and long-reach models over 3 m.
  • J3 and J4 rows list alternative ranges; the document does not clearly assign them to SRA100H-01 versus SRA133HL-01.
  • J2 range is listed as -1.40 to +1.05 rad but also as -60° to +60°; the source values are inconsistent.
  • JIS B 8422 compliant; sound level measured per JIS Z 9737-1 (ISO 11201).
  • Table lists 2,954 mm maximum reach for SRA133HL-01; additional information lists 2,654 mm reach for SRA100H.
  • Wrist payload column also lists 133 kg for SRA133HL-01; SRA100H-01 is 100 kg.
  • Forearm/Foresim load is listed as 20 kg.

Safety

  • Explosion proof is not available.
  • Humidity limit is 20–85% RH with no dew condensation allowed.
  • Installation-face vibration must not exceed 0.50 (4.9 m/s²).
  • Permitted installation height is not higher than 1,000 m above sea level; higher altitude affects permitted temperature.
