  (*1) Load specification of number 1 arm varies according to wrist load conditions and installation position.
  (*2) Note that the allowable moment of inertia of wrist varies with the wrist load conditions.
  (*3) JIS B 8432 compliant.
  (*4) Permitted height is not higher than 1,000m above sea level. If used in higher place, permitted temperature is affected by height.
  (*5) Software limits the downward vertical range of axis 5 to ±5°.
Axis 4 can move ±360° and axis 5 can move ±125° only when the encoder correction screen or the software limit settings screen is open.
Axis 4 can move ±360° and axis 5 can move ±125° only when the encoder correction screen or the software limit settings screen is open.
