1[rad] = 180/π[°], 1[N･m] = 1/9.8[kgf･m]*1：Load specification of number 1 arm varies according to wrist load conditions andinstallation position.
*2：Note that the allowable moment of inertia of wrist varies with the wrist loadconditions.
*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.
