*1. The maximum velocity in the chart is the maximum value.
It will change depending on the operation program and the wrist load condition.
*2. Depends on wrist load condition*3. JIS B 8432 conformance*4. Up to a maximum of 1000m from sea level. Ambient temperature is reduced
when allowable altitude is exceeded.
*5. Fluids that cause the deterioration of sealants, such as gasoline-based cutting
fluids, chlorine, alkalines, acids and organic solvents cannot be used. The main
robot cables are IP65.
