- On controller display, axis 1 to 4 is displayed as J1 to J4 for each.
- The specification and externals described in this specification might change without a previous notice for the improvement.
- The explosion proof specification is not available.
*1: The Allowable moment of inertia of a wrist changes with load conditions of a wrist. *2: Permitted height is not higher than
1,000m above sea level. If used in higher place, permitted temperature is affected by height. *3: Liquid such as organic
compound, acidity, alkalinity, chlorine or gasoline cutting fluid which deteriorates the seal material are not available to use. *4:
The "Max. speed" in this table is the available maximum value and will change depending on the work-program and the wrist
load condition. *5: Secondary tube φ4 is a set of solenoid valve option. *6: LAN cable (8core) can be used for auxiliary
wires. *7: This is a maximum pushing down force at tool top point when maximum payload is mounted and axis 1, 2 and 4
does not move. Please use robot under specified limit. In case that continuous pushing down force is applied, overload error
may occur. Please use robot under the condition of which no overload error occurs.
