The GMFanuc Model S-420 is a six-axis articulated arm, electric servo driven robot. All six axis motions are controlled simultaneously.
S-420 Drive Description
Axes 1, 2 and 3 of the S420 are driven by AC servo motors through RV reducers. The motors are directly connected to the reducer and the driving force for the axis is supplied directly from the output of the RV drive. This direct connection of the RV drive allows for fewer drive train members, more rigidity and smoother motion. Wrist axes (4,5, and 6) are also powered by AC servomotors through RV reducers. The motors are located at the rear of the third axis and transmit power to the wrist through torque tubes. The motors are connected to the torque tubes through a set of precision high speed gears. The wrist end of the torque tube on axis 4 is directly connected to the output of the RV drive, The wrist end of the torque tube for axes 5 and 6 connect to the input of the RV reducer through a second set of precision gears. For all three axes, the output of the reducer is directly connected to the axis member All six axes utilize electro-mechanical brakes at the motor side of the axis drive train.
Capacity
The S-420 can manipulate 120kg (264 lbs.) payloads with a center of gravity located 240mm, (9.45”) from the face of the wrist flange and with a 300mm (11.8”) offset from the wrist center line Repeatability: ±0.5mm (±0.02”) at maximum speed and extension. Approximate weight: Mechanical unit = 1600kg (3520 lbs.)
