Filling Grease to Ball Screw Spline Unit and Replacement

The ball screw spline unit is to be replaced by our service engineer. If it is replaced by
the customer, we will not guarantee any consequential trouble or accident.
• The ball screw spline unit should be replaced with a new one only after the controller power
supply plug is removed. If the work is done while the power is connected, you may get an
electric shock or the robot may malfunction, which is very dangerous.
• Because the timing belt, nut and pulley are disconnected, the mechanical home point shifts
and proper control cannot be done. To avoid this, home return operation is necessary after
replacement of the ball screw spline unit. For the home return procedures, see "Section 7,
Robot Home Point and Position Detector Error."
