2.7 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 is turned off with the power supply plug removed. If the work
is done while the power is turned on, 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 4.
