STE 73995– 74 –TRANSPORTATION AND INSTALLATION MANUALPosition detection method Absolute*1: When the mass of load exceeds 1 kg, or when the gravity center position of loadis away from the axis 4 center position, both the speed and acceleration shouldbe reduced, using the PAYLOAD command.*2: Shuttle time for rough positioning in horizontal direction of 300 mm and verticaldirection of 25 mm.! CAUTIONPut the Z-axis (axis 3) in the raised position as much as possible, when moving Axes 1, 2, and 4.Moving Axis 1, 2, or 4 when the Z-axis is in low positions can lead to premature damage to the ballscrew spline (Z-axis shaft).If Axis 1, 2, or 4 must be moved while the Z-axis is in low positions due to unavoidable circumstances,prevent the ball screw spline vibrations by using the SPEED, ACCEL/DECEL, and PAYLOADcommands to adjust the operation speed and acceleration.If Axis 1, 2, or 4 is moved while the Z-axis is in low positions, be extremely careful not to collide withany objects. Even if Axis 1, 2, or 4 is moved at low speed, a collision or other impact with an objectcan damage the ball screw spline (Z-axis shaft) before alarm occurs.
