TRANSPORTATION AND INSTALLATION MANUAL
*4: The tone of the paint color may be different among production lots. It does not affect the product
quality, however.
!
CAUTION
Put 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 ball screw 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 PAYLOAD commands 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 with any objects. Even if Axis 1, 2, or 4 is moved at low speed, a collision or other
impact with an object can damage the ball screw spline (Z-axis shaft) before alarm occurs.
