Toshiba TH Series Instruction Manual page 77

*2: Shuttle time for rough positioning in horizontal direction of 300 mm and vertical
direction of 25 mm.
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.
