*1 This assumes a speed at the rated motor revolution (3,000min
-1
).
*2 The maximum load capacity assumes the capacity at the rated speed under 0.5 G for horizontal and wall mounts,
and 0.3 G for vertical mount.
*3 The maximum speed is the value restricted by the motor rotational speed (at 3000 min
-1
) or by the permissible
rotational speed of the ball screw.
