(1) When the stroke increases, the maximum will drop to prevent the ball screw from reaching the critical rotational
speed. Use the actuator specification table below to check the maximum speed at the stroke you desire.
(2) The load capacity is based on operation at an acceleration of 0.3G (0.2G for 2.5mm-lead model). These values are the upper limits for the acceleration.
(3) The values for the horizontal load capacity assume the use of an external guide, so that there is no external
force from any direction other than the forward/backward direction of the rod.
(4) Please note that there is no brake option for the motor built-in specification.
(5) See page A-71 for details on push motion.
