Make sure the current-limiting value remains 20% or more.• The graphs assume a traveling speed of 10 mm/s for RA8C/RA8R/RA10C/RA10R and 20 mm/s for other than those models duringpush-motion operation.• Be sure to use the RA8C/RA8R at a current-limiting value of 60% or less, because performing push-motion operationwith these actuators at a current-limiting value of 70% may lead to motor damage.• Use the table below as a rough guide for the upper limit of push cycles when the RCP5-RA10C/RA10R of each lead is operated with themaximum push force over a push-motion travel distance of 1 mm.Lead (type) Push cycles2.51.4 million cycles5 1025 million cycles 157.6 million cycles* The upper limit of push cycles varies depending on the impact, vibration and other operating conditions.The cycles shown to the left assume no impact or vibration.Points to Note on Push-motion Operation Using RCP5-RA10C/RA10RThe push force is limited on certain RA10C/RA10R models due to its relationship with the buckling load of the ball screw.
