Warning
The RACON controller performs magnetic-pole phase detection operation during the first servo ON processing after the
power has been turned ON. During this detection operation, the actuator will generally move by approx. 0.5 to 2 mm,
although the specific dimension varies depending on the ball screw lead.
(On rare occasions, the actuator may move by up to around one-half the ball screw lead depending on the position at which
the power is turned ON.)
If the power is turned ON while the actuator is positioned near a mechanical end, the actuator may contact the mechanical
end during the detection operation and reverse its direction.
Exercise due caution not to let the work part or hand contact any surrounding structure because of this movement and
sustain damage as a result.
