Initial countermark position
Corresponding to the
slider position of 2 mm
away from the mechanical
end
10) Move the slider to a position where Z-phase turns on (home position).
On both standard actuators and actuators whose home is set on the opposite side, this position
corresponds to 2 mm from the mechanical end.
Warning: If the actuator is installed vertically, move it after turning on the controller power and
forcibly releasing the brake. At this time, beware of danger as the actuator may
drop suddenly.
Always provide a support to brace the actuator hand to prevent sudden drop, so as
not to pinch fingers or damage the work part.
11) Check the following points before restoring the home position:
� The motor side should be aligned with the initial countermark. If the position is offset, adjust it to achieve
proper alignment.
� The ball-screw side should be in a location corresponding to the slide position of 2 mm away from the
mechanical end.
After the check, attach a new belt while holding the pulleys on both sides in position.
