Cause the rod to project 2 mm from the mechanical end.
Apply countermarks once the rod has
projected 2 mm from the mechanical end.
[Procedure]
1) Move the rod to a position where Z phase turns on (home position).
This corresponds to a position where the rod projects 2 mm from the mechanical end.
Apply countermarks in this position.
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 load.
2) Using an Allen wench of 2 mm across flats, remove the two motor-unit affixing bolts on the right and
left.
