10.3 Limit Switch
Normal home return operation uses the “stopper method” wherein the slider contacts the stopper and reverses,
after which the Z-phase is detected and defined as the home. The home limit switch (L) is an option which is
designed to perform this reversing operation using a proximity sensor, not a stopper. Use the home limit switch if
you want to increase the reliability of home return by, for example, preventing a false detection of mechanical end
due to contact with other device, etc.
If this option is selected, three proximity sensors are installed, including the home detection sensor (HOME),
overtravel sensor on front side (+OT) and overtravel sensor on motor side (-OT). (HOME and -OT are integrated
as twin sensors.) Take note that moving the home sensor significantly may shorten the stroke.
The standard installation position of the home limit switch and cover is on the right side of the actuator as viewed
from the motor, represented by the option model number “L.” If you want to have the limit switch on the right side,
specify the option model number “LL.”
