Current-limiting value during home return
The factory setting conforms to the standard specification of the actuator.
Increasing this setting will increase the home return torque.
This setting need not be changed in normal conditions of use. However, if an increased slide resistance causes
the home return to complete before the correct position depending on the affixing method, load condition or other
factor when the actuator is used in a vertical application, the value set in parameter No. 13 must be increased.
(Do not increase the value beyond 75%.)
Excited
-phase Signal Detection Direction
Following the power on, excited-phase detection is performed when the servo turns on for the first time. This
parameter defines the direction in which this detection is performed.
Normally this parameter need not be changed. In certain situations, such as when the actuator is contacting the
mechanical end or other obstruction when the power is turned on and cannot be moved by hand, change the
setting to the direction in which the motor can run easily.
To set a desired direction, set 0 or 1 in parameter No. 28, as applicable. If the detection direction is the same as
the home return direction, set the same value currently specified in parameter No. 5 [Home return direction].
To set the direction opposite the home return direction, set the value different from what is currently specified in
parameter No. 5 [Home return direction].
(Example 1) The power is turned on when the slider, installed vertically with the motor at the top, is contacting
the bottom mechanical end.
(Example 2) The power is turned on when the slider, installed vertically with the motor at the bottom, is
contacting the bottom mechanical end.
