10.9 Home Return
Operation and application
 The leading edge of the first home input
is set as a home position after the detection
of the leading edge of the near home input.
 Even when the limit input turns on, the
motor rotation will be automatically
reversed and the home return operation will
continue.
 This method is used when the home
switch exists in the range that the near
home switch is enabled, such as a system
using a servo motor. This method can also
be used when no home switch exists in the
range that the near home switch is enabled.
 The leading edge of a near home input is
detected and it is set as a home position.
 Even when the limit input turns on, the
motor rotation will be automatically
reversed and the home return operation will
continue.
 This method is used for performing the
home return with the near home switch
only.
 The leading edge of the first home input
in the home return direction set as a home
position after the detection of a trailing edge
(back end) of the near home input.
 Even when the limit input turns on, the
motor rotation will be automatically
reversed and the home return operation will
continue.
 This method is used when no home
switch exists in the range that the near
home switch is enabled.
 Moves the current position to the home
return direction, and stops at the position
where the rising edge of the home input is
detected. This coordinate is set as the
starting point.
 When no home input exists in the home
return direction, the limit input turns on and
the operation stops.
 This method is used for performing the
home return with the home switch only.
 Performs the home return based on the
home coordinate values in the axis setting
area of unit memories.
 Performs the home return toward the
home coordinate on the software.
 When the starting point is within the limit
switch, it cannot be started.
