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
Limit (+)
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
Limit (+)
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.
Limit (+)
● 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 leading edge of the
home input is detected. This coordinate
is set as the starting point.
Limit (+)
● 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.
This method is compatible with the F171
