the coordinate to zero. The following ten home return methods are available for FP7 MC Unit.

Operation overview
The leading edge of the first home position (Z
phase) is set as a home position after the
detection of the leading edge of a near home
input (HOME).
The leading edge of a near home input (HOME)
is detected and it is set as a home position.
The leading edge of the first home position (Z
phase) in the home return direction set as a
home position after the detection of a trailing
edge (back end) of the near home input (HOME).
The trailing edge (back end) of a near home input
(HOME) is detected and it is set as a home
position.
Reverses after detecting the leading edge of the
limit switch on the opposite side of the home
return direction. After that, the operation stops at
the first leading edge of the home position (Z
phase). It is set as a home position.
Detects the leading edge of the limit switch in the
home return direction and stops. It is set as a
home position.
Moves the current position to the home return
direction, and stops at the position where the
leading edge of the first home position (Z phase)
is detected. It is set as a home position.
Stops by a mechanical stopping mechanism as a
stopper. A position when a constant time elapses
at a torque value larger than a specified value is
set as a home position.
Although the operation is similar to the stop-on-
contact method, the first position where the Z
phase is detected is set as a home position by
performing the reverse operation after the stop by
a stopper.
The current value is set as a home position.
