11.1 Types of Home Return
11-7
Limit method 1 (Limit signal + Z phase)
• 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.
• In the case of the limit method 1, the operation stops once in the home return deceleration
time after the detection of the trailing edge of the limit input as the home return positioning
control mode (Method33/34) of Servo Amplifier A6B/A5B is used. The home position is
searched at a home return creep speed again, and the operation stops when the leading
edge of the first home position (Z phase) is detected.
(Note): The home return positioning control mode (Method33/34) of Servo Amplifier A6B/A5B is a mode to detect an
index pulse as a home position. The home return direction of Method33 is the - direction, and that of Method34
is the + direction.
