DOG method 1 (Based on front end + Z phase)
• 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).
• In the case of the DOG method 1, the operation stops once after the detection of the leading
edge of a near home input (HOME) 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 Method 34
is the + direction.
