(2) When the switch set up for deceleration turns the accel/decel LS signal ON,
the feed speed decelerates to the value set up in the “Approach speed”
parameter.
• Servo amplifier user constant (Cn-0022): [Zero-point approach speed 1]
(3) After the switch departs from the deceleration LS, the speed is changed to the
value set up in the “Zero-point return traverse distance” parameter at the
previous C-phase position.
• Servo amplifier user constant (Cn-0023): [Zero-point approach speed 2]
(4) By creep speed, the position to which the axes move (from the position at
which the C-phase pulse is detected) only the distance set up by the “Zero-
point return traverse distance,” is set up as the machine coordinate zero-
point.
• Servo amplifier user constant (Cn-0028): [Zero-point return final traverse
distance]
b. Zero-point Return Motion 2
Execute the zero-point return motion which is shown as follows. The position to
which the axes return is the zero-point of the machine coordinate.
(1) Starts moving in the direction designated in the “Zero-point return direction”
parameter. The speed at this point is the value set in the parameter “Fast feed
speed”.
• Setup parameter 1 (OWxx00): [Motion mode b9: Zero-point return direc-
tion]
• Servo amplifier user constant (Cn-0023): [Zero-point approach speed 2]
