(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]
