5.2.10 FEED STOP

BY SENSOR

SIGNAL

Turn on the sensor stop switch, to receive the
sensor input signal necessary for centering, groove

width detection step difference designation, and
then to stop.

When the sensor input is on,

operation is not made in the approaching direction,

only in the leading direction.

Therefore,

centering, groove width detection etc.

can also be performed by using this function and

the numerical setting function.

Notes :

(1) The axis that stopped by sensor input will not

move unless once returned in the opposite
direction.

Set this axis return distance in parameter #6578.

set this parameter to prevent sensor

chattering, 1 = pulse)

(2) The sensor stop function is

when the

mode is changed to the automatic mode.

For

safety, it is recommended to keep the sensor away
from the

when changing the mode to

automatic mode.

5.2.11 MANUAL CENTERING FUNCTION

(1)

Call

up the manual mode.

(2)

Select the current screen. “Universal, ”

the X axis and place the sensor on the

circumference of the circle.

The feed stops when

the sensor generates a signal, and the value stored
in (4) is set up at that point.

(6) Move the axis in the opposite direction, and

place the sensor on the circumference of the
reverse side.
The feed stops when the sensor generates a signal,

and the center of the two

points touched

by the

sensor is set up.

5.2.12 SPINDLE INDEXING FUNCTION

The spindle indexing function is a function that
stops the spindle at an optional position (a position
with an optional rotary angle) .

5.2.12.1 ADDITIONAL CONDITIONS FOR THE SPINDLE
INDEXING

The spindle indexing function must be understood

well, and the conditions consolidated before use.

(a) The S5-digit analog output option must be

incorporated.

(b)

must be mounted on the spindle

drive.

motor, and the gear ratio

to be used

at 1 : 1. (The

best performance is gained when the spindle and the
motor are direct-link type).

(d) The number of feedback pulse per spindle rotation

must be 4096.

(e) The solid tap function option must be validated.

5.2.12.2 RELATED PARAMETERS

The following parameters must be preset to use the spin-

dle indexing function. If any change is made to the para-

meters, be sure to turn off the power once.

(1) Spindle PG mounting position

#6065 D7 1: Motor side

Spindle side

Note :

This parameter is used to link the spindle and the

motor with the gear.

Set “O” to use the spindle

indexing function.

(2) Gear ratio of spindle and spindle motor

#6198

Spindle side gears

#6199

Motor side gears

Setting range : to 127

Note :

Set the gear ratio when linking the spindle and
spindle motor with the gear.

Set

both #6198

and #6199 when using the spindle indexing
function.

(3) Spindle feedback magnification
