#6449

Range 1 to 32767
Unit:

Pulse /rev.
Standard setting: 1024

Set the value before applying multiplication

for this parameter.

#6472

Range :

1 to 32767

Unit 1 = 1 rein-l

10 V at Solid Tap

Standard setting : 6000

( 10) Maximum Spindle Speed at Solid Tap

#6471

Range :

1 to 32767

1 = 1 rein-l

Standard setting : 4500

Set up carefully to maximum spindle motor
speed at solid tap.

It sets the acceleration time from the stop status
to number revolutions specified by #6471.
It is determined by motor torque and load. Refer
to Adjustment Procedure for Solid Tap Function
for YASNAC J50M

for setting.

Magnification of Spindle Position Error Area

#6155

Range 1 to 200
Unit

Standard setting: 120

It sets the area to detect excessive error of

the spindle at solid tap mode by the rate of
load to maximum spindle speed (#6471) at the
time of solid tap.

When the load correspond-

ing to 1.2, times maximum spindle speed is
applied at #6155=120, it causes alarm 346
SERVO ERROR(S) .

Spindle Error Detect ON Area

#6161

Area : 0 to 255

Unit 1 = 1 pulse
Standard setting : 50

It specifies the error detect area at R point
and error detect area at hole bottom ( Z

point ) at the start of solid tapping.

Z-axis Pull-in Area

#6476

Area : 0 to 65535

Unit 1 = 1 pulse
Standard setting : 1000

It specifies pull-in area of air cut area near
R point after solid tapping.

After complet-

ing distribution,

when residual movement of

Z-axis enters into this area, it cancels si-

multaneous feed of the spindle and Z-axis
and pulls Z-axis into R point.

Fine Adjustment of Spindle/ Z-axis Simulta-
neous Compensation Parameter

)

#6468 Range : -32768 to 32767

Standard setting : 0

This is the parameter for compensating for the
simultaneous operation of the spindle and Z-axis at
the steady-state cutting feed. Refer to Adjustment
Procedure for Solid Tap Function for YASNAC J50M
(DE8408877) for adjustment.

Spindle/Z-axis Simultaneous Compensation
Parameter

#6469 Range : 0 to 32767

Standard setting : 2000

This is the parameter for compensating for the

simultaneous operation of the spindle and Z-axis at
the time of acceleration/deceleration feed.
Refer

Adjustment Procedure for Solid Tap

Function for YASNAC J50M

for

adjustment.
