G76G78in-posn wdt.

Specify the in-position check width to be used for deceleration check of G0-G0 blocks in thread cutting cycle
(G76 or G78).
When this parameter is set to "0", or when the option "Programmable in-position check" is OFF, normal de-
celeration check method is applied.
---Setting range---
0.000 to 99.999 (mm)
0.0000 to 9.9999 (inch)
#8070

Turning cycle mode

1: If a zero-travel distance block is given during turning cycle mode (G90, G92 or G94), the turning cycle
is executed again.
0: If a zero-travel distance block is given during turning cycle mode (G90, G92 or G94), the turning cycle
is not executed.
#8071

3-D CMP (for M system only)

Set the value of the denominator constants for 3-dimensional tool radius compensation.
Set the value of "p" in the following formula.
Vx = i x r/p, Vy = j x r/p, Vz = k x r/p
Vx, Vy, Vz : X, Y, and Z axes or vectors of horizontal axes
i, j, k : Program command value
r : Offset
2 2
p =√(i + j
---Setting range---
0 to 99999.999
#8072

SCALING P (for M system only)

Set the scale factor for reduction or magnification in the machining program specified by G50 or G51 com-
mand.
This parameter will be valid when the program specifies no scale factor.
---Setting range---
-99.999999 to 99.999999
#8075 SpiralEndErr (for M system only)
Set the tolerable error range (absolute value) when the end point position, commanded by the spiral or con-
ical interpolation command with the command format type 2, differs from the end point position obtained from
the speed and increment/decrement amount.
---Setting range---
0 to 99999.999 (mm)
#8077 Invlute error
Set the tolerable error between the involute curve through the start point and the involute curve through the
end point.
---Setting range---
0.000 to 99999.999 (mm)
#8078 Screen Saver Timer
[M8]
Set the period of time before turn-OFF of the display unit backlight.
When "0" is set, the backlight is not turned OFF.
It is possible to turn OFF the backlight of the monitor screen as well by using the [SHIFT] + [C.B] keys, unless
its window is displayed.
---Setting range---
1 to 60 (min)
0: The backlight is not turned OFF
[C80]
Not used.
