bit0: Switch ASIN calculation results range
Select the notation system for operation result of ASIN.
0: Do not switch minus figures to positive figures. (-90° to 90°)
1: Switch minus figures to positive figures. (270° to 90°)
bit1: Switch system variable unit
Select the unit for the system variable #3002 (cycle start operation time).
0: 1 ms unit
1: 1 hour unit
bit2: Switch G71, G72, G73 cutting direction judgment
Select the cutting direction when the longitudinal rough cutting cycle (G71), face rough cutting cycle (G72)
or closed loop cutting cycle (G73) is commanded.
0: Conventional specification
Determined according to the finished shape program.
1: Extended specification
Determined according to the finishing allowance and cutting allowance commanded in the program.
bit3: Facing turret mirror image coordinate value type
Select how to show the workpiece coordinate values of the axis for which the facing turret mirror image is
valid.
0: Movements in the workpiece coordinate system are in the same direction as those in the workpiece ma-
chine coordinate system.
1: Movements in the workpiece coordinate system are in the opposite direction to those in the workpiece
machine coordinate system.
bit4: Facing turret mirror image valid axis selection
Select the axis for which the facing turret mirror image is valid.
0: Fixed to 1st axis.
1: Determined according to the plane selected when the facing turret mirror image is commanded.
bit2: M98 sequence No. address selection
Select which address to use for calling a sequence No. in a sub program under sub program control (M98/
M198).
0: Address H is used for specifying the sequence No.
1: Address Q is used for specifying the sequence No.
bit4: Optional block skip operation changeover
Select the optional block skip operation.
0: Enable or disable optional block skipping in the middle of a block according to the setting of "#1226
aux10/bit1".
1: Enable optional block skipping at the top and in the middle of a block. Note that a slash "/" on the right-
hand side of equation or that in an equation between [ ] is handled as division operator.
bit5: Use of G54Pn for selecting extended workpiece coordinate system
Select whether to use G54Pn as a command for selecting an extended workpiece coordinate system.
0: Not use G54Pn as a command for selecting an extended workpiece coordinate system
1: Use G54Pn as a command for selecting an extended workpiece coordinate system
When 1 is set in this parameter, G54Pn is treated in the same manner as G54.1Pn.
bit7: Word range check
Select whether to check that the operation expression of the word data in the program is enclosed in brackets
[ ] when the machine program is executed.
This check is also applied to the 08000 to 09999 and the machine tool builder macro program.
0: Not check
1: Check
