(PR) #1271 ext07
bit0: Mirror image operation
Select the type of mirror image operation.
0: Type 1
- The program mirror image, external mirror image, and parameter mirror image are exclusive to each other.
- An increment command moves the image to the position indicated by the travel amount with the sign in-
verted.
1: Type 2
- Mirror image operation is enabled when the program mirror image (G51.1) command is issued or when
the external signal or parameter is ON.
- An increment command moves the image to the position determined by applying the mirror image to the
absolute program coordinates.
bit1: Address specifying fixed cycle repetition count (for M system only)
Select the address that specifies the fixed cycle repetition count.
0: Address L only (Default)
1: Addresses K and L
If addresses K and L are specified simultaneously, the data at address K will be used for operation.
bit2: F-command unit
(M system)
Specify the unit to be used if a thread cutting lead command contains no decimal point.
* This setting is independent of the input unit.
0: Type 1 (conventional specifications)
F1 : 1 mm/rev, 1 inch/rev
1: Type 2
F1 : 0.01 mm/rev, 0.0001 inch/rev
(L system)
Specify the unit to be used if a synchronous feed or thread cutting lead command contains no decimal
point.
0: Type 1 (conventional specifications)
[Input unit B] F1 : 0.0001 mm/rev, 0.000001 inch/rev
[Input unit C] F1 : 0.00001 mm/rev, 0.0000001 inch/rev
1: Type 2
F1 : 0.0001 mm/rev, 0.000001 inch/rev
* Type 2 is independent of the input unit.
bit3: G-code group for unidirectional positioning (for M system only)
Select the G-code group for unidirectional positioning.
0: Unmodal G code (group 00)
1: Modal G code (group 01)
Related parameter: "#8209 G60 Shift" (Set the last positioning direction and distance for each axis ap-
plicable when the unidirectional positioning command is issued.)
bit4: Operation by independent G40 command
Select whether the radius compensation vector is canceled by the independent G40 command.
0: Type 1 (conventional specification) (Default)
The radius compensation vector will be canceled by the independent G40 command.
1: Type 2
The radius compensation vector won't be canceled by the independent G40 command: it will be can-
celed by the next travel command for the radius compensation plane.
bit5: Cut start position (for L system only)
Select the position from where cutting begins in a fixed cycle for compound lathe.
0: Conventional specification (Default)
The cut start position will be determined by the final shaping program.
1: Extended specification
The cut start position will be determined from the cycle start point.
