BARRIER bit settings (7 bits)

1. bit 0

   Output of tool change preparation M code (M109/M249) when executing tool change

   0: Not output 1: Output

   Range 0, 1 · Takes effect: Immediate

2. bit 1

   Fixed value

3. bit 2

   Fixed G0 inclination control in the G68/G68.5 mode

   Select the inclination to be used for fixed G0 inclination control (option) in the G68/G68.5 mode when parameter M1 (rapid feed rate) and parameter N1 (rapid-feed time constant) are used. 0: Uses the minimum inclination among the actual axes after G68/G68.5 conversion. 1: Uses the minimum inclination among the virtual axes before G68/G68.5 conversion. (*) * If the move command specifies one axis, the inclination of the specified axis is used.

   Range 0, 1 · Takes effect: Immediate

4. bit 3

   Selection of whether or not to measure the milling tool length with the tool measuring unit

   Select whether or not to measure the milling tool length with the tool measuring unit. 0: When a milling tool is selected, its length is not be measured and the alarm 714 ILLEGAL SEQUENCE DATA is raised. 1: The tool length is measured. When bit 3 is 0, no measurement is performed on models in which parameters are set as described below.  BA47 = 0 (turret type: ATC)  BA48 = &42 (axis of the head to be rotated: B)  K52 = 0 Note : For INTEGREX i with a workpiece hand, even if bit 3 is 0, the length of a milling tool can be measured.

   Range 0, 1 · Takes effect: Immediate

5. bit 4

6. bit 5

   Handling of measurement speed of 1 in/min or higher during laser tool length/diameter measurement with inch-specification machines

   0: Drop the fractional portion. 1: Do not drop the fractional portion. Examples of measurement speed during the execution of this measurement are given below. Example (1) 0.9 in/min 0.9 in/min 0.9 in/min Example (2) 1.1 in/min 1.0 in/min 1.1 in/min

   Range 0, 1 · Takes effect: Immediate

7. bit 7

   Planetary tapping in the MAZATROL rear XY mode

   Planetary tapping in the MAZATROL rear XY mode 0: Helical machining in the CCW direction (right-hand thread cutting) 1: Helical machining in the CW direction (left-hand thread cutting)

   Range 0, 1 · Takes effect: Immediate
