   Fixed value (1)

2. bit 1

   Correction timing of the touch sensor tool length during EIA/ISO programmed or MDI operation (for machining center specifications only)

   Select the timing in which the tool length of the touch sensor is to be made valid during EIA/ISO programmed or MDI operation when the following conditions are satisfied:  F93 bit 3 = 1 (using MAZATROL tool length)  F94 bit 7 = 0 (using tool offsets) 0: When a move command is executed for any controlled axis (X, Y, Z, or rotational axis) 1: When a move command is executed for the Z-axis

   Range 0, 1 · Takes effect: Immediate

3. bit 2

   Operation at an EIA subprogram call from a MAZATROL program

   Select whether the zero point return is to be executed at an EIA subprogram call from a MAZATROL program. 0: Executed 1: Not executed

   Range 0, 1 · Takes effect: Immediate

4. bit 3

   Judgment method for tool change command output during MAZATROL programmed operation

   Select whether the index angle of the spindle is to be checked during MAZATROL programmed operation when a judgment on whether a tool change is necessary. 0: No check (No tool change command is output when the tool is the same in tool name, nominal size, and suffix.) 1: Check (No tool change command is output when the tool is the same in tool name, nominal size, suffix, and spindle index angle.)

   Range 0, 1 · Takes effect: Immediate

5. bit 4

   Tool change command output at the start of MAZATROL programmed operation

   Select whether the tool change command is to be output during MAZATROL programmed operation when the machining unit is executed for the first time. 0: Output of the tool change command except for the same tool 1: Unconditional output of the tool change command

   Range 0, 1 · Takes effect: Immediate

6. bit 7

   Reference value for judging tool breakage during laser tool measurement

   Select a method of judging tool breakage during laser tool measurement. 0: Judging from the setting of parameter L6 For details, refer to the explanation of parameter L6. 1: Judging from the tolerance specified in the program If (“registered tool length data” – “tool length data that has been measured during the detecting operation”) > “tolerance set in the program”, then the tool is judged to be broken.

   Range 0, 1 · Takes effect: Immediate
