The increment system consists of the least input increment (for input ) and
least command increment (for output). The least input increment is the
least increment for programming the travel distance. The least command
increment is the least increment for moving the tool on the machine. Both
increments are represented in mm, inches, or degrees.
The increment system is classified into IS–B and IS–C (Tables 2.3 (a) and
2.3 (b)). Select IS–B or IS–C using bit 1 (ISC) of parameter 1004. The
setting of bit 1 (ISC) of parameter No.1004 applies to all axes. When
IS–C is selected, for example, the increment system for all axes is set to
IS–C.
