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. When
the IS–C increment system is selected, it is applied to all axes and the 1/10
increment system option is required. The setting of parameter ISC (No.
1004#4) is valid for all axes. When IS–C is selected, for example, the
setting units for all axes are IS–C.
