Detailed description
(1) Units of various data
These input setting units determine the parameter setting unit, program command unit and the
external interface unit for the PLC axis and handle pulse, etc. The following rules show how the
unit of each data changes when the input setting unit is changed. This table applies to the NC
axis and PLC axis.

(2) Program
command
The program command unit follows the above table.
If the data has a decimal point, the number of digits in the integer section will remain and the
number of digits in the decimal point section will increase as the input setting unit becomes
smaller.
When setting data with no decimal point, and which is a position command, the data will be
affected by the input setting increment and input command increment.
For the feed rate, as the input setting unit becomes smaller, the number of digits in the integer
section will remain the same, but the number of digits in the decimal point section will increase.
