Decimal Point Input

In the G-code program input information which defines the path, distance, and speed of the tool, a decimal point that
commands the zero point in [mm] units can be input. For commands that do not use a decimal point, the minimum digit is the
minimum input command unit.
• Decimal point command is valid for distance, angle, time and speed in the G-code program.
• For command value data without decimal points, a movement command of 1 is a movement amount of
0.0001[mm](0.1[m]).
• For speed command data without decimal points, a speed command of 1 is a speed of 1.00[mm/min].
• For time command data without decimal points, a time command of 1 is a time of 0.001[s].
• The valid command value range for decimal point commands is shown below. Do not execute commands with G-code
programs that exceed the valid command value range.

Decimal point command list
The list for decimal point commands is shown below. A minor error (error code: 1FC3H (details code: 031AH)) occurs for
decimal point commands for addresses where decimal point command are invalid.
