Setting the Measurement Unit
G20 and G21 can be used to set the measurement unit used for movement, feed rate, and offset amounts.
G20 : Inch input
G21
: Millimeter input
Either G20 or G21 is set at the start of the program, before setting the coordinate system. G20 and G21 should not be changed during
the course of a program. If the unit is not set by programming, the setting made on the PNC-3200 is used.
The minimum units differ for inch input and millimeter input.
Real-number Entry and Integer Entry
Movement amount (length), feed rate, and time may be input using either real-number entry or integer entry.
Input of a number which contains a decimal point (for example “10.0” or “10.”) is called real-number entry, and input of a number
without a decimal point is called integer entry. A value such as “10.0” where the portion to the right of the decimal point is zero may be
abbreviated to “10.” with no change in value.
When real-number entry is used, the numerical value is interpreted as being in the measurement unit that has been set. When integer
entry is used, the numerical value is interpreted as being the minimum unit of the measurement unit that has been set. Some examples
of this are as follows.
* The measurement unit is set by G20 (inch input) or G21 (millimeter input).
* If the unit is not set by programming, the setting made on the PNC-3200 is used.
There are two types of methods for setting the speed of the spindle motor: setting as an rpm value, and setting as a numerical code. See
"Spindle Speed Function (S Function) for details.
