Set the unit for the reference that is input.
The minimum reference unit is determined by this parameter and, the Number of Decimal Places (fixed parameter 5). If
pulse is selected, the Electronic Gear Ratio (fixed parameters 8 and 9) will be disabled.

Set the number of places to the right of the decimal point in input references.
The minimum reference unit is determined by this parameter and the Command Unit (fixed parameter 4).
Example
If Command Unit = mm and Number of Digits Below the Decimal Place = 3
Then, a reference unit of 1 = 0.001 mm
The setting of this parameter is disabled if the Command Unit is set to pulse in fixed parameter 4.
