18 Number of Digits
Below Decimal
Point (DECNUM) 0 to 5
(Default = 3) Sets the number of digits
below decimal point in com-
mands.
(Example)
With 3 digits below decimal
point
mm: 1 reference unit =
0.001 mm
deg: 1 reference unit =
0.001 deg
inch:1 reference unit =
0.001 inch Minimum reference unit
is determined by this
parameter as well as by
the Reference Unit Selec-
tion (see fixed servo
parameter no. 17.). They
do not affect the pulse
minimum unit.
