(Example of setting) For detection in 1 µm units, specify as
follows:
Ball screw lead
Number of necessary
position pulses
F&FG
10 (mm/rev) 10000 (pulses/rev) 1/100
20 20000 2/100 or 1/50
30 30000 3/100
(Example of setting)
If the machine is set to detection in 1,000 degree units with
a gear reduction ratio of 100:1 for the rotation axis, the table
rotates by 360/100 degrees each time the motor makes one
turn. 1000 position pulses are necessary for the table to rotate
through one degree. The number of position pulses necessary
for the motor to make one turn is:
360/100 _ 1000 = 3600
3600
=
F.FG numerator
F.FG denominator 1000000
=

10000
Number of position pulses necessary for
the motor to make one turn
Setting for use of a separate detector (full–closed)
=
F.FG numerator (32767)
F.FG denominator (32767)
(as irreducible fraction)
Number of position pulses from the separate
detector when the motor makes one turn
NOTE2
DMR can also be used with the separate position detector,
provided that F.FG = 0.
