3-2-1. Setting resolution
Th
e resolution denotes the diff erence in phase between the A and
B phase edges.
Th
e MJ100/110 can split scale signals from the detection head into
40 to 1000 divisions. Th
e default setting is 500 divisions (PL25:
10 μm; PL60: 4 μm). To change the resolution, set MODE switches
6 through 9 as given in Table 1.

Table 1
3-2-2. Setting the 1/2 division function
By using the 1/2 division function, it is possible to halve the
number of divisions (double the resolution) given in Table 1.
Th
e 1/2 division function setting is made using MODE switch 10.
MODE Switch 10
1/2 division function
ON
Do not halve the number of divisions
OFF
Halve the number of divisions
Th
e default setting is ON (do not halve the number of divisions).
Example: Resolution when the number of divisions is 100 at PL25
MODE Switch 10
Number of Divisions/Resolution
ON
100/50 µm
OFF
50/100 µm
Example: Resolution when the number of divisions is 500 at PL25
MODE Switch 10
Number of Divisions/Resolution
ON
500/10 µm
OFF
250/20 µm
Note
Th
e 1/2 division function (MODE switch 10) is not related to
the reference point synchronized with the A/B phase. For more
information, see the section “3-3. Using the reference point.”
