4-4. Changing the Settings
For analog output types, only make the settings in section 4-4-5, "Setting the Reference Point Output and
Reference Point Detection Direction." Always use the settings in Table 4-1 for analog output types, except
for the settings in section 4-4-5, "Setting the Reference Point Output and Reference Point Detection Direction."
4-4-1. Changing the Direction
MODE switch 3 (Direction switch) is used to change the positional relationship of the A/B signal with
respect to the scale movement direction.

4-4-2. Changing the Resolution
MODE switch 6 (resolution setting switch) is used to change the resolution of the A/B signal output type.
In the case of output format F: ON = 0.1 µm
4-4-3. Setting the Reference Point Output Signal Width
The width of the reference point output signal can be changed by MODE switch 10 (reference point mode
switch).

The reference point signal is output in synchronization when both the
A and B signal are at the high level.
Reference point mode
The reference point signal is output in synchronization during the one
cycle of the A signal.
