Analog output types
Always use the settings in Table 4-1 except for the switches below.
The description of the switches below is identical to the A/B signal output types.
Analog output types do not have alarm output.
Also, the reference point output signal width cannot be changed.
MODE switch 4 (Default reference point detection direction setting switch)
MODE switch 7 (Reference point output selector switch)
MODE switch 9 (Reference point detection direction selector switch)
4-5. Changing the Settings
For analog output types, only make the settings in section 4-5-5, “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 4-5-5, “Setting the Reference Point Output and Reference Point Detection Direction.”
4-5-1. 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.
MODE switch 3 Moves to head cable side
OFF A signal is leading
ON B signal is leading

4-5-2. Changing the Resolution
MODE switch 6 (resolution setting switch) is used to change the resolution of the A/B signal output type.

4-5-3. 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).
MODE switch 10 Reference point output signal width
(reference point mode switch)
ON 1/4 reference point mode
The reference point signal is output in synchronization when both the
A and B signal are at the high level.
OFF Reference point mode
The reference point signal is output in synchronization during the one
cycle of the A signal.
