Phase Decoder
It converts signal of phase A, B output from Trigger
Selector to Up/Down signal.

0 ： FourPulse
1 ： HighResolution
GV EncoderMode
FourPulse
HighResolution
In case of set encoder mode to Four Pulse, perform Count
up/down when its state is changed to Phase A=L or Phase
B=L.
In case of set encoder mode to High Resolution, when it
detects edge of Phase A, Phase B is performs count
up/down according to signal level.
In this case
, encoder’s resolution is four folded(frequency
multiplier).
NOTE
Later sequence is proceeded synchronized with the
sampling clock of 6.25MHz generated internally. In order
to synchronize the exposure timing to the encoder
position, it is required to set encoder’s frequency less
than 200KHz.
4-15-4 Divider
Divide the counter output, and rounded down to an integer
is going to be output as next output mode data.

Output Mode
In this mode, it generates trigger pulses according to
Settings of Encoder Output Mode and outcome of dividing,
and outputs pulses to Trigger signal grid.
OFF
Trigger pulse is not output, but counting is
performed continuously.
Position Up
In case calculation outcome is greater
than the value stored in the camera, it
outputs trigger pulse. Absolute position is
assured when counting down.
Position Down
In case calculation outcome is lower than
the value stored in the camera, it outputs
trigger pulse. Absolute position is assured
when counting Up.
Direction Up
In case calculation outcome is greater
than the value stored in the camera, it
outputs trigger pulse. Absolute position is
not assured, and every time of up count it
outputs trigger pulse.
Direction Down
In case calculation outcome is lower than
the value stored in the camera, it outputs
trigger pulse. Absolute position is not
assured, and every time of down count it
outputs trigger pulse.
Motion
In case calculation outcome is different to
the value stored in the camera, it outputs
trigger pulse.
Everytime of Count up and down it outputs
trigger pulse.
