Frequency
Select the differential phase input mode, the pulse + direction input mode, the
up/down pulse input mode, or the increment mode. These modes are explained
below.
Select one of the following as the input frequency range: 10 Hz to 500 Hz, 20 Hz
to 1 kHz, or 300 Hz to 20 kHz. For more information on input frequencies, refer to
the following diagrams.
Differential Phase Input Mode
In the differential phase input mode, the count is incremented or decremented
according to two differential phase signals (phase A and phase B) with a multi-
plication factor of 4.

Pulse + Direction Input Mode
In the pulse + direction input mode, pulse signals and direction signals are input,
and the count is incremented or decremented according to the direction signal
status.

Up/Down Pulse Input Mode
In the up/down pulse input mode, CW signals (up pulses) and CCW signals
(down pulses) are input, and the count is incremented or decremented accord-
ingly.
