 If encoder dividing denominator ≠ 0, division is performed at the rate according to the formula
below.

Therefore, the formula will be as follows when the host side counts pulses through processing with
quadruple multiplier.

The pulse output resolution per rotation will never exceed the encoder resolution. (If the above
settings are used, the pulse output resolution per rotation will be equal to the encoder resolution.)
1 phase-Z signal is output for each rotation of the motor.
If the pulse output resolution per rotation from the above equation is a multiple of 4, phases Z and
A are output in synchronization. In all other cases, the output width of phase Z will be output as
the encoder resolution, resulting to be narrower than phase A. Accordingly, phases A and Z will
not be synchronized.
The output source is the encoder and
the pulse dividing ratio is a multiple of 4.
