For the phase-Z signal, one pulse will be output per motor rotation. When Encoder Dividing
Denominator (Pn503) is not 0, the phase-Z signal will not be output in sync with the phase-A signal
unless the resolution of pulse output per rotation is a multiple of 4. In this case, the phase-Z signal will
be output at the encoder resolution and its width may be narrower.

Description
1 to 262,144 0 [Output source: Encoder]
When Encoder Dividing Denominator (Pn503) is 0:
The number of output pulses is calculated based on Encoder Dividing
Numerator (Pn011) as follows.
Number of output pulses per rotation = Encoder Dividing Numerator (Pn011) x 4
