Phase Z Signal Output
1 phase-Z signal is output by 1 pulse per motor rotation. When the Encoder Dividing
Denominator (Pn503) ≠ 0, and if the pulse output resolution per rotation is not a multiple of 4,
phase-Z and phase-A outputs are not synchronized. The output will be made as an encoder
resolution, resulting in narrower width.

When the output source is the encoder
When Encoder Dividing Denominator (Pn503) = 0
This is set by Encoder Dividing Numerator (Pn011), and the output pulse is
the number of pulses set by Encoder Dividing Numerator (Pn011) as follows.
Encoder pulse
Number of pulse output per rotation = Encoder Dividing Numerator (Pn011)
× 4
When the output source is the external encoder
When Encoder Dividing Denominator (Pn503) = 0
The dividing ratio is 1:1.
External encoder pulse
When Encoder Dividing Denominator (Pn503) ≠ 0
The output pulse will be as follows based on Encoder Dividing Numerator
(Pn011) and Encoder Dividing Denominator (Pn503).
