<Description>
• When the first phase-Z signal is detected after this signal has become “1,” the bit data signal for phase-Z detection
becomes “1.”
In current value data area 2, the deviation amount data or the lower word of the current value counter at the
moment phase-Z was detected is output.
When this detect command becomes “0,” the bit data signal for phase-Z detection returns to “0.”
In addition, in current value data area 2, the upper word of the current value counter is output.

1) Not detected because the phase-Z detect command is “0.”
2) Not accepted because phase-Z has already been detected.
3) Deviation amount when phase-Z was detected.
4) The lower word of the current value counter when phase-Z was detected.
Precaution:
Deviation amount is signed data. In this module, the deviation amount is calculated using 32-bit signed data.
When the deviation amount exceeds 32,767 pulses, “-32,768” is output as the deviation amount when phase-Z was
detected.
(Because current value data area 2 is of one word length.)
