Caution : If the phase Z is used to specify the position scale of the Motor, be sure to
use the rising edge of the signal.
 The phase Z is made to have precise position repeatability on its rising edge
regardless of the Motor rotational direction.
 Use of the falling edge of the signal to detect the base position won’t maintain the
position repeatability because of the effect caused by difference in pulse width when
reversing the rotational direction.

Caution : The output signals of the phases A, B and Z are not synchronized each
other.
