1.2.9 The pulse width of the encoder Z-Phase pulse
Note that the pulse width and start-up timing of the encoder Z-phase pulse signal (OP) output from the servo
amplifier are different between the MR-J2S / MR-J2M series and the MR-J4 series.
<Precautions>
* Always reset the home position upon replacement.

Note 1. This is the pulse width when the servo motor rotates at 10 r/min. The time for the pulse width varies depending on the
number of the servo motor revolutions.
2. Pulse width = 128 × (60/(servo motor speed × 131072) × 10
