Initializing time 1 to 2 s
Z-phase pulse At low speed: About 6 ms (Note 3)
width
At high speed: About 440 μs
Note 1. Depending on the servo motor being used, "Electronic gear" needs to be set.
2. The parameters need to be set due to output pulse settings.
3. This is the pulse width when the motor rotates at 10 r/min. The pulse width changes depending on rotational frequency.
