Note: The noise margin of the input signal will decrease if the reference pulse is provided by an
open-collector output. Set parameter Pn200.3 to 1 if the position drifts due to noise.
Selecting a Reference Pulse Form
Use the following parameters to select the reference pulse form used.
The servomotor only rotates at an angle proportional to the input pulse.
Set reference pulse form input to the servo amplifier from the host controller.
