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.
Ö Input PULS CN1-7 Reference Pulse Input Position Control
Ö Input /PULS CN1-8 Reference Pulse Input Position Control
Ö Input SIGN CN1-11 Reference Code Input Position Control
Ö Input /SIGN CN1-12 Reference Code Input Position Control
The servomotor only rotates at an angle proportional to the input pulse.
