Note
The following table shows the signal logic for an open-collector output.
When Tr1 is ON
Equivalent to high-level input
When Tr1 is OFF
Equivalent to low-level input
This circuit uses the 12-V power supply built into the Servopack. Input is not insulated.

The noise margin of the input signal will decrease if the reference pulse is given using an open-collector output.
Set user constant Pn200.3 to 1 if the position drifts due to noise.
