Input Connection Examples
Each input is provided with both an NO (normally open) input and an NC
(normally closed) input that can be used according to specifications.
Leave unused NO inputs open and connect unused NC inputs to the power
supply.

NC contact
Select either NO or NC
inputs via the back-panel
DIP switch.
•
All inputs have independent grounds (commons) and are bi-directional.
Connect switches of at least 12-mA capacity.
•
Use a non-contact sensor (such as a proximity sensor) for the origin input
to reduce wear and deterioration.
The Position Control Unit has two pairs of origin input pins: A11 and B11, and
A8 and B8. Pins A11 and B11 are used with the open-collector output of a
sensor, while pins A8 and B8 are used to connect the line driver output of a
Z-phase encoder.
