Connecting Output Signals

Pulse output circuit (CW, CCW)

The pulse output circuit on this product, which is in the form of a differential line driver (AM26LS31

equivalent) as shown in the following figure, can be connected with differential input, opto-coupler, and

TTL level input.

CAUTION

- Please use the twisted-pair cable that does the shield processing as a noise measures when

connecting it with the differential input.
