CAUTION

The pulse output part of this product outputs the voltage by

2.5V or more at the High level output, and outputs the

voltage of 0.5V or less at the Low level output. When

connecting with the photo-coupler input or the TTL level input,

please connect it after confirming the specification in the

pulse input part of the driver unit operates by the

above-mentioned voltage.

To prevent the circuit from malfunctioning due to noise, wire

it as far away from other signal lines and noise sources as

possible.

In addition, please insert a current-limiting resistor according

to the allowable current and drive current of the connected

input circuit.

To prevent the circuit from malfunctioning due to noise, wire

it as far away from other signal lines and noise sources as

possible.

Control signal/general-purpose signal output circuit

(OUT1 - OUT2, ERC, CP1, CP2 / OUT3)

Output circuit of this product for each output signal is illustrated

below.

The signal output is an open-collector output.

Therefore, a ground wire must be connected for driving.

Encoder input circuit

Encoder input circuit on this product is illustrated below. The

signal input is a differential input capable of connecting a line

driver output, TTL level output and open-collector output.

CAUTION

Please use the twisted-pair cable that does the shield

processing as a noise measures when connecting it with the

differential output.

Restrict the use of cables to 10m for the line driver output.

To prevent the circuit from malfunctioning due to noise, wire

it as far away from other signal lines and noise sources as

possible.
