■Load sensor connection
Set the excitation voltage, and turn off the power before sensor connection as shown below.
- 4-wire sensor - 6-wire sensor
For connection of a 6-wire strain gauge type
sensor, short-circuit +EXC and +S,
and –EXC and –S.
■Displacement sensor connection (standard)
- Input equivalent circuit
An open collector output type sensor (Incremental type) can be connected.
CAUTION
The excitation voltage of the F381A is 2.5V/10V. If the maximum excitation voltage of
the sensor is under 2.5V/10V, heating or damage may result.

* Z-Phase is not usually wired. It is wired when the indicated value is adjusted to zero at the
original point of the rotary encoder.
* Please wire for the power supply of the sensor separately.
