INSTALLATION AND WIRING

2.3 Encoder specification / terminating resistor switch setting

Encoder specification selection switch (SW3)

Select either differential line driver or complementary.
It is initially set to the differential line driver. Switch its position according 
to output circuit.

Terminating resistor selection switch (SW1)

Select "ON"/"OFF" of the internal terminating resistor. Set the switch to 
"ON" (initial status) when an encoder output type is differential line driver 
and set to "OFF" when complementary.
ON : with internal terminating resistor (initial setting status)
OFF : without internal terminating resistor

NOTE

 • Set all switches to the same setting ("ON"/ "OFF").
 • If the encoder output type is differential line driver, set the 

terminating resistor switch to the "OFF" position when 
sharing the same encoder with other unit (CNC 
(computerized numerical controller), etc) or a terminating 
resistor is connected to other unit.
