 Terminating resistor selection switch (SW1)
Selects "ON"/"OFF" of the internal terminating resistor.
Set the switch to "OFF (initial status)" when an encoder output type is complementary and set to "ON" when differential line
driver.
ON: with internal terminating resistor
OFF: without internal terminating resistor (initial status)
NOTE
• Set all switches to the same setting ("ON"/"OFF").
• Set the switch "OFF" when sharing an encoder with another unit (NC (computerized numerical controller), etc.) having a
terminating resistor under the differential line driver setting.
