Switches

(1) Encoder specification selection switch (SW1)
Select either differential line driver or complementary
It is initially set to the differential line driver. Switch its position
according to output circuit.
(2) Terminating resistor selection switch (SW2)
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 complimentary.
ON : with internal terminating resistor (initial setting status)
OFF : without internal terminating resistor
REMARKS
· Set all swithces 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 (NC (numerical controller), etc) or a
terminating resistor is connected to other unit.
CAUTION
SW3 is for manufacturer setting. Do not change from initially-set status (1, 2:OFF).
