Connection of motor with encoder (vector control)
(3) Switches of the FR-A7AP
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.
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 complementary.
ON : with internal terminating resistor (initial status)
OFF: without internal terminating resistor

Encoder specification
REMARKS
· 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 (NC
(numerical controller), etc) or a terminating resistor is connected to other unit.
