Switches of the FR-A8AP
Encoder type selection switch (SW3)
Selects either the differential line driver or complementary setting.
It is initially set to the differential line driver. Switch its position according to the
output circuit.
Terminating resistor selection switch (SW1)
Selects 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
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.
Prepare an encoder's power supply (5 V/12 V/15 V/24 V) according to the encoder's output voltage. When the encoder output
is the differential line driver type, only 5 V can be input.
The SW2 switch is for manufacturer setting. Do not change the setting.
