 Switches on the FR-A8AP
• Use the encoder type selection switch (SW3) to select the differential line driver or the complementary.
It is initially set to the differential line driver. Switch its position according to the output circuit.
• Use the terminating resistor selection switches (SW1) to select ON/OFF of the internal terminating resistor.
Set the switches ON (initial status) when an encoder output type is differential line driver, and set 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 switches OFF when sharing an encoder with another unit (CNC (computerized numerical controller), etc.) having a
terminating resistor under the differential line driver setting.
