Earth (ground) the shield of the encoder cable to the enclosure using a tool such as a P-clip. (Refer
to page 2-71.)

For the differential line driver, set the terminating resistor selection switch to the ON position (initial
status) to use. (Refer to page 2-63.)
Note that the terminating resistor switch should be set to the OFF position when sharing the same
encoder with another unit (NC, etc.) or when the terminating resistor is connected to another unit.
For the complementary, set the switch to the OFF position.

For terminal compatibility between the FR-A8TP and the FR-JCBL/FR-V7CBL, refer to the Instruction
Manual of the FR-A8TP.

A separate power supply of 5 V/12 V/15 V is necessary according to the encoder power specifica-
tion. When the encoder output is the differential line driver type, only 5 V can be input. If using the
24 V power supply of the FR-A8TP, 24 V power can be supplied from terminal PG24. Make the
voltage of the external power supply same as the encoder output voltage, and connect the
external power supply between PG and SD.
The encoder and the power supply can be shared under orientation control, encoder feedback
control, or vector control.

When a stop position command is input from outside, a plug-in option FR-A8AX is required. Refer
to page 5-508 for the external stop position command.

To enable terminal OH, set Pr. 876 "Thermal protector input" = "1 (initial value)".
