The pin number differs according to the encoder used.

Connect the encoder so that there is no looseness between the motor and motor shaft. Speed ratio should be 1:1.

Earth (Ground) the shielded cable of the encoder cable to the enclosure with a P clip, etc. (Refer to page 9.)

For the differential line driver, set the terminating resistor selection switch to on position (initial status) to use.

(Refer to page 7) Note that the terminating resistor switch should be set to off position when sharing the same

encoder with other unit (NC, etc) or a terminating resistor is connected to other unit.

For the complementary, set the switch to off position.

For terminal compatibility of the FR-JCBL, FR-V7CBL and FR-A7AP, refer to page 14.

A separate power supply of 5V/12V/15V/24V is necessary according to the encoder power specification.When the

encoder output is the differential line driver type, only 5V can be input.

Make the voltage of the external power supply the same as the encoder output voltage, and connect the external

power supply between PG and SD.

To perform orientation control together, an encoder and power supply can be shared.
