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
.)
For the differential line driver, set the terminating resistor selection switch to on position (initial status) to use. (Refer to
) Note that
the terminating resistor switch should be set to off position when sharing the same encoder with other unit (CNC, etc) and 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-A8AP, refer to
A separate power supply of 5 V/12 V/15 V/24 V is necessary according to the encoder power specification. When the encoder output is
the differential line driver type, only 5 V 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.
