ENCODER FEEDBACK CONTROL

*1 The pin number differs according to the encoder used.
*2 Connect the encoder so that there is no looseness between the motor and motor shaft. Speed ratio should be 1:1.
*3 Earth (Ground) the shielded cable of the encoder cable to the enclosure with a P clip, etc. (Refer to page 9.)
*4 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.
*5 For terminal compatibility of the FR-JCBL, FR-V5CBL and FR-A7AP, refer to page 14.
*6 A separate power supply of 5V is necessary according to the encoder power specification.
To perform orientation control together, an encoder and power supply can be shared.
