*1
The pin number differs according to the encoder used.
Speed control and torque control are properly performed even without connecting Z-phase.
*2
The encoder should be coupled on the same axis with the motor shaft without any mechanical looseness.
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 12)
*4
For the differential line driver, set the terminating resistor selection switch to ON position. (Refer to page 10)
Note that the terminating resistor switch should be set to OFF position (initial status) when sharing the same encoder with other
unit (CNC, etc) and a terminating resistor is connected to other unit.
*5
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.
When performing orientation control together, an encoder and power supply can be shared.

Refer to page 17 for terminal compatibility of the FR-JCBL, FR-V7CBL and FR-A7AL.
