*1 The pin number differs according to the encoder used.
Speed and torque controls are available with or without the Z-phase being connected.
*2 Connect the encoder so that there is no looseness between the motor and motor shaft. Speed ratio must be 1:1.
*3 Earth (ground) the shield of the encoder cable to the enclosure using a tool such as a P-clip. (Refer to
*4 For the complementary, set the terminating resistor selection switches in the OFF position. (Refer to
*5 A separate external power supply 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 terminals
PG and SD.
*6 For terminal compatibility of the FR-JCBL, FR-V7CBL, and FR-A8AP, refer to .
*7 A single-phase power supply (200 V/50 Hz, 200 to 230 V/60 Hz) is used for the fan for the dedicated motor.
