
The pin number differs according to the encoder used.
Speed, control, torque control, and position control by pulse train input are available with or without the Z-phase being connected.

Connect the encoder so that there is no looseness between the motor and motor shaft. Speed ratio must be 1:1.

Earth (ground) the shield of the encoder cable to the enclosure using a tool such as a P-clip. (Refer to

For the complementary, set the terminating resistor selection switch to OFF position. (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 across PG and
SD.

For terminal compatibility of the FR-JCBL, FR-V7CBL, and FR-A8AP, refer to

For the fan of the 7.5 kW or lower dedicated motor, the power supply is single phase. (200 V/50 Hz, 200 to 230 V/60 Hz)

Connect the recommended 2W1k resistor between the terminal PC and OH. (Recommended product: MOS2C102J 2W1k by KOA
Corporation)
Insert the input line and the resistor to a 2-wire blade terminal, and connect the blade terminal to the terminal OH. (For the recommended 2-wire
blade terminals, refer to
Insulate the lead wire of the resistor, for example by applying a contraction tube, and shape the wires so that the resistor and its lead wire will not
touch other cables. Caulk the lead wire securely together with the thermal protector input line using a 2-wire blade terminal. (Do not subject the
lead wire's bottom area to an excessive pressure.)
To use a terminal as the terminal OH, assign the OH (external thermal O/L relay input) signal to an input terminal. (Set "7" in any of Pr.178 to
Pr.189. For details, refer to the FR-A800 Instruction Manual (Detailed).)

Assign the function using Pr.178 to Pr.184, Pr.187 to Pr.189 (input terminal function selection).
 When position control is selected, terminal JOG function is invalid and simple position pulse train input terminal becomes valid.
 Assign the function using Pr.190 to Pr.194 (output terminal function selection).
