ORIENTATION CONTROL

 For the fan of the 7.5 kW or less dedicated motor, the power supply is single phase (200 V/50 Hz, 200 to 230 V/ 60 Hz).

 The pin number differs according to the encoder used.

 Use Pr. 178 to Pr. 189 (input terminal function selection) to assign the function to any of terminal.

Refer to the Instruction Manual (Detailed) for details of Pr. 178 to Pr. 189 (input terminal function selection).

 Use Pr. 190 to Pr. 196 (output terminal function selection) to assign the function to any of terminal.

Refer to the Instruction Manual (Detailed) for details of Pr. 190 to Pr. 196 (output terminal function selection).

 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 page 12.)

 For the differential line driver, set the terminating resistor selection switch to on position (initial status) to use. (Refer to page 10.)

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 page 16.

 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.

When performing encoder feedback control and vector control together, an encoder and power can be shared.

 When a stop position command is input from outside, a plug-in option FR-A8AX is necessary. Refer to the Instruction Manual (Detailed)

for details of external stop position command.

 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 Instruction Manual (Detailed) of the inverter.)
