*1 Single-phase power supply (200 V/50 Hz, 200 to 230 V/60 Hz) is used for the fan for a 7.5 kW or lower dedicated motor.
*2 The pin number differs according to the encoder used.
*3 Use Pr.178 to Pr.189 (Input terminal function selection) to assign the function to a terminal. (Refer to
*4 Use Pr.190 to Pr.196 (Output terminal function selection) to assign the function to a terminal. (Refer to
*5 Connect the encoder so that there is no looseness between the motor and motor shaft. Speed ratio must be 1:1.
*6 Connect the shield of the encoder cable to the enclosure using a tool such as a P-clip. (Refer to
*7 For the differential line driver, set the terminating resistor selection switch to the ON position (initial status) to use. (Refer to
Note that the terminating resistor switch should be set to the OFF position when sharing the same encoder with another unit (NC, etc.) or when
the terminating resistor is connected to another unit. For the complementary, set the switch to the OFF position.
*8 For terminal compatibility of the FR-JCBL, the FR-V5CBL, and the FR-A8AP, refer to
*9 A separate power supply of 5 V/12 V/15 V/24 V is necessary according to the encoder power specification. Make the voltage of the external power
supply 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 supply can be shared.
*10 When a stop position command is input from outside, a plug-in option FR-A8AX is required. Refer to
command.
*11 Connect the recommended 2W1kΩ resistor between terminals PC and OH. (Recommended product: MOS2C102J 2W1kΩ by KOA Corporation)
Insert the input line and the resistor to a 2-wire blade terminal, and connect the blade terminal to terminal OH. (For the recommended 2-wire blade
terminals, refer to page
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 do 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 terminal OH, assign the External thermal relay input (OH) signal to an input terminal. (Set "7" in any of Pr.178 to Pr.189.)
 Setting
• When the Orientation command (X22) signal is turned ON during operation after the parameters are set, the motor is
decelerated to the orientation switchover speed. Then, the inverter calculates the orientation stop distance, further
decelerates the motor and the motor enters the orientation state (servo lock). The Orientation complete (ORA) signal is
output when the motor is within the orientation complete width.
