*1 For the fan of the 7.5kW or less dedicated motor, the power supply is single phase (200V/50Hz, 200 to 230V/
60Hz).
*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 any of terminal.
Refer to the inverter manual for details of Pr. 178 to Pr. 189 (input terminal function selection).
*4 Use Pr. 190 to Pr. 196 (output terminal function selection) to assign the function to any of terminal.
Refer to the inverter manual for details of Pr. 190 to Pr. 196 (output terminal function selection).
*5 Connect the encoder so that there is no looseness between the motor and motor shaft. Speed ratio should be 1:1.
*6 Earth (Ground) the shielded cable of the encoder cable to the enclosure with a P clip, etc. (Refer to page 9.)
*7 For the differential line driver, set the terminating resistor selection switch to on position (initial status) to use.
(Refer to page 7.)
Note that the terminating resistor switch should be set to off position when sharing the same encoder with other
unit (NC, etc.) or a terminating resistor is connected to other unit.
For the complementary, set the switch to off position.
*8 For terminal compatibility of the FR-JCBL, FR-V7CBL and FR-A7AP, refer to page 14.
*9 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 encoder feedback control and vector control together, an encoder and power can be shared.
*10 When a stop position command is input from outside, a plug-in option FR-
A7AX is necessary. Refer to the inverter manual for details of external
stop position command.
*11 Assign OH (external thermal input) signal to the terminal CS. (Set "7" in
Pr. 186 )
Connect a 2W1kΩ resistor between the terminal PC and CS.
Install the resistor pushing against the bottom part of the terminal block so
as to avoid a contact with other cables.
