*1 For the fan of the 7.5kW or less dedicated motor, the power supply is single phase.
*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 page 37).
*4 Use [Pr. 190 to Pr. 196 Output terminal function selection] to assign the function to any of terminal (refer to page 61).
*5 The encoder should be coupled on the same axis with the motor shaft without any mechanical looseness. 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 91).
*7 For the differential line driver, set the terminating resistor selection switch to ON position (initial status) to use (refer to page
86). Note that the terminating resistor switch should be set to OFF position when sharing the same encoder with other unit
(NC, etc.) and a terminating resistor is connected to other unit.
For the complementary, set the switch to OFF position.
*8 Refer to page 88 for terminal compatibility of the FR-JCBL, FR-V5CBL, FR-A7AP, and FR-A7AL.
*9 A separate power supply of 5V/12V/15V/24V is necessary according to the encoder power
specification.
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-A7AX is
necessary. Refer to page 424 for external stop position command.
*11 Assign OH (external thermal input) signal to the terminal CS.
([Pr. 186 = 7])
Connect a 2W1k resistor between the terminal PC and CS (OH).
Install the resistor pushing it against the bottom part of the terminal block so as to avoid a
contact with other cables.

Used to enter an orientation signal for orientation.
For the terminal used for X22 signal input, set 22 in any of [Pr. 178 to Pr. 189] to assign the function.
Common terminal for the orientation signal.
Switched low if the orientation has stopped within the in-position zone while the start and orientation
signals are input.
For the terminal used for the ORA signal output, assign the function by setting 27 (positive logic) or
127 (negative logic) in any of [Pr. 190 to Pr.196].
Switched low if the orientation has not stopped within the in-position zone while the start and
orientation signals are input.
For the terminal used for the ORM signal output, assign the function by setting 28 (positive logic) or
128 (negative logic) in any of [Pr.190 to Pr.196] .
Common terminal for the ORA and ORM open collector output terminals.
