*1 For the fan of the 7.5kW or less dedicated motor, the power supply is single phase. (200V/50Hz, 200 to 250V/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 page 221.)
*4 Use Pr. 190 to Pr. 196 (output terminal function selection) to assign the function to any of terminal. (Refer to page 228.)
*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 41.)
*7 For the differential line driver, set the terminating resistor selection switch to on position (initial status) to use. (Refer to page 37.)
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-V5CBL and FR-A7AP, refer to page 38.
*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 213 for external stop position
command.)
*11 Assign OH (external thermal input) signal to the terminal CS. (Pr. 186 = "7")
Connect a 2WlkΩ 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.
<Setting>
If the orientation command signal (X22) is turned on during operation after the various parameters have been set, the
speed will decelerate to the "orientation switchover speed". After the "orientation stop distance" is calculated, the speed
will further decelerate, and the "orientation state" (servo lock) will be entered. The "orientation complete signal" (ORA)
will be output when the "orientation complete width" is entered.

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)Ein any of Pr. 190 to Pr. 196.
Common terminal for the ORA and ORM open collector output terminals.
