(1) Connection example
*1
The pin number differs according to the encoder used.
*2
Use
Pr. 178 to Pr. 189 (input terminal function selection)
to assign the function to any of terminal.
(Refer to page 222.)
*3
Use
Pr. 190 to Pr. 196 (output terminal function selection)
to assign the function to any of terminal.
(Refer to page 230.)
*4
Connect the encoder so that there is no looseness between the motor and motor shaft. Speed ratio should be 1:1.
*5
Earth (Ground) the shielded cable of the encoder cable to the enclosure with a P clip, etc.
(Refer to page 36.)
*6
For the differential line driver, set the terminating resistor selection switch to on position (initial status) to use.
(Refer to page 32.)
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.
*7
For terminal compatibility of the FR-JCBL and FR-A7AP,
refer to page
33
.
*8
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.
*9
When a stop position command is input from outside, a plug-in option FR-A7AX is necessary. Refer to
page 214
for external stop position
command.)
<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.

Terminal Name
Application Explanation
X22
*1
Orientation command input
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.
SD
Contact input common
Common terminal for the orientation signal.
ORA
*2
Orientaiton complete signal
output
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
.
ORM
*2
Orientation fault signal output
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
.
SE
Open collector output common
Common terminal for the ORA and ORM open collector output terminals.
*1
For X22 signals, assign functions to any of terminal using
Pr. 178 to Pr. 189 (ouput terminal function selection)
.
(Refer to page 222)
*2
For ORA and ORM signals, assign functions to any of terminal using
Pr. 190 to Pr. 196 (ouput terminal function selection)
.
