Function assignment of external terminals and CC-Link communication virtual terminals
5.13.6 Remote output selection (REM signal, Pr. 495, Pr. 496)
You can utilize the ON/OFF of the inverter's output signals instead of the remote output terminal of the programmable
logic controller.

The above parameters can be set when Pr. 160 User group read selection = "0". (Refer to page 197)
∗ This parameter allows its setting to be changed during operation in any operation mode even if "0" (initial value) is set in Pr. 77 Parameter write selection.
<Remote output data>
Pr. 496
 The output terminal (Y0) can be turned ON/OFF
depending on the Pr. 496 setting. The remote output
selection can be controlled ON/OFF by CC-Link
communication.
 To assign the remote output (REM) signal to the terminal
Y0, set "96 (positive logic) or 196 (negative logic)" in
Pr.190 RX2 (terminal Y0) function selection.
 When you refer to the diagram on the left and set 1 to the
terminal bit (terminal Y0 where the REM signal has been
assigned) of Pr. 496, the terminal Y0 turns ON (OFF for
negative logic). By setting 0, the terminal Y0 turns OFF
(ON for negative logic).

Example: When "96 (positive logic)" is set in Pr. 190 RX2 (terminal Y0) function selection and "1" (H01) is set in Pr. 496, the
terminal Y0 turns ON.

Signal condition during a reset
∗ When Pr. 495 = "1," the signal condition saved in EEPROM (condition of the
last power OFF) is applied.
 When Pr. 495 = "0 (initial value), 10", performing a power ON
reset (including a power failure) clears the REM signal
output. (The ON/OFF status of the terminal Y0 is as set in
Pr. 190.) The Pr. 496 setting is also "0".
When Pr. 495 = "1, 11", the remote output data before power
OFF is stored into the EEPROM, so the signal output at
power recovery is the same as before power OFF. (See the
chart on the left) However, it is not stored when the inverter
is reset (reset request via CC-Link communication).
 When Pr. 495 = "10 or 11," the signal before the reset is held
even during an inverter reset.
REMARKS
 The output terminal where the REM signal is not assigned using any of Pr. 190 does not turn ON/OFF if 0/1 is set to the terminal
bit of Pr. 496. (It turns ON/OFF with the assigned function.)
