PARAMETERS
4.10.8 Remote output selection (REM signal, Pr. 495, Pr. 496)
You can utilize the ON/OFF of the drive unit's output signals instead of the remote output terminal of the programmable
logic controller.

<Remote output data>
Pr. 496
The output terminal can be turned ON/OFF depending on
the Pr. 496 setting. The remote output selection can be
controlled ON/OFF by computer link communication from
the PU connector.
Set "96 (positive logic) or 196 (negative logic)" to Pr. 190
or Pr. 192 (output terminal function selection), and assign the
remote output (REM) signal to the terminal used for
remote output.
When you refer to the diagram on the left and set 1 to the
terminal bit (terminal where the REM signal has been
assigned) of Pr. 496, the output terminal turns ON (OFF
for negative logic). By setting 0, the output terminal turns
OFF (ON for negative logic).

terminal RUN turns ON.
ON/OFF example for positive logic
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 terminals are as set in Pr.
190 or Pr. 192) The Pr. 496 setting becomes 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. However,
it is not stored when the drive unit is reset (terminal reset,
reset request through communication).
(See the chart on the left.)
When Pr. 495 = "10 or 11," the signal before the reset is held
even during a drive unit reset.
REMARKS
The output terminal where the REM signal is not assigned using Pr. 190 or Pr. 192 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.)
