Function assignment of external terminal and control
4.12.8 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 or by communication from the communication
option.
 Set "96 (positive logic) or 196 (negative logic)" to any of Pr.190
to 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).

Example: When "96 (positive logic)" is set in Pr.190 RUN terminal function selection and "1" (H01) is set in Pr.496 , the
terminal RUN turns ON.
ON/OFF example for positive logic
Signal condition during a reset
 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 to Pr.192 . ) The Pr.496 settings are 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 drive unit is reset (terminal reset, reset request
through communication).
 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 any of Pr.190 to 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.)
