4.10.8 Remote output function (REM signal, Pr. 495 to Pr. 497)

You can utilize the on/off of the inverter's output signals instead of the remote output terminal of the
programmable controller.

Example)When "96" (positive logic) is set to Pr. 190 RUN terminal function selection and "1" (H01) is set to Pr. 496,
the terminal RUN turns on.

REMARKS
The output terminal where the REM signal is not assigned using any of Pr. 190 to Pr. 196 does not turn on/off if 0/1 is set to the
terminal bit of Pr. 496 or Pr. 497. (It turns on/off with the assigned function.)
When the inverter is reset (terminal reset, reset request through communication), Pr. 496 and Pr. 497 values turn to "0". When Pr.
495 = "1, 11", however, they are the settings at power supply-off. (The settings are stored at power supply-off.) When Pr. 495 =
"10, 11", they are the same as before an inverter reset is made.
CAUTION
When Pr. 495="1, 11"(remote output data retention at power OFF), connect R1/11 with P/+, and S1/L21 with N/- so that the
control power is retained. If you do not take such a step, the output signals provided after power-on are not guaranteed.

When Pr. 495 = "0 (initial value), 10", performing a power
supply 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. 196.) The Pr. 496 and Pr. 497 settings are also "0".

When Pr. 495 = "1, 11", the remote output data before power

However, it is not stored when the inverter is reset (terminal
reset, reset request through communication).

Refer to the following diagram.
The output terminal can be turned on/off depending on
the Pr. 496 or Pr. 497 setting. The remote output
selection can be controlled on/off by computer link
communication from the PU connector or RS-485 port
or by communication from the communication option.
Set "96" (positive logic) or "196" (negative logic) in any
of Pr. 190 to Pr. 196 (output terminal function selection),
and assign the remote output (REM) signal to the
terminal used for remote output,
When you refer to the left diagram and set 1 to the
terminal bit (terminal where the REM signal has been
assigned) of Pr. 496 or Pr. 497, the output terminal turns
on (off for negative logic). By setting 0, the output
terminal turns off (on for negative logic).
