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.

496 * Remote output data 1
497 * Remote output data 2
The above parameters can be set when Pr. 160 User group read selection = "0". (Refer to page 185)
* The above parameters allow its setting to be changed during operation in any operation mode even if "0" (initial value) is set in Pr. 77 Parameter write

*2 Y0 to Y6 are available only when the extension output option (FR-A7AY) is fitted
*3 RA1 to RA3 are available only when the relay output option (FR-A7AR) is fitted
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.)
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.

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).
 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 supply-OFF is stored into the EEPROM, so the
signal output at power recovery is the same as before
power supply-OFF. However, it is not stored when the
inverter is reset (terminal reset, reset request through
communication).
(See the chart on the left)
 When Pr. 495 = "10, 11", the signal during reset is held even
an inverter reset is made.
