1.4.24 Remote output function (REM)
(common)
You can utilize the ON/OFF of the inverter's output signals
instead of the remote output terminal of the programmable
controller.
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 terminal
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 following 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).
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, Pr. 497
]. (It turns ON/
OFF with the assigned function.)
For example when [
Pr. 190 RUN terminal function selection
=
96] (positive logic) and set 1 (H01) in [
Pr. 496
], the terminal
RUN turns ON.
When [
Pr. 495
= 0, 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. 196
]. ) The [
Pr. 496, 497
] 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.
However, it is not stored into EEPROM when the inverter is
reset (terminal reset, reset request through
communication). (Refer to the following diagram)
When [
Pr. 495
= 10, 11], signal before reset is saved even
at inverter reset.

When [
Pr. 495
= 1, 11] (remote output data retention even
at powering OFF), take such corrective action as
connection of R1/L11, S1/L21 and P/
+
, N/
-
, to hold the
control power supply. If you do not take such a step, the
output signals provided after power-ON are not
guaranteed.
