Function assignment of external terminal and control
4.10.8 Remote output selection (REM signal, Pr. 495, Pr. 496)
You can utilize the on/off of the inverter's output signals instead of the remote output terminal of the programmable logic
controller.

Refer to the following diagram.
The above parameters can be set when

= "0".
* The above parameters allow its setting to be changed during operation in any operation mode even if "0" (initial value) is set in

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).

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
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, Pr. 192
. ) The
Pr. 496
setting is 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 inverter is reset (terminal reset, reset
request through communication).
(See the chart on the left)
When
Pr. 495
= "10, 11", signal before rest is saved even at
inverter 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 or Pr. 497
. (It turns on/off with the assigned function.)
When the inverter is reset (terminal reset, reset request through communication),
Pr. 496
values turn to "0". When
Pr. 495
= "1,
11", however, they are the settings at power off. (The settings are stored at power off.)
When
Pr. 495
="10, 11", they are the same as before an inverter reset is made.
