4.11.8 Remote output selection (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
logic controller.

The above parameters can be set when Pr. 160 User group read selection = "0". (Refer to page 188)
∗ This parameter allows its setting to be changed during operation in any operation mode even if "0" (initial value) is set in Pr. 77 Parameter write selection.

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.

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 or Pr. 497. (It turns ON/OFF with the assigned function.)

Refer to the following diagram.

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 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 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 and Pr. 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. (See the
chart on the left) However, it is not stored when the inverter
is
reset
(terminal
communication).
When Pr. 495 = "10 or 11," the signal before the reset is held
even during an inverter reset.
