Remote Output Selection (Rem Signal, Pr. 495, Pr. 496) - Mitsubishi Electric FR-D720-0.1K Instruction Manual

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.

The above parameters can be set when Pr. 160 Extended function display selection = "0". (Refer to page 163)
∗ 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 Pr.190, Pr.192 or Pr.197 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.
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,
Pr.192 or Pr.197 (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).
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, Pr.197 ) The Pr. 496 setting becomes 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 or 11," the signal before the reset is held
even during an inverter reset.
