Remote Output Selection (Rem Signal, Pr. 495, Pr. 496) - Mitsubishi Electric FR-D720-008 Instruction Manual

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.

The above parameters can be set when Pr. 160 Extended function display selection = "0". (Refer to page 160)
* 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 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 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, these are the settings at power OFF. (The settings are stored at power OFF.)
When Pr. 495 ="10, 11", these are the same as before an inverter reset is made.

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
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).
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 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, 11", signal before rest is saved even at
inverter reset.
