(M) Monitor display and monitor output signal
Parameters
5 - 242
Remote output data retention (REM signal, Pr. 495)
●
If the power supply is reset (including a power failure) while Pr. 495 = "0 (initial value) or 10", t the
REM signal output is cleared. (The terminal ON/OFF status is determined by the settings in Pr. 190
to Pr. 196.) "0" is also set in Pr. 496 and Pr. 497.
●
When Pr. 495 = "1 or 11", the remote output data is saved in EEPROM before the power supply is
turned OFF. This means that the signal output after power restoration is the same as before the
power supply was turned OFF. However, when Pr. 495 = "1", the data is not saved during an inverter
reset (terminal reset, reset request via communication).
●
When Pr. 495 = "10 or 11", the signal before the reset is saved even during an inverter reset.

NOTES
The output terminals that have not been assigned with a REM signal by Pr. 190 to Pr. 196 do not
turn ON/OFF even if "0 or 1" is set in the terminal bits of Pr. 496 and Pr. 497. (ON/OFF is performed
with the assigned functions.)
When Pr. 495 = "1 or 11" (remote output data retention at power OFF), take measures such as con-
necting R1/L11 with P/+, and S1/L21 with N/- so that the control power is retained. If the control
power is not retained, the output signal after turning ON the power is not guaranteed to work.
When connecting the high power factor converter FR-HC2 or the converter unit FR-CC2, assign the
instantaneous power failure detection (X11) signal to an input terminal to input the IPF signal
from the FR-HC2/FR-CC2 to the terminal for X11 signal.
