Description
Remote output data is cleared when
the power supply is turned OFF
Remote output data is retained when
the power supply is turned OFF
Remote output data is cleared when
the power supply is turned OFF
Remote output data is retained when
the power supply is turned OFF
Set values for the bits corresponding to each output terminal of the
inverter output terminal. (Refer to the diagram below.)
Set values for the bits corresponding to each output terminal of
options FR-A8AY and FR-A8AR. (Refer to the diagram below.)
• The output terminal can be turned ON/OFF with the Pr.496
and Pr.497 settings. ON/OFF control can be performed for
the remote output terminal via the PU connector, RS-485
terminals and communication option.
• To assign the Remote output (REM) signal to the terminal to
be used for remote output, set "96 (positive logic) or 196
(negative logic)" in any of Pr.190 to Pr.196 (Output
terminal function selection).
• Refer to the left figure, and set "1" in the terminal bit
(terminal with the REM signal assigned) of Pr.496 or Pr.497
to turn ON the output terminal (OFF when using negative
logic). Set "0" to turn OFF the output terminal (ON when
using negative logic).
• For example, when Pr.190 RUN terminal function
selection = "96" (positive logic) and "1" (H01) is set in
Pr.496, the terminal RUN turns ON.
• If the power supply is reset (including a power failure) while
Pr.495 = "0 (initial value) or 10", 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.
