Remote output function (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
Pr.343
page 173
programmable logic controller.

496 * Remote output data 1
497 * Remote output data 2
The above parameters can be set when Pr. 160 User group read selection = "0". (Refer to page 140)
* 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.

*2 Y0 to Y6 are available only when the extension output option (FR-
A7AY) is fitted
*3 RA1 to RA3 are available only when the relay output option (FR-
A7AR) is fitted
Example)When "96" (positive logic) is set to Pr. 190 RUN terminal function selection and "1" (H01) is set to 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. 196 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 and Pr. 497 values turn to "0".
When Pr. 495 = "1", however, they are the settings at power supply-off. (The settings are stored at power supply-off.)
CAUTION
⋅ When Pr. 495 = "1", take such a step as to connect R1/L11, S1/L21 and P/+, N/- to ensure that control power will be retained
to some degree. If you do not take such a step, the output signals provided after power-on are not guaranteed.

depending on the Pr. 496 or Pr. 497 setting. The

remote output selection can be controlled on/off by
computer link
connector or RS-485 port or by communication
from the communication option.
⋅ Set "96" (positive logic) or "196" (negative logic) to
any of Pr. 190 to Pr. 196 (output terminal function
selection), and assign the remote output (REM)
b0
signal to the terminal used for remote output,
⋅ When you refer to the above diagram 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), performing a power
supply reset (including a power failure) clears the
REM signal output. (The ON/OFF states of the
terminals are as set in Pr. 190 to Pr. 196.) The Pr. 496
and Pr. 497 settings are also "0".
Inverter
reset time
When Pr. 495 = "1", the remote output data before
(about 1s)
power supply-off is stored into the EEPROM, so the
signal output at power recovery is the same as
before power supply-off. However, it is not stored
when the inverter is reset (terminal reset, reset
request through communication).
