You can utilize the ON/OFF of the inverter's output signals instead of the remote output terminal of the
programmable logic controller.

Y0 to Y6 are available only when the extension output option (FR-A7AY)

is fitted

fitted

⋅ The output terminal can be turned ON/OFF depending

on the Pr. 496 or Pr. 497 setting. The remote output
selection can be controlled ON/OFF by computer link
communication from the PU 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) 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 or Pr. 497, the output terminal
turns ON (OFF for negative logic). By setting 0, the
output terminal turns OFF (ON for negative logic).

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.

ON/OFF example for positive logic

Signal condition during a reset

*

When  Pr. 495 = "1," the signal condition saved in EEPROM
(condition of the last power OFF) is applied. 

⋅ When  Pr. 495  = "0 (initial value), 10", performing a power

supply reset (including a power failure) clears the REM signal
output. (The ON/OFF status of the terminals are as set in Pr.
190 to Pr. 196.) The Pr. 496 and Pr. 497 settings are also "0".
When Pr. 495 = "1, 11", the remote output data before 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). 
(See the chart on the left)

⋅ When  Pr. 495 = "10, 11", the signal before the reset is held

even during an inverter reset.

⋅ 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 Pr. 495 = "1, 11" (remote output data retention at power OFF), connect R1/11 with P/+, and S1/L21 with N/- so that the

control power is retained. If you do not take such a step, the output signals provided after power-ON are not guaranteed.
