Mitsubishi Electronics FR-F740P ユーザーズマニュアル

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

0 to 4095

The above parameters can be set when Pr. 160 User group read selection = "0". (Refer to page 201)
* This parameter allows its setting to be changed during operation in any operation mode even if "0" (initial value) is set in Pr. 77 Parameter write selection.

<Remote output data>

*1 As desired

*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

⋅ 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) in 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 left 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).

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.

*

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 or 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.
