Function assignment of external terminal and control
4.11.8 Remote output selection (REM signal, Pr. 495, Pr. 496)
You can utilize the ON/OFF of the drive unit's output signals instead of the remote output terminal of the programmable
logic controller.

The above parameters can be set when Pr. 160 Extended function display selection = "0". (Refer to page 161.)

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 .

Pr. 496
 The output terminal can be turned ON/OFF depending on
the
Pr. 496 setting. The remote output selection can be
controlled ON/OFF by computer link communication from
the PU connector.
 Set "96 (positive logic) or 196 (negative logic)" to Pr. 190
or Pr. 192 (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
, the output terminal turns ON (OFF
for negative logic). By setting 0, the output terminal turns
OFF (ON for negative logic).

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 ON
reset (including a power failure) clears the REM signal
output. (The ON/OFF status of the terminals are as set in
Pr.
190 or Pr. 192 ) The Pr. 496 setting becomes also "0".
When Pr. 495 = "1, 11", the remote output data before power
OFF is stored into the EEPROM, so the signal output at
power recovery is the same as before power OFF. However,
it is not stored when the drive unit 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 a drive unit reset.
REMARKS
 The output terminal where the REM signal is not assigned using
Pr. 190
or
Pr. 192
does not turn ON/OFF if 0/1 is set to the
terminal bit of
Pr. 496
. (It turns ON/OFF with the assigned function.)
Parameters referred to
Pr. 190, Pr. 192 (output terminal function selection) Refer to page 123.
