Function assignment of external terminals
When Pr. 495 = "0" (initial value) or "10", 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,
Pr. 192 or Pr. 197.) The Pr. 496 setting is also "0".
When Pr. 495 = "1" or "11", the remote output data before power supply-off is stored into the
E²PROM, so the signal output at power recovery is the same as before power supply-off. How-
ever, it is not stored when the inverter is reset (terminal reset, reset request through commu-
nication). (See the chart below).
When Pr. 495 = "10" or "11", signal before rest is saved even at inverter reset.
Fig. 6-58: ON/OFF example for source logic
Fig. 6-59: Signal condition during a reset
When Pr. 495 = "1," the signal condition saved in EEPROM (condition of the last power OFF)
is applied.
NOTES The output terminal where the REM signal is not assigned using any of Pr. 190, Pr. 192 or
Pr. 197 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.)
