4.30 Remote output (Pr. 495 to Pr.497)
4.30.1 Remote output function (Pr. 495 to Pr.497
You can utilize the on/off of the inverter's output signals instead of the remote output function of the
programmable controller.(Use Pr. 190 to Pr. 192 and Pr. 195 to set the output signals. Refer to page 165.)

(1) Operation
By setting 1 in the corresponding bit of Pr. 496, the output terminal that has been set to 96 (positive logic) or 196 (negative
logic) in any of Pr. 190 to Pr. 192 and Pr. 195 turns on (off for negative logic). By setting 0, the output terminal turns off (on
for negative logic).
If a power failure occurs at the Pr. 495 setting of 0, the output data are cleared to zero after power recovery and the output
terminals turn on/off in accordance with the positive/negative logic settings of Pr. 190 to Pr. 192 and Pr. 195.
When the Pr. 495 setting is 1, the remote output data at occurrence of a power failure are stored into E
output data at power recovery the same as those at a power failure, and the on/off states of the output terminals are also
made the same as those at a power failure. (They are not stored at an inverter reset.)
If the terminals of remote output and non-remote output are mixed using Pr. 190 to Pr. 192 and Pr. 195, the terminal to
which remote output is not assigned will not turn on/off even if 0/1 is set in the corresponding bit of the remote output data
(Pr. 496), and that terminal turns on/off with respect to the selected function.
(2) Others
Setting Pr. 496, Pr. 497 with the PU/DU, by computer link through the PU connector, or by communication through the
communication option allows the on/off control of the remote output terminals.
Pr. 496, Pr. 497 is always accessible by making access to RAM only. When the inverter is reset, therefore, the Pr. 496, Pr.
497 setting changes to 0. When Pr. 495 = 1, however, that setting is the same as at a power failure.
If you change the Pr. 495 setting of 1 to 0 with the Pr. 496 and Pr. 497 value stored in E
failure, the Pr. 496 and Pr. 497 value stored changes to 0.
CAUTION
When Pr. 495 = 1, take such a step as to connect R1, S1 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.
