FR-A800 5 - 429
●
When the RT (X9) signal is ON, the following second (third) functions are selected at the same time.
The function can be changed by switching the RT signal ON/OFF while the inverter is stopped. If
a signal is switched during operation, the operation method changes after the inverter stops,
(Pr. 450
≠
9999).
When the RT signal is OFF, the first function is selected and when it is ON, the second function is
selected.

Tab. 5-169: Functions, that can be set as second or third functions
NOTES RT signal is assigned to the terminal RT in the initial status. Set "3" in any of Pr. 178 to Pr. 189 (input
terminal function selection) to assign the RT signal to another terminal.
When both the RT signal and X9 signal are ON, the X9 signal (third function) is prioritized.
Changing the terminal assignment using Pr. 178 to Pr. 189 (input terminal function selection) may
affect the other functions. Set parameters after confirming the function of each terminal.
