NOTES
When Pr. 49
≠
9999 (level changed according to frequency) and Pr. 48 = 0%
The stall prevention operation level is 0% at or higher than the frequency set in Pr. 49.
In the initial setting, the RT signal is assigned to the RT terminal. By setting "3" to any of
Pr. 178 to Pr. 189 "Input terminal function selection", you can assign the RT signal to the
other terminal.
Changing the terminal assignment using Pr. 178 to Pr. 189 "Input terminal function selec-
tion" may affect the other functions. Please make setting after confirming the function of
each terminal.
The RT (X9) signal acts as the second (third) function selection signal and makes the other
second functions valid.
