NOTES The 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.
Changing the terminal assignment using Pr. 178 to Pr. 189 may affect other functions. Set parame-
ters after confirming the function of each terminal.
Pr. 14 will become enabled at the time of V/F control.
Other second functions will become enabled when the RT signal is ON.
