FR-A700 EC 6 - 235
Tune second applied motor
●
When you want to switch two motors with one inverter, set the second motor in Pr. 450
"Second applied motor" (refer to section 6.12.2). Initial setting is without second applied
motor.
●
Turning the RT signal on makes the following parameters for the second parameters valid.

Tab. 6-61: Validation of parameters by the RT signal
NOTES The RT signal is assigned to the terminal RT in the initial setting. By setting "3" in 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
selection" may affect other functions. Make setting after confirming the function of each
terminal.
