Tuning the second applied motor
• When one inverter switches the operation between two different motors, set the second motor in Pr.450 Second applied
motor. (Refer to page 423.) In the initial setting, no second motor is applied.
• Turning ON the RT signal will enable the parameter settings for the second motor as shown below.

NOTE
• 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 (Input terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.
