 Tuning the second motor (Pr.463)
• When one inverter switches the operation between two different motors, set the second motor in Pr.450 Second applied
motor, set Pr.463 Second motor auto tuning setting/status = "11", and perform tuning of the second motor.
• Turning ON the RT signal enables the parameter settings for the second motor as shown in the following table.

NOTE
• To use the RT signal, set "3" in any parameter from Pr.178 to Pr.189 (Input terminal function selection) to assign the
function to an input 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.
