 Tuning the second motor
• When one inverter switches the operation between two different motors, set the second motor in Pr.450 Second applied
motor. (Refer to page 294.) In the initial setting, no second motor is applied.
• Turning ON the RT signal enables the parameter settings for the second motor as follows. For the RT signal, set "3" in any
parameter from Pr.178 to Pr.189 (Input terminal function selection) to assign the function.
Function
Motor capacity
Number of motor poles
Motor excitation current
Rated motor voltage
Rated motor frequency
Motor constant (R1)
Motor constant (R2)
Motor constant (L1)/d-axis inductance (Ld)
Motor constant (L2)/q-axis inductance (Lq)
Motor constant (X)

NOTE
• 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.
