Parameter
Use two types motors (Pr. 450)
● Set Pr. 450 "Second applied motor" to use two different motors with one inverter.
● When "9999" (initial value) is set, no function is selected.
● When a value other than "9999" is set in Pr. 450 turning the RT signal on makes the following
parameter valid..
Function
Applied motor
Control method selection
Motor capacity
Number of motor poles
Motor excitation current
Motor rated voltage
Rated motor frequency
Motor constant (R1)
Motor constant (R2)
Motor constant (L1)
Motor constant (L2)
Motor constant (X)

Tab. 6-48: Validation of parameters by the RT signal
NOTES
The RT signal acts as the second function selection signal and makes the other second
functions valid. (Refer to section 6.14.3.)
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.
b
CAUTION:
Set this parameter correctly according to the motor used.
Incorrect setting may cause the motor to overheat and burn.
