Selection and protection of a motor
To use two types of 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, the second motor is valid with the RT signal ON.
For the RT signal, set "3" in any of Pr. 178 to Pr. 182 (input terminal function selection) to assign the function.
The setting is invalid under the IPM motor control.
The RT signal acts as the second function selection signal and makes the other second functions valid. (Refer to page 137)
Changing the terminal assignment using Pr. 178 to Pr. 182 (input terminal function selection) may affect other functions.
Set parameters after confirming the function of each terminal.
Make sure to set this parameter correctly according to the motor used.
Incorrect setting may cause the motor to overheat and burn.
