Selection and protection of a motor
(2)
Use two 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.

REMARKS
The RT signal acts as the second function selection signal and makes the other second functions valid. (Refer to page 141)
