Selection and protection of a motor
(2) Use two types motors (Pr. 450)
⋅ Set Pr. 450 Second applied motor to use two types motors with one inverter.
⋅ When "9999" (initial value) is set, no function is selected.
⋅ When Pr. 450
≠ 9999, turning the RT signal ON makes the following parameter valid.
REMARKS
⋅ When performing offline auto tuning, set "3, 7, 8, 13, 17, 18, 23, 33, 43, 53" in Pr. 71.
(Refer to page 189 for offline auto tuning)
⋅ For the 5.5K and 7.5K, the Pr. 0 Torque boost and Pr. 12 DC injection brake operation voltage settings are automatically changed
according to the Pr. 71 setting as follows.
REMARKS
⋅ The RT signal acts as the second function selection signal and makes the other second functions valid. (Refer to page 235)
⋅ 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.
CAUTION
⋅ 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.
CAUTION
Set this parameter correctly according to the motor used.
Incorrect setting may cause the motor to overheat and burn.
