Selection and protection of a motor(6) Tune second applied motor· When you want to switch two motors with one inverter, set the second motor in Pr. 450 Second applied motor (refer topage 169). Initial setting is without second applied motor.· Turning the RT signal on makes the following parameters for the second parameters valid.FunctionsRT Signal ON(second motor)RT Signal OFF(first motor)Motor capacity Pr. 453 Pr. 80Number of motor poles Pr. 454 Pr. 81Motor excitation current Pr. 455 Pr. 82Rated motor voltage Pr. 456 Pr. 83Rated motor frequency Pr. 457 Pr. 84Motor constant (R1) Pr. 458 Pr. 90Motor constant (R2) Pr. 459 Pr. 91Motor constant (L1) Pr. 460 Pr. 92Motor constant (L2) Pr. 461 Pr. 93Motor constant (X) Pr. 462 Pr. 94Auto tuning setting/status Pr. 463 Pr. 96REMARKS· 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 functionselection), 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. Pleasemake setting after confirming the function of each terminal.♦ Parameters referred to ♦Pr. 7 Acceleration time, Pr. 8 Deceleration time Refer to page 155Pr. 9 Electronic thermal O/L relay Refer to page 165Pr. 71 Applied motor Refer to page 169Pr. 80 Motor capacity, Pr. 81 Number of motor poles Refer to page 75Pr. 95 Online auto tuning selection Refer to page 181Pr. 156 Stall prevention operation selection Refer to page 135Pr. 178 to Pr. 189 (input terminal function selection) Refer to page 206Pr. 190 to Pr. 196 (output terminal function selection) Refer to page 214Pr. 800 Control method selection Refer to page 75180
