NOTE
• Regardless of the Pr.71 (Pr.450) setting, offline auto tuning can be performed according to Pr.96 (Pr.463) Auto tuning
setting/status. (Refer to
 Using two types of motors (RT signal, Pr.450)
• When using two types of motors with one inverter, set Pr.450 Second applied motor.
• The setting value "9999" (initial value) disables the second motor.
• If Pr.450 ≠ 9999, the following parameters will be enabled by turning ON the Second function selection (RT) signal.
