PARAMETERS
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 page 442 for offlne auto tuning.)
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 second applied motor.
• If Pr.450  9999, the following parameters will be enabled by turning ON the Second function selection(RT) signal.
NOTE
• The RT signal is a second function selection signal. The RT signal also enables other second functions. (Refer to page 434.)
• The RT signal is assigned to the terminal RT in the initial status. Set "3" in any of Pr.178 to Pr.189 (input terminal function
selection) to assign the RT signal to another terminal.
• 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.
