• The following are the examples of the applications of the second (third) functions.
Switching between regular use and emergency use
Switching between heavy load and light load
Changing the acceleration/deceleration time
Switching characteristics of main motor and sub motor

• Turning ON the RT signal enables the second function, and turning ON the X9 signal enables the third function. The
following table shows the functions which can be changed to the second or third function.

*1 The function can be changed by switching the RT signal ON/OFF while the inverter is stopped. If a signal is switched during operation, the
operation method changes after the inverter stops. (Pr.450 ≠ 9999)
