Setting multiple torque boosts (RT signal, X9 signal, Pr. 46, Pr. 112)
●
When changing the torque boost depending on the usage or when using single inverter switching
between multiple motors, use the second (third) torque boost.
●
Pr. 46 "Second torque boost" will become enabled when the RT signal turns ON.
●
Pr. 112 "Third torque boost" will become enabled when X9 signal turns ON. Set "9" in Pr. 178 to
Pr. 189 (input terminal function selection) to assign X9 signal function to a terminal.
NOTES
The RT (X9) signal acts as the second (third) function selection signal and makes the other second
(third) functions valid. (Refer to page 5-445.)
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.
Set a larger value when the distance between the inverter and the motor is long or when there is
not enough motor torque in the low-speed range. It may cause overcurrent trip when it is set too
large.
Setting for Pr. 0, Pr. 46, and Pr. 112 becomes enabled only when the V/F control is selected.
When the initial value is set in Pr. 0, the Pr. 0 setting is automatically changed by changing the Pr.
71 "Applied motor" and Pr. 81 "Number of motor poles" setting. (Refer to page 5-451.)
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.
