6.9.3 Condition selection of function validity by second function selection
signal (RT, Pr. 155)
You can select the second function using the RT signal. For the RT signal, set "3" in any of
Pr. 178 to Pr. 182 to assign the function.
The second function has the following applications:
●
Switching between normal use and emergency use.
●
Switching between heavy load and light load.
●
Changing of acceleration/deceleration time by broken line acceleration/deceleration.
●
Switching of characteristic between main motor and sub motor.
Following functions that can be set as second functions:

NOTES When the RT signal is on, the above second function is selected at the same time.
Changing the terminal assignment using Pr. 178 to Pr. 182 may affect the other functions.
Make setting after confirming the function of each terminal.
