X9) (Rt Signal, X9 Signal, Pr. 155) - Mitsubishi Electric FR-A700 Instruction Manual

Function assignment of external terminals
6.14.3 Condition selection of function validity by the second function selection
signal (RT) and third function selection signal (X9) (RT signal, X9 signal,
Pr. 155)
You can select the second (third) function using the RT(X9) signal.
You can also set the condition (reflection conditon) where the second function and third function
become valid.

condition selection
When the RT signal turns on, the second function becomes valid.
When the X9 signal turns on, the third function becomes valid.
For the X9 signal, set "9" in any of Pr. 178 to Pr. 189 (input terminal function selection) to assign
the function.
The second (third) 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.
