common
(common
Second (third) function can be selected with the RT (X9)
signal.
When the RT signal turns ON, the second function
becomes valid.
When the X9 signal turns ON, the third function becomes
valid.
For RT signal, set "3" to any of [ Pr.178 to 189 Input terminal
function selection ] to assign the function. For X9 signal, set
"9" to any of [ Pr.178 to 189 Input terminal function selection ]
to assign the function.

The second (third) function has the following applications.
1) Switching between normal use and emergency
use
2) Switching between heavy load and light load
3) Changing of acceleration/deceleration time by
broken line acceleration/deceleration
4) Switching of characteristic between the main
motor and sub motor

Description
Second (third) function is immediately made
valid with ON of the RT (X9) signal.
Second (third) function is valid only during the
RT (X9) signal is ON and constant speed
