4.2.24 Two-stage acceleration/deceleration function (2CH)
The two-stage acceleration/deceleration function allows you to
change the acceleration or deceleration time while the inverter is
accelerating or decelerating the motor.
Select one of the following three methods of changing the
acceleration or deceleration time:
1) Changing the time by the signal input to an intelligent input
terminal
2) Automatically changing the time when the output frequency
reaches a specified frequency
3) Automatically changing the time only when switching the
motor operation from forward rotation to reverse rotation, or
vice versa
Selecting the 3rd control system enables the change of the
acceleration or deceleration time only by terminal input. Not bytwo-stage acceleration/deceleration
frequency.
To change the acceleration/deceleration time by the signal input to an intelligent input terminal, assign
function "09" (2CH) to one of the terminal functions C001 to C008.
