Adjustable time
The acceleration and deceleration time can be set.
Set a long time to accelerate or decelerate slowly or set a short
time to accelerate or decelerate quickly.
The time setting is the time it takes to accelerate from zero to the
maximum frequency and to decelerate from the maximum
frequency to zero.
When select the LAD cancel (LAC) function to intelligent input and turn on the signal
acceleration/deceleration time is disregarded and the output frequency flatters the command frequency
instantaneously.

However short you set the adjustable time, the adjustable time of the actual motor can’t be shorter than the
shortest
adjustable time determined by the inertial Effect J of the mechanical system and motor torque.
If you set the time shorter than the shortest adjustable time, a protection trip of OC or OV may occur.
