Acceleration Deceleration Time 1 & 2 Parameter Setting in Delta VFD

Sometimes we want to start motor smoothly to high speed and sometime from speedily to low speed. We can have two times of acceleration and two times of deceleration. So in that case, we have to give acceleration and deceleration time in parameter 10, 11, 12 and 13.  Now there are two times setting we have of acceleration and deceleration. Parameter number 10 and 12 is acceleration and parameter number 11 and 13 are of deceleration time.

Now, the question is how we can change these time of acceleration and deceleration. We have to assign a task to control terminal, let's take "M3" terminal. This will switch out to second acceleration time when we will energize "M3" terminal. To assign M3, move to parameter number 42 and we should enter "11" to this parameter number 42. This parameter 42 tell us about first and second acceleration and deceleration time.

Acceleration Deceleration Speed Inhibit

In parameter 42, enter the value "10 and select acceleration deceleration speed inhibit function.  This will pause the acceleration.
