To find the Acceleration/Deceleration times for speed settings other than 100%, the following simple formula can be used to calculate the value:

Where:
T = New Ramp Up/Down time
Speed = New Speed in RPM from Speed switches 1 thru 5
Max RPM = 5800
TMax = Time value from Accel/Decel chart

Example

For example, let’s say we have selected the Speed DIP switches for the 4000 RPM setting:

Speed switches 1 thru 5 = ON/OFF/OFF/OFF/ON

And we have selected Accel/Decel switches for the 1.200 second setting:

Accel/Decel switches 7 thru 10 = ON/OFF/ON/OFF

The calculated time will be:
