Jog Acceleration Time; Jog Deceleration Time - Delta Electronics AC Motor Drive VFD-E User Manual

The Acceleration Time is used to determine the time required for the AC motor drive to ramp
from 0 Hz to Maximum Output Frequency (Pr.01.00). The rate is linear unless S-Curve is
"Enabled"; see Pr.01.17.
The Deceleration Time is used to determine the time required for the AC motor drive to
decelerate from the Maximum Output Frequency (Pr.01.00) down to 0 Hz. The rate is linear
unless S-Curve is "Enabled.", see Pr.01.18.
The Acceleration/Deceleration Time 1, 2, 3, 4 are selected according to the Multi-function Input
Terminals Settings. See Pr.04.05 to Pr.04.08 for more details.
In the diagram shown below, the Acceleration/Deceleration Time of the AC motor drive is the
time between 0 Hz to Maximum Output Frequency (Pr.01.00). Suppose the Maximum Output
Frequency is 60 Hz, Minimum Output Frequency (Pr.01.05) is 1.0 Hz, and
Acceleration/Deceleration Time is 10 seconds. The actual time for the AC motor drive to
accelerate from start-up to 60 Hz and to decelerate from 60Hz to 1.0Hz is in this case 9.83
seconds. ((60-1) * 10/60=9.83secs).
