Example 2: set the ACC time of 01H VFD as 10s and the DEC time as 20s.
P00.11 ACC time 1
ACC time means the time needed if the VFD
speeds up from 0Hz to the Max. One (P00.03).
DEC time means the time needed if the VFD
speeds down from the Max. Output frequency to
0Hz (P00.03).
Goodrive300 series VFDs define four groups of
ACC/DEC time which can be selected by P05.
The factory default ACC/DEC time of the VFD is
the first group.
