P00.11
Acceleration
time 1
Acceleration time is the time needed for accelerating
from 0Hz to Max. output frequency (P00.03).
Deceleration time is the time needed from decelerating
from Max. output frequency (P00.03) to 0Hz.
TD350 series VFD defines four groups of acceleration
and deceleration time, which can be selected via
multi-function digital input terminals (P05 group). The
acceleration/deceleration time of the VFD is the first
group by default.
