Description
the starting frequency, the VFD will be standby
rather than running. The starting frequency value
is unlimited by the lower limit frequency.
Setting range: 0.0–50.0s
During starting, the VFD will first perform DC
braking based on the set DC braking current
before startup, and then it will accelerate after the
set DC braking time before startup elapses. If the
set DC braking time is 0, DC braking will be invalid.
The larger the DC braking current, the stronger the
braking force. The DC braking current before
startup refers to the percentage relative to rated
VFD output current.
Setting range of P01.03: 0.0–100.0%
Setting range of P01.04: 0.00–50.00s
This function code is used to select the frequency
variation mode during starting and running.
0: Straight line; the output frequency increases or
decreases in straight line;
Output frequency f
fmax
t1
1: S curve; the output frequency increases or
decreases in S curve;
S curve is generally used in cases where smooth
start/stop is required, such as elevator, conveyer
belt, and so on.
Output frequency f
fmax
t1
Note: When set to 1, it is required to set P01.06,
P01.07, P01.27 and P01.28 accordingly.
