P08.08
DEC time for jogging
output frequency (
P00.03).
DEC time for jogging means the time needed for
the VFD to decelerate from the max. output
frequency (
P00.03) to 0Hz.
Setting range: 0.0±3600.0s

ƻ
P08.09
Jump frequency 1
When the set frequency i
s within the range of
jump frequency, the VFD runs at the boundary of
jump frequency.
The VFD can avoid mechanical resonance points
by setting jump frequencies. The VFD supports
the setting of three jump frequencies. If the jump
frequency points are set to
0, this function is
invalid.
