Constant power speed limit frequency = Power upper limit
* Motor rated frequency/Load detection value
The constant power mode is used for speed
adjustment. The constant power speed limit
frequency under the present load is calculated by
using algorithms (using P91.16, P91.17, and
P19.11 for reference).
(1) When P91.08=1, in constant power speed
boost mode, if the constant power speed limit
frequency is lower than or equal to the frequency
upper limit P00.04, the VFD runs at the constant
power speed limit frequency. At the same time, if
the set frequency is higher than or equal to the
constant power speed limit frequency, the speed
is limited at constant power; if the set frequency is
lower than the constant power speed limit
frequency, the speed boosts.
(2) When P91.08=2, in constant power speed limit
mode, if the constant power speed limit frequency
is lower than or equal to the frequency upper limit
P00.04: if the set frequency is higher than or equal
to the constant power speed limit frequency, the
speed is limited at constant power; if the set
frequency is lower than the constant power speed
limit frequency, the set frequency is used for
running.
