Upper limit
frequency source
Panel potentiometer setting
Setting upper limit frequency. The upper limit frequency can be set from either digital
setting (F0.21) or analog input channels. If the upper limit frequency is set from analog
input, the set 100% of analog input is relative to F0.21.
To avoid the "Runaway", the setting of upper limit frequency is required, when the inverter
reaches up to the set upper limit frequency value, the inverter will remain operation at the upper
limit frequency, no further increase.
F0.23(lower limit frequency)~F0.19(maximum
frequency)
0.00Hz~F0.21(upper limit frequency)
When the frequency command is lower than the lower limit frequency set by F0.23, the
inverter can shut down, and then run at the lower limit frequency or the zero speed; the running
mode can be set by F7.18.
By changing the parameters, the motor steering can be achieved without changing the motor
wiring, which acts as the adjustment of any two lines(U, V, W) of the motor to achieve the
conversion of the motor rotation direction.
Note: after the parameter is initialized, the motor running direction will be restored to its
original status. When the system debugging is completed, please use with caution where the
change of motor steering is strictly prohibited.
PV reduced
frequency curve
Down-conversion curve can make the inverter output frequency quickly decline, to avoid
power shortage lead to undervoltage. curve 4 is the fastest down, and curve 1 is the slowest. after
modify the parameters, power-on again then it effective.
