During the period of starting a motor or increasing the output frequency, the output current of the
inverter will increase. Once the output current exceeds the pre-set upper limit (as in the following
figure), adjustment of the output frequency will be paused automatically and will not proceed until
the motor has reached the output frequency (at this moment, the output current of the inverter will
decrease correspondingly).

5.12 Output Frequency Filtering Constant (P.28)
P.28 “Output frequency filtering constant”
Decreasing the acceleration/deceleration time or altering the output frequency from high-frequency
to low-frequency or vice versa can cause machine vibration and thereby affecting the product
quality.
To reduce the machine vibration, the output frequency can be filtered when altering from
high-frequency to low-frequency or vice versa by setting the output frequency filtering as a
constant P.28. The bigger the set value of P.28, the better the filtering effect, but the corresponding
response delay will increase. The filtering function is invalid if the set value of P.28 is 0.
