Note: 1.When P.300=3 for sensorless vector control is selected from P.300
control method, P.22 will be
used for the torque limited horizontal operation.
2. When P.220=2, if P.44 is not set, acceleration time is P.7; if P.45 is not set, deceleration time is P.8.
5.12 Output Frequency Filter Constant (P.28)
P.28 “Output frequency filter constant”
● When the acceleration or deceleration time decreases and the output frequency switches
from high-frequency to log-frequency, it may produce machine vibration which will affect
product quality.
● When output frequency filtering constant P.28 is set, the inverter can filter out the output
frequency to reduce machine vibration upon high-frequency and low-frequency is
switched. The bigger the P.28 is, the better the filtering effect is. But the corresponding
response delay will also increase. If P.28 is set to 0, the filtering function is invalid.
