Speed control under Real sensorless vector control, vector control, PM sensorless vector control
Pr. 1005 "Notch filter width"
● This sets the width of the frequency to which to apply the notch filter. The setting can be adjusted
according to the width of the frequency range to be excluded.
● If the width is too wide, the response level of speed control will drop, and the system may become
If a value higher than 500 Hz is set in Pr. 1003 while the response speed is normal (Pr. 800 = any of
"0 to 5 and 9 to 14"), the inverter operates at 500 Hz.
