PRIMARY-7: Maximum Frequency
Max Frequency
7) 60Hz
Min: 30.00
Max: 240.00
Default: 60.00
ThePRIMARY‐7parametershouldbesettothe
maximum output frequency that VFD can
produceatfullspeedreferencesignal.Formost
standard industrial motors, it should be set to
50Hzor60Hz.
Max Frequency determines the full range of
the VFDspeed control (VFD outputfrequency).
The analog inpu
t range is scaled to VFD
maximumfrequency.
PRIMARY-8: Base Frequency
Base Frequency

VFD provides full output voltage at this
frequency.ThePRIMARY‐8parametershouldbe
