Re: Running an Air Compressor with a VFD.
It may pay to stick an unloader valve in the air line that allows the motor to come up to full rpm until going on line.
The could be achieved with one of the outputs of the VFD set to Up-to-Speed.
An unloader is often used in the case of larger compressors.
Ensure you set the right pole count for the motor also, most are 4 pole motors.
