I am wanting to test the motor that will drive the blower of my cyclone; it is a 3kw 3 phase motor being run through a 3kw rated Huanyang vfd.

I am confused about the vfd manual's descriptions of certain parameters.

PD003 is for setting the "main frequency". I take this to mean the mains power supply frequency (i.e. 50Hz).

PD004 is for setting the "base frequency". I understand this to be the frequency the motor should be supplied with as stated on the compliance plate. My motor has figures for both 50Hz and 60Hz. As I would want maximum performance from the blower I would set this at 60Hz.

PD005 is for setting the "maximum operating frequency". I understand this to be the highest frequency output I desire from the vfd. Presumably this should be set at 60Hz since I do not want the blower motor running any faster than the maximum compliance plate figure.

Am I right about any of this? Advice from anyone with experience of an Huyanyang vfd would be greatly appreciated.

Cheers
