Chilled Water Pump Control using VFD

Chilled Water Pump Control using VFD

Chilled Water Pump Control using VFD

(OP)
I am using a VFD to control a constant pressure water pump.In the technical specifications of the pump,it says 90% load at 50 hz.
1.Is it possible for me to load the pump above 90% by using VFD?(by increasing/decreasing frequency?)
2.If I were to operate the pump at 45 hz,what would the motor current be?Please provide me formula for relation between current and frequency...

Thanks & Regards,

Alan
