PowerFlex 40 Frequency

[travis 0]

Hello, I kinda confuse with the frequency parameter in PowerFlex 40. for P032 is it the line frequency or the motor output frequency? Addictional, How to determine the velocity motor drive by the PowerFlex40, I found out that my of output frequency didn't proportional with the velocity output. The induction motor is running a conveyor belt. If there is a slip, then the result I got shown the slip is very very high which more than 50%. Thanks a lot, great day. Edited 28 Feb 2013 by travis

P032 is the nameplate frequency of the motor, probably 50 or 60 Hz, see page 3-9, pdf page 55 of the User Manual. How did you determine your "50%" number? To accurately determine the belt speed, you may need some sort of encoder attached to the belt roller (or on the belt itself)
