The application is a conveyor in a sand plant. The conveyor has a 20hp motor on. I would like to be able to monitor how much power the motor
is pulling and the speed of the motor. I am aware that Allen Bradley and Cutler Hammer sell motor starters that will give this type of information over Device Net. The type of network connection is not all that important at this point.
Could a VFD be used for the same purpose? Plus gain the added benefit of a soft start? The speed would always be set at 60Hz. Besides maybe price what do you think the pros/cons would be between a VFD and an Intelligent motor starter for motor monitoring? Does anyone have any suggestions besides these two?
Ultimately the information will be used to control the load on the conveyor and if there are any abnormal conditions (Belt broke, overloaded, stalled, etc.).
Thanks for your help
