What is the Pump Curve Characteristic function on the Altivar 6xx Process Drive?

This behavior allow the drive to better know what is behind the motor, it it then possible to know how is the status of installation. It allows the user to know through drive information how is working the application. As example, the drives know the motor speed, it also knows the motor current, then it knows the motor torque ... With all those information, the drives knows the pump status, how it is position on its diagram and it is then possible to determinate the pump running point and then it is possible for the user's to change settings of installation in order to place installation on what we call "BEP", the best efficiency point. This is an example but many more function are related to the possibility of those curves included in the drive. This is linked to the global efficiency as well as availability of asset...

just to add to the Bruno's answer . Pump characteristic (example pressure vs flow)  means that you can enter 5 points of the pump curve ( pump manufacturer data)  . Then drive will show you the pump curve and the current working point in real time , including the BEP ( best efficiency point) . You can see this curve in the ATV600's display or via web server or SoMove . Additionally as we have the pump curve you can set different protections and functions . Thanks .
