ACS310 - Configuration of multipump and fan control with soft start

For more information, please visit: new.abb.com/dri...
This video shows how to configure parameters for multipump and fan control with a soft start for ABB general purpose drive, ACS310 after installation. In the multipump functionality, one pump is pressure controlled and auxiliary pumps are on/off controlled, based on capacity needs. It eliminates the need for an external programmable logic controller, reduces the motor stress and increases life time. The soft start lowers the pressure peaks on the pipelines and pumps. The new autochange functionality equalizes duty time between the pump motors, when auxiliary motors are not running.

Good day
I have a problem at (ACS580 DRIVE )
my function is multi pumps single drive (four pump booster )
i need to the booster work by (SPFC ) function
the FVD work by (SPFC) wile the number of motors running simultaneously are less from three pumps only
for example
the pump-1 run with VFD when it reach to full speed the the VFD trans to pump-2 and the pump-1 will run DOL then when the pump-2 reach to full speed must be the VFD trans to pump-3 and the pump-2 run DOL
but But what happens the VFD return to pump-1 and the pump-3 run DOL
note: the system work by (PFC ) function well
pleas i need to help
thank
