Intelligent pump control (IPC)
The Intelligent pump control (IPC) system can be used to control the speed/frequency
of multiple pumps in a pump system. Each pump is connected to a separate drive.
The IPC system supports redundancy, so that in case of a pump failure or a drive is
disconnected for maintenance, the system still continues the operation with the
remaining drives. The IPC system can be enabled with parameter
The IPC system at first increases the pump speed and if this speed is not sufficient,
the system will start a new pump based on process demand. While starting a new
pump, the speed of the already running pumps is reduced to allow smooth flow of
liquid.
In an IPC system, the drives communicates through inverter-to-inverter link on
embedded fieldbus. Each drive receives a start command through digital input DI and
a process value through analog input AI2.
Starting the IPC system
The IPC system starts operation when the drive receives a start command from
external control location EXT2 (parameter
). The start
command indicates that the pump is available to the IPC system. However, the
system sends the actual start command to the follower drives based on the required
output of the system.
If all drives in the system receive a start command simultaneously, then the drive with
the lowest node number will start as the master drive. See parameter
).
For optimal energy operation, you can combine the PID sleep function with IPC
system. For information on PID sleep function, see
(page
).
Note:
The IPC system is not active on external control location EXT1.
