Pump inlet and outlet protection
The Pump inlet and outlet protection function monitors pump inlet and outlet
pressure and takes the user defined actions in case the pressure is outside the
normal range.
The inlet and outlet minimum pressure protection function can first generate a
warning when the pump pressure is below minimum pressure warning level for
pressure check delay time. If the pressure continues to fall below the minimum
pressure fault level, a fault is generated.
The outlet maximum pressure protection function can first generate a warning
when the pump outlet pressure is above maximum pressure warning level for
pressure check delay time. If the pressure continues to rise above the maximum
pressure fault level, a fault is generated.

Process PID control
The drive has a built-in process PID controller that controls process variables
such as pressure or pipe flow or fluid level in a container.
The process PID control has the following features:
• Uses the process reference/setpoint (water pressure or flow) as an
alternative to the speed reference.
• The actual value or the process feedback is the actual measured value fed
back to the drive.
• The PID control adjusts the drive speed to maintain the measured process
quantity (actual value) at the setpoint.
• Enables the drive to adjust its operation according to the process feedback.
Thus the user need not set the speed/frequency reference.
