AC DRIVE
•
Wizards for startup, PID control, multipump and fire mode to make the commissioning

•
The Funct button for an easy change between the local and the remote control place. The
remote control place can be I/O or fieldbus. You can make a selection of the remote
control place with a parameter.

•
A sleep mode function that automatically enables and disables the operation of the drive
to save energy.
•
A 2-zone PID controller with 2 different feedback signals: minimum and maximum
control.
•
2 setpoint sources for the PID control. You can make the selection with a digital input.
•
A function for PID setpoint boost.
•
A feedforward function to make the response to the process changes better.
•
A process value supervision.
•
A multipump control.
•
A pressure loss compensation to compensate pressure losses in the pipework for
example when the sensor is incorrectly placed near the pump or fan.
