Default I/O configuration and connection example of the Pump and fan
Control Application with autochange

converter controls the speed of the variable
speed drive and gives control signals to Start
and Stop auxiliary drives to control the total
flow.

The application has two control sources on
I/O terminals. Source A is Pump and fan
control and source B is direct frequency
reference. The control source is selected with
DIB6 input.

1 General

Pump and fan control with autochange can be
selected by setting the value of parameter 0.1
to 0.

The application can be used to control one
variable speed drive and 0-4 auxiliary drives.
Additionally the motor connected to the
frequency converter and the start order of the
auxiliary drives can be changed with the
autochange function and external relay
system. The PI-controller of the frequency

Note! Remember to connect CMA and CMB inputs
