Important note:
Nominal field voltage and field current of the motor has to be within the field
controller operating range. For application with constant field it is easy to
check:
Transfer values of field current and field voltage to the diagram and check
that the point of intersection is within the operating range.

For field weakening application do that check with
nominal values and minimal values. Both points of
intersection have to be within the operating range.
Depend on the converter use the right diagram
(6 A or 20 A)
e.g. DCS401.0045
