The standard parameterization has been used with a large number of proportional vales from various
manufacturers. This parameterization has proved to be good as long as no special demands concerning the
application have to be fulfilled.
7.8 Parameter description of the power stage
7.8.1 SIGNAL:M (Type of the monitor output signal)
Command Parameter Unit Group
SIGNAL:M x x= U0-10|I4-20 -
