Section 5-3
Application
examples
These words con-
tain the automati-
cally calculated
frequency com-
mand value for the
inverter. (This value
is normally used.)
For example, if the
frequency setting
unit of the inverter
is 0.01 Hz, this
value can be used
as it in serial com-
munications with
the inverter. When
converting to an
analog output (0 to
5 V, 1 to 5 V, 0 to 10
V, 0 to 20 mA, or 4
to 20 mA), this
value can be used
to simplify the con-
version.
This value is used
when signed data
is not required, i.e.,
when using com-
munications or nor-
mal I/O to specify
the direction.
This value can be
used when not
using automatic
frequency com-
mand calculations
and instead to con-
vert the output
value provided
here in the user
program for output
to the inverter.
This value is used
when signed data
is required, i.e.,
when outputting
the frequency com-
mand with an ana-
log output from −10
to 10 V.
