positive or negative.
Actual Value
As described earlier in "Control Interface", Actual Values are words containing drive
values.
Actual Value Scaling
The scaling of the integers sent to the fieldbus as Actual Values depends on the
resolution of the selected drive parameter. Except as noted for Data Words 5 and 6
below, scale the feedback integer using the resolution listed for the parameter in the
"Parameter Descriptions" section. For example:
