Term Definition
Actual signal Type of parameter that is the result of a measurement or calculation by
the drive. Actual signals can be monitored, but not adjusted, by the user.
Parameter groups 1…9 typically contain actual signals.
Bit pointer setting A parameter setting that points to the value of a bit in another parameter
(usually an actual signal), or that can be fixed to 0 (FALSE) or 1 (TRUE).
When adjusting a bit pointer setting on the optional control panel, “Const”
is selected in order to fix the value to 0 (displayed as “C.False”) or 1
(“C.True”). “Pointer” is selected to define a source from another
parameter.
A pointer value is given in the format P.xx.yy.zz, where xx = parameter
group, yy = parameter index, zz = bit number.
Pointing to a nonexisting bit will be interpreted as 0 (FALSE).
In addition to the “Const” and “Pointer” selections, bit pointer settings may
also have other pre-selected settings.
FbEq Fieldbus equivalent. The scaling between the value shown on the panel
and the integer used in serial communication.
p.u. Per unit
Value pointer setting A parameter that points to the value of another actual signal or
parameter.
A pointer value is given in the format P.xx.yy, where xx = parameter
group, yy = parameter index.
