Function:
[-100 - Enter up to 8 different preset references (0-7) in
this parameter, using array programming. Select
Preset Reference bit 0/1/2 [16] , [17] or [18] for
the corresponding digital inputs in parameter
group 5-1* Digital Inputs, for selecting dedicated
references. See also Table 3.4
Function:
[ 0 - 400.0 The jog speed is a fixed output speed at
which the frequency converter is running
when the jog function is activated.

Function:
Define fixed value in % to be added to variable
value defined in 3-18 Relative Scaling Reference
Resource, Relative Scaling Reference Source.
The sum of fixed and variable values (labelled Y in
Illustration 3.5) is multiplied with actual reference
(labelled X in Illustration 3.5). This product is added

Function:
Select the input to be used for the first
reference signal. 3-15 Reference 1 Source,
3-16 Reference 2 Source and
3-17 Reference 3 Source define up to
three different reference signals. The
sum of these reference signals defines
the actual reference.
