3-14 Preset Relative Reference
Range: Function:
0.00 %* [-100.00 - 100.00 %] The actual reference, X, is increased or decreased with the percentage Y, set in par.3-14

3-15 Reference 1 Source
Option: Function:
Select the reference input to be used for the first reference signal. par.3-15 Reference 1 Source ,
par.3-16 Reference 2 Source and par.3-17 Reference 3 Source define up to three different reference
signals. The sum of these reference signals defines the actual reference.
This parameter cannot be adjusted while the motor is running.
