PARAMETER DESCRIPTIONS
303 REFERENCE SCALING, MINIMUM VALUE 2346 (2.2.4, 2.2.16, 2.2.2.6)
Use this parameter to set additional reference scaling.
304 REFERENCE SCALING, MAXIMUM VALUE 2346 (2.2.5, 2.2.17, 2.2.2.7)
Use this parameter to set additional reference scaling.
If both parameter ID303 and parameter ID304 = 0 scaling is set off. The minimum and
maximum frequencies are used for scaling.
NOTE!
This scaling does not affect the fieldbus reference (scaled between Minimum
frequency (parameter ID101) and Maximum frequency (parameter ID102).

305 REFERENCE INVERSION 2 (2.2.6)
Use this parameter to invert the reference direction.
Inverts reference signal:
Max. input signal = Min. freq. reference
Min. input signal = Max. freq. reference
