303 REFERENCE SCALING, MINIMUM VALUE 2346 (2.2.4, 2.2.16, 2.2.2.6)
304 REFERENCE SCALING, MAXIMUM VALUE 2346 (2.2.5, 2.2.17, 2.2.2.7)
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).
