These parameters are made available for control by analog inputs which are required to be frequency references.
The programmed input is automatically scaled such that 100.0% input corresponds to the set maximum speed (1.06 or
21.01). Also the 0% input level corresponds to the minimum speed level (1.07 or 21.02) if Allow negative digital references
(1.10) is not selected.
Although the drive’s analog inputs (7.01, 7.02) cannot provide negative speed references, if the analog input destination
parameters (7.10, 7.14) are directed away from the analog reference parameters (1.36, 1.37), then negative values can be
written to them over the serial interface.
These bits are provided for control by logic input terminals for external reference selection (see parameters 1.14, 21.03 and
1.15).
Although parameters 1.41 to 1.47 are Read only parameters, they can be written to but only via a digital input.
