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 (Pr 1.06 or Pr 21.01). Also the 0%
input level corresponds to the minimum speed level (Pr 1.07 or Pr 21.02) if negative references (Pr 1.10) is not selected.
See Pr 1.09.
These bits are provided for control by logic input terminals for external reference selection (see Pr 1.14 on page 40, and Pr 1.15 on page 41).
Pr 1.41 Analog reference 2 select (lowest priority)
Pr 1.42 Preset reference select
Pr 1.43 Keypad reference select
Pr 1.44 Precision reference select (highest priority)
If more than one of these parameters is active, the highest priority take precedence.
Indicates the reference currently being selected.
1: Analog reference 1 selected
2: Analog reference 2 selected
3: Preset reference selected
4: Keypad reference selected
5: Precision reference selected
