Reference Limits - Danfoss iC2 Application Manual

Application Guide | iC2-Micro Frequency Converters
The 2 types of reference inputs are combined in the following formula:
Remote reference=X+X*Y/100%
If relative reference is not used, set P 5.5.3.12 Relative Scaling Reference Resource to [0] No function and P 5.5.3.11 Preset Relative
Reference to 0%. The digital inputs on the drive can activate both the catch up/slow down function and the freeze reference function.

Reference Limits

5.6.2
The reference range, minimum reference, and maximum reference define the allowed range of the sum of all references. The sum of all
references is clamped when necessary. The relation between the resulting reference (after clamping) and the sum of all references are
shown in Figure 44 and Figure

The minimum reference cannot be set to less than 0, unless the configuration mode is set to Process. In that case, the following relations
between the resulting reference (after clamping) and the sum of all references are as shown in
