Figure 43: Remote Reference
The remote reference is calculated once in every scan interval and initially consists of 2 types of reference inputs:
l X (the external reference): A sum (see P 5.5.3.5 T34 Low Current) of up to 4 externally selected references, comprising any
combination (determined by the setting of P 5.5.3.7 Reference 1 Source, P 5.5.3.8 Reference 2 Source, and P 5.5.3.9 Reference 3 Source)
of a fixed preset reference (P 5.5.3.10 Preset Reference), variable analog references, variable digital pulse references, and various
fieldbus references in any unit the drive is monitoring ([Hz], [RPM], [Nm], and so on).
l Y (the relative reference): A sum of 1 fixed preset reference (P 5.5.3.11 Preset Relative Reference) and 1 variable analog reference (P
5.5.3.12 Relative Scaling Reference Resource) in [%].
