Figure 120: Configuration for using an instance in task time group 1 as DFT
reference
Assume instance SMAI_20_7:1 in task time group 1 has been selected in the
configuration to control the frequency tracking (For the SMAI_20_x of task time
group 1). Observe that the selected reference instance (i.e. frequency tracking master)
must be a voltage type. Observe that positive sequence voltage is used for the
frequency tracking feature.
For task time group 1 this gives the following settings (see Figure
119 for numbering):
SMAI_20_1:1 DFTRefExtOut = DFTRefGrp7 to route SMAI_20_7:1 reference to the
SPFCOUT output, DFTReference = DFTRefGrp7 for SMAI_20_7:1 to use
SMAI_20_7:1 as reference (see Figure
120). .
SMAI_20_2:1 - SMAI_20_12:1 DFTReference = DFTRefGrp7 for SMAI_20_2:1 -
SMAI_20_12:1 to use SMAI_20_7:1 as reference.
For task time group 2 this gives the following settings:
SMAI_20_2:2: DFTReference = ExternalDFTRef to use DFTSPFC input as
reference (SMAI_20_7:1); DFTRefExtOut = ExternalDFTRef (even if the output
SPCFOUT is not wired in AC).
SMAI_20_2:2 - SMAI_20_12:2 DFTReference = ExternalDFTRef to use DFTSPFC
input as reference (SMAI_20_7:1)
