2.14 Notes on commissioning SSI encoders

Figure 2-42 Setting of the measuring socket T0 on CU320
When the drive is synchronized, the difference between the EMF/phase U and the electrical
rotor position is a maximum of 10°.
If the difference is greater, the commutation angle offset must be adjusted.
2.14 Notes on commissioning SSI encoders
Using error bits
The number and position of error bits may vary for SSI encoders. In the event of faults, error
codes may even sometimes be transferred within the position information.
It is therefore essential that you assess all the error bits present (see below for
parameterization and limitations) as otherwise an error code may be interpreted as position
information if faults are present.
