Notes on commissioning SSI encoders

Using error bits
The number and position of error bits can vary for SSI (Synchronous Serial Interface)
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 "Parameterization" and
"Limitations" in this chapter) as otherwise an error code may be interpreted as position
information if faults are present.
Hardware requirements
● SMC20 Sensor Module Cabinet Mounted
● SME25 Sensor Module External
● SMC30 Sensor Module Cabinet Mounted
● SME125 Sensor Module External
● Control Unit (CU320-2, CU310-2 or CUA32): Either the Sensor Module must be
connected using DRIVE-CLiQ or an SSI encoder evaluation integrated in the Control
Unit.
