Inserting An Encoder - Siemens SINAMICS S120 Commissioning Manual

Commissioning
4.4 Creating a project offline in Startdrive
● SSI encoder
Absolute encoders, which are controlled via the SSI protocol.
● Distance-coded zero marks
Zero marks are used when homing is not possible or accepted.
Note
Encoders from the hardware catalog
SIEMENS in-house encoders which are listed in the hardware catalog no longer have to be
parameterized as they are already preassigned the appropriate settings.
In contrast, third-party encoders must be parameterized as described below.
You can find exhaustive information about the encoders in Chapter "Important measuring
systems/encoders" of the SINAMICS S120 Commissioning Manual with STARTER.
4.4.8.2

Inserting an encoder

Preconditions
● A project has been created.
● The Control Unit is inserted in the device configuration.
● An infeed is inserted.
In case of doubt, you can also add the infeed at a later point in time. However, in this
case, you must manually wire the "infeed" component with the other components.
● A Motor Module is inserted.
● A motor is inserted (optional).
Utilizing this procedure, you insert the encoder after the motor (see Chapter "Sequence
when creating drive components (Page 83)").
