Encoder connection
The S120 Combi supports sin/cos encoders, TTL encoders and encoders with integrated
DRIVE-CLiQ with a 5 V supply for motors. The TTL encoder is connected via the integrated
X220 encoder interface and is permanently assigned to spindle output X2. The sin/cos
encoder for spindle output X2 is connected to interface X205 via an SMx20 Sensor Module.
In this particular case, encoder interface X220 is automatically inactive.
Fixed topology rules apply when connecting DRIVE-CLiQ encoders. Each feed axis is
precisely assigned one DRIVE-CLiQ interface (see Chapter "Topology rules for DRIVE-
CLiQ").
HTL encoders, SSI encoders and a 24 V encoder power supply are not supported.
Interface assignment
The assignment of the interfaces on the S120 Combi is permanently defined and must not
be changed.
The DRIVE-CLiQ connection of the expansion axes is always implemented via DRIVE-CLiQ
interface X101 at the SINUMERIK control. A detailed description is provided in the chapters
"Interface description" of the S120 Combi and "Topology rules for DRIVE-CLiQ".
Measuring systems and additional encoders should always be connected via the DMC20
Hub Module.
Internal temperature sensing and internal fan
The internal temperature of the S120 Combi is sensed. In conjunction with this is the
temperature-dependent control of the internal fan to cool the inside of the unit. The
S120 Combi Power Module is switched off if its internal temperature becomes too high.
An operating hours counter for the internal fan is available via the software in parameter
P0254 (infeed).
