S1: Spindles
16.9 Spindle with SMI 24 (Weiss spindle)
Note
Spindle with sensor module SMI 24 and axis container
A spindle with sensor module SMI 24 and drive telegram 139 for the transmission of sensor
data to the control must not be part of an axis container whose axes are distributed over
several NCUs via an NCU link.
Transmission of sensor data
Sensor data are transferred to the control from sensor module SMI 24 in cyclic drive telegram 139 as process
data 11 - 14. Drive telegram 139 is based on drive telegram 136, where sensor data are transferred instead of
the data of the 2nd encoder. A detailed description of drive telegram 139 can be found in:

System data: Sensor data
Sensor data can be read into the control via the following system data:
Meaning
Sensor configuration
1)
Clamped state
Measured value
2)
analog sensor S1
Status digital sensors
<axis>:
see Chapter "Clamped state [Page 1355]"
1)
Sensor S1: 0 - 10 V
2)
Analog actual value: 0 - 10000 increments, resolution 1 mV
Example:
SIMATIC S7 input module: 0 - 27648 increments, resolution 0.36 mV
Adaptation factor if you change to a spindle with SMI 24: 2,7648
