NOTICE
Incorrect results of analog-to-digital conversion due to impermissible input voltage
The common mode range must not be violated.
Makes sure that the analog input voltage signals can have a maximum voltage of ±12 V with
respect to the reference potential. If the range is infringed, incorrect results may occur during
analog/digital conversion.
Note
A 24 V supply voltage must be connected to terminal X124 for the digital outputs to be used.
If momentary interruptions in the voltage occur in the 24 V supply, the digital outputs are
deactivated until the interruption has been rectified.
If a digital output (DO 8 ... DO 15) is parameterized and the external 24 V power supply is not
connected (or the level is too low), the alarm A03506 will be issued. This alarm can also be
parameterized as a fault.
For further details, see the SINAMICS S120/S150 List Manual, Section List of faults and alarms.
