Reference potential for the digital inputs/outputs and analog input

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 recti󹪝ed.

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.
