NOTICE
Damage or malfunction due to impermissible voltage values
If a current exceeding ±35 mA flows through the analog current input, then the component
could be destroyed.
The common mode range must not be violated in order to avoid incorrect analog-digital
conversion results.
• The input voltage may only be in the range between -30 V and +30 V (destruction limit).
• The common mode voltage may only be in the range between -10 V and +10 V (error
• The back EMF at the auxiliary voltage outputs may only be in the range between -15 V
Note
The voltage supply for the analog inputs can be taken internally or from an external voltage
source.
