Parameter Assignment For Em 4 F-Ai Ex Hart - Siemens SIMATIC PCS 7 Operating Manual

Overload
If you use the parameter "overload" in addition to the parameter "short-circuit level", the
following will result:
● In the range between employing the current limiting (the inflection point on the output
curve) up to the reaching of the short-circuit level, an "overload" diagnostic is transmitted
and an entry in the diagnostic buffer is made, without the module switching off the
channel.
● The "short-circuit level" parameter in turn determines the value of the load which, if
undershot, leads to the module diagnosing a short circuit and switching off the channel.
