4.4 Overcurrent operation
The controllers are designed for an overcurrent limited in time. The load due to defined,
cyclic operation is determined by the "Ixt" monitoring function. The "Ixt" function
comprises two moving averaging procedures which are checked in parallel:
ƒ temporary moving averaging of the apparent motor current for pulse loads
ƒ continuous moving averaging of the apparent motor current for permanent loads

If the maximum value in code C00064/1 exceeds 100%, a "warning" will be generated or
a "trip" will be triggered (according to setting).
