overload.

Inactive, message, warn-

ing or malfunction can be

parameterized in U02

When triggering an event, a current limit initially

takes place in the servo and vector control control

types. At the same time, a fast stop is triggered as

a malfunction when parameterizing in U02. Re-

ducing the current can cause the fast stop to no

longer perform correctly.
