5.2 Current limit monitoring
5.2.1 Description
Current limit monitoring is used for process monitoring, independent of
overload protection.
SIMOCODE pro supports two-phase monitoring of the motor current for
freely-selectable upper and lower current limits. The response of
SIMOCODE pro when a pre-warning or trip level has been reached can be
freely parameterized and delayed.
Motor current measurement is carried out via current measuring modules or
current/voltage measuring modules.
