5.2.3 I< (lower limit)
Trip level, warning level
When monitoring current limits I< (lower limit), two different response
levels (trip level/warning level) can be parameterized and monitored. If the
current of the phases (I_max) drops below the response level, current limit
monitoring responds.
Trip level and warning level activity
The trip level/warning level is only effective when the motor is running, the
start-up procedure has been completed and there is no test position
feedback (TPF) (run+).
Response at trip level
Here you can set how SIMOCODE pro should respond when the trip level is
undershot:
See also "Tables of responses of SIMOCODE pro" in Chapter "Important
information".

Response at warning level
Here you can set how SIMOCODE pro should respond if the warning level is
undershot:

Hysteresis
Here you can set the hysteresis for the current limits I< (lower limit):
Trip level: 0 to 1020% of I
s
in 4% increments
Warning level: 0 to 1020% of I
s
in 4% increments
