Lenze i510 - Load Loss Detection

10.5 Load loss detecon
This funcon serves to detect a load loss and to then acvate a specic funcon, for instance
the switching of the relay
.
Parameter Name / value range / [default seng] Info
0x4006:001
(PAR 710/001)
Load loss detecon: Threshold
(Load loss monit.:
Load loss threshold)
0.0 ... [0.0] ... 200.0 %
Threshold for load loss detecon.
•
The load loss detecon funcon is acvated if, with a rotang motor,
the present motor current falls below the threshold set here for at
least the me set in 0x4006:002 (PAR 710/002).
•
The load loss detecon status (internal "Load loss detecon" trigger)
can be assigned via the exible I/O conguraon, e.g. to a digital out-
put or a relay.
0x4006:002
(PAR 710/002)
Load loss detecon: Deceleraon
(Load loss monit.: Load loss delay)
0.0 ... [0.0] ... 300.0 s
Tripping delay for load loss detecon.
0x6075
(PAR 323)
Motor rated current
(Motor current)
0.001 ... [1.700]* ... 500.000 A
•
Default seng depending on the size.
•
Seng can only be changed if controller inhibit is
acve.
The rated motor current to be set here serves as a reference value for
dierent parameters with a seng/display in percent.
Relevant parameters:
•
DC braking: Current 0x2B84:001 (PAR 704/001)
