The value is used to calculate the
current limit (PNU 281.1).
It must be sent by the PLC if it is
different from the DS7’s rated

281 1 rw CurrentLimit Unsigned16 Current limitation:
A current limitation can be
implemented here by using a PKE.
If the configured limit value is
reached, the DS7-SWD will freeze
the voltage ramp and set the CL bit
in the SWD input byte (profiles 7,
to 9, and 11). PNU 681.0 activates
and deactivates the current
limitation. If the PKE does not
deliver any current, but PNU 681.0
= 1 and the DS7-SWD is running,
the DIAG2 bit will be set and, in
profiles 4 to 11, the WARN bit will
be set as well.
Rated motor current I
m
(PNU
210.0) is used for calculating the
current limitation within this
context. The value is independent
from the PKE motor-protective
circuit-breaker and from the DS7-
SWD soft starter model.
