F8-06 and F8-07 respectively record the obtained no-load and full-load data after the
load cell auto-tuning is successful. You can also monitor the current load condition in
the car by viewing F8-05. When the current load exceeds 110% of the rated load, the
system reports overload warning.
◆
Note that F8-05 to F8-07 record the binary data indicating the car load condi-
tion rather than the ratio of actual car data to the rated car load.
