Motor current graph
The motor current data is recorded for up to 12 seconds and a curve of current over time is
graphed, displayed on the HMI and stored for future comparison:
HMI: Measurement / Operations charts / Spring
Via the HMI, the user is also able to display the previous curves saved in the CBW3:
Historical graphs
In addition, the following historical graphs are also available for:
Mean motor current value measured
-
Maximum (inrush) motor current value measured
-
Spring rewinding time measured
-
Outside ambient temperature when these measurements were made
-
These graphs enable users to quickly compare the latest value obtained to historical values
previously recorded and graphically visualise any change/deviation.
