Spindle functions
10.3 Spindle diagnostics
Alarms:
● 207017 = additional temperature alarm threshold violated
● 207018 = additional temperature fault threshold violated
10.3.5 Temperature histograms
The motor temperature and optionally additional temperatures, such as bearing temperature
or housing temperature, are displayed in a histogram. The color coding indicates the following
temperature ranges:
Color
The heights of the individual bar fields correspond to the parameterized temperature ranges
of the relevant temperature measuring point.
The specified times for the individual temperature ranges of a measuring point (sensor) are
the operating hours under speed.
The currently measured temperatures are displayed below the bars.
10.3.6 Speed/torque
To check the loads on the spindle, the speed and the torque are recorded in a histogram as
a function of the operating hours. The color coding indicates the following states:
● Light green: low load
● Green: rated load
● Yellow: high load
● Orange: critical load
The heights of the individual bars correspond to the percentage time shares (dwell time) in
relation to the operating hours under speed. The accumulated number of operating hours under
speed for the spindle are shown above or below the respective bar for the corresponding speed
or torque range. The width of the bar corresponds to the evaluated speed or torque range.
