8.4.4 Additional temperature sensor
Shutdown response
The alarm and fault
thresholds of the additional temperature sensor that are displayed on the
user interface as limits, are stored in the SMI24. They are used only for the statistical evaluation
of the SMI24. A delay time setting for the violation of the alarm threshold stored in the SMI24
until the fault is triggered is not relevant for the display.
Please note: The parameter values of p4102[0..1] (alarm/fault threshold) and p4103 (delay
time) are predefined and cannot be changed.
Changing the parameter values of p4102[0..1] (alarm/fault threshold) and p4103 (delay time)
has no effect on the values displayed on the user interface.
The parameter values of p4102[0..1] (alarm/fault threshold) and p4103 (delay time) have an
effect on the shutdown response of the spindle. The spindle is shut down when the fault
threshold is violated or the alarm threshold is violated and the delay time set in p4103 has
expired. These parameters can be adapted accordingly to prevent an unwanted shutdown of
the spindle.
Currently, the delay time is not predefined by the SMI24. The parameter value of p4103 is set
to the factory setting (0 s). This means: The timer is deactivated.
Alarms:
● 207017 = additional temperature alarm threshold violated
● 207018 = additional temperature fault threshold violated
8.4.5 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 Meaning
Temperature range up to the first limit.
Temperature range between the first and second limit.
Temperature range above the second limit.
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.
