HEIDENHAIN MANUALPLUS 620 - 6.17.7 Temperature monitoring

962 HEIDENHAIN Technical Manual MANUALplus 620
6.17.7 Temperature monitoring
Temperature of the
MC
The internal temperature of the MC is continuously monitored. At about 55 °C
the early warning Temperature warning appears. If the temperature does not
fall below 55 °C, the warning is reactivated after two minutes. Beginning at
about 60 °C the error message Temperature too high <temperature> °C
appears and an emergency stop is triggered. If the temperature does not fall
below 60 °C when the machine is switched on again, the error message
reappears after 10 to 20 seconds.
Interrogate the
values of the
internal ADCs
Module 9133 allows you to interrogate the internal values of the analog-to-
digital converter of the MC.
