Dependency: Refer to: r50012, r52051
Refer to: F60029, A60032
Note: Comments regarding PTC thermistors:
- PTC thermistors according to DIN 44081 / 44082 with the specified R for the rated response temperature.
- For Siemens motors, PTC thermistors with 1330 Ohm are used.
- Parameters p50491 and p50492 (alarm and switch-off temperature) are ineffective. The alarm and switch-off
temperatures are defined by the PTC thermistor type being used.
Comments on NTC thermistor K227:
The evaluation electronics on the CUD only allow resistance values of less than approx. 2 kOhm to be measured. As
a consequence, only temperatures greater than approx. 90 °C can be measured when using these temperature
sensors. For lower temperatures, the lowest possible value (approx. 90 °C) is displayed.
