Thermal detectors PT1000
The thermal detector used connuously monitors the motor temperature. The temperature
informaon is transferred to the inverter using the system cable of the feedback system. This
is not a full motor protecon!
This makes it possible to determine the motor temperature in the permissible operang range
with great accuracy.
When supplying the thermal sensors with a measurement current of 1 mA, the
connecon between the temperature and the resistance measured applies.
