Lenze g500-H Series - Thermal Detectors PT1000

Thermal detectors PT1000
The thermal detector used connuously monitors the motor temperature. The temperature
informaon is transferred to the inverter using the system cable of the feedback system. This
is not a full motor protecon!
This makes it possible to determine the motor temperature in the permissible operang range
with great accuracy.
When supplying the thermal sensors with a measurement current of 1 mA, the
connecon between the temperature and the resistance measured applies.
