2.6.5 Temperature monitoring
PT1000 sensors are installed as standard in the N(BS) winding head to protect the mo-
tor against thermal overload when the temperature change is slow (temperature change
in minutes or hours).
NOTICE
Operating voltage too high!
Destruction of the temperature sensor!
►
The maximum operating voltage of the temperature sensor must not
exceed DC 30 V.
Due to the non-ideal thermal coupling, the temperature sensor follows rapid winding
temperature changes only with delay, thus being unable to protect the winding if the
thermal overload of the motor is transient and high. Therefore, additional protection is
required (e.g. I
2
x t - monitoring by the drive controller) to protect the motor from fast-ris-
ing thermal overload.
NOTICE
Avoid rapid temperature changes!
Damage to the motor winding due to overload!
The evaluation of the temperature sensor belongs to the monitoring of
the motor winding. The temperature sensor follows rapit temperature
changes only with delay.
