The change in resistance is not proportional to the winding temperature
change.
The evaluation circuit signal in the SIMODRIVE converter must be externally
evaluated.
High, brief overload conditions, require additional protective measures, as a
result of the thermal coupling time of the sensor.
The temperature sensor cables are included in the pre–assembled encoder
cables.
Caution
!
The integrated temperature sensor protects the servomotors from overload
conditions up to 4<I
For servomotors (shaft heights 36 and 48), the temperature sensor only pro-
tects up to 2<I
For thermally critical load situations, i.e. high overload when the motor is at a
standstill, adequate protection is no longer provided. For example, a thermal
overcurrent relay must be provided as additional protection.
