Temperature sensor /PT (PT100)
NOTICE
Excessive self-heating of the temperature detection can damage the insulation of
the temperature detection as well as the motor winding.
The drive system might be damaged.
•
Avoid currents > 3 mA in the circuit of the PT100.
•
Observe the correct connection of the PT100 to ensure correct evaluation of the
temperature detection.
The characteristic curve in the following figure shows the resistance curve subject to
the motor temperature.
