Temperature detection /KY (KTY84 – 130)
NOTICE
Excessive self-heating of the temperature sensor can damage the insulation of the
temperature detection as well as the motor winding.
The drive system might be damaged.
•
Use currents > 3 mA in the KTY circuit.
•
Observe the correct connection of the KTY to ensure correct evaluation of the
temperature detection.
•
Observe the polarity during connection.
The characteristic curve in the following figure shows the resistance curve subject to
the motor temperature with a measuring current of 2 mA and correct pole connection:
