Temperature monitoring and thermal motor protection
5.1.2.1
Temperature monitoring circuits Temp-S and Temp-F
The motors are equipped with the two temperature monitoring circuits - Temp‑S and Temp‑F -
that are described below.
• Temp‑S activates the thermal motor protection when the motor windings are thermally
overloaded. In this case the precondition is that Temp-S is correctly connected and evaluated.
For a thermal overload, the drive system must bring the motor into a no-current condition.
• Temp-F is used for temperature monitoring and diagnostics during commissioning and in
operation.
Both temperature monitoring circuits are independent of one another.
For example, the SME12x Sensor Module or the TM120 Terminal Module evaluates the
temperature sensor signals.
You can obtain commissioning information from Technical Support. Contact data is provided in
the introduction.
Temp‑S
All motors are equipped with the following temperature monitoring circuit to protect the motor
winding against thermal overload:
• 1 x PTC 130 °C temperature sensor per phase winding U, V and W, i.e. response threshold at
130 °C
In addition, 1FW6090-xxxxx-xxx2 to 1FW6290-xxxxx-xxx2 motors are equipped with the
following temperature monitoring circuit:
• 1 x PTC 150 °C temperature sensor for each phase winding U, V and W, response threshold
at 150 °C
The three PTC temperature sensors (PTC thermistor temperature sensors) of this temperature
monitoring circuit are connected in series with a PTC triplet.
