Connecting a temperature sensor via the thermistor motor protection device

Use a MOTION-CONNECT cable to connect the signal cable from the terminal box.

Temp–S

If only one PTC is evaluated, then Temp–S 130 °C must be used. This should be connected to a thermistor motor protection tripping device. The thermistor motor protection tripping device – which is not included in the scope of supply – must be designed for safety isolation.

The thermistor motor protection device 3RN1013-1GW10 is available for this purpose (also refer to the diagram "Connection overview with motor protection devices").

Up to two PTC triplets (i.e. two stators) can be evaluated per sensor input at the thermistor motor protection tripping device.

Temp–F

For reasons relating to safety isolation according to EN 61800-5-1 (previously safe isolation according to EN 50178 (VDE 0160)), TEMP–F may not be directly evaluated in SIMODRIVE converters.

For commissioning purposes – evaluating the thermal utilization of the motor and optimizing the machine cycle – Temp-F can be evaluated using an external measuring device. (Ensure proper polarity!)

The measuring device must have a suitable electric strength in order to protect the operator from dangerous voltages (DC link voltage). The measuring system cables and their connectors must comply with the EN 61800-5-1 regulations.

After the measurements are completed and with the drive shut down, the Temp-F connection cables in the control cabinet must be connected to suitable free terminals so that they are safe to touch while ensuring the required clearances and creepage distances are met in compliance with EN 61800-5-1.
